Antilles Gold Limited (“Antilles Gold” or the “Company”) (ASX: AAU, OTCQB: ANTMF) is pleased to advise positive results from the 21 diamond drill holes into the El Pilar oxide deposit in central Cuba, which completed the 10,600m 2023 campaign.
HIGHLIGHTS
Copper Domain – El Pilar
Gold Domain – El Pilar
Sampling Techniques and Data are set out in the JORC Code 2012 Edition Template attached.
EL PILAR OXIDE DEPOSIT
- The results continue excellent grades for both gold and copper in the oxide deposit that have previously been advised to ASX (4, 17, 27 July 2023, 8 August 2023, 21 September 2023, 23 October 2023, and 2 November 2023).
- These results plus those from 1,800m undertaken in 2022 and selected results from 24,000m of historic drilling reinforce the prospect of near term development of the low CAPEX Nueva Sabana mine at El Pilar.
- The outstanding grades in the gold domain extend from surface to a depth of 40m to 50m, and robust grades in the underlying copper domain continue for a further 50m to 70m.
- The gold zone within the oxide deposit is well defined, and the copper domain has increased in volume both laterally and vertically with continuing exploration, and projects into the underlying sulphide zone.
- A Mineral Resource Estimate (“MRE”) for the proposed Nueva Sabana mine is expected to be established within 3 or 4 weeks, and will be followed by a Scoping Study for the project around April 2024.
- The El Pilar oxide deposit is metallurgically simple, and the Nueva Sabana mine is being planned as a copper project which would benefit from the high grade gold cap during initial operations.
- Preliminary metallurgical test work by Blue Coast Research Laboratories in Canada has indicated a gold recovery of 85% from a simple rougher flotation circuit with a concentrate of 53.1 g/t Au produced from an ore sample grading 2.11 g/t Au.
- Test work is continuing on copper recoveries and concentrate grades, and early indications are that the copper concentrate will contain around 25% Cu.
- Planning and permitting for the proposed mine is well advanced.
- The recently revised construction cost estimate of ~US$22 million for the proposed mine, was based on a mining rate of 650,000tpa of ore.
- Negotiations have commenced to arrange an advance on purchases of the gold concentrate for a similar amount by an international commodities trader, in order to fund the construction.
- The low capital cost reflects the availability of HT power, rail and highway links to a container port, water supply, and skilled labour being close to the unoccupied flat mine site, together with low pre-stripping costs, and the ability to dry-hire all necessary mining equipment rather than purchasing a new fleet.
- Antilles Gold’s 50:50 joint venture with the Cuban Government’s mining company, GeoMinera, intends to develop the Nueva Sabana mine as soon as possible, and commencement of the 10 month mine construction is planned for July 2024.

Investor Insight
Antilles Gold’s gold and copper projects in Cuba are underpinned by a strong partnership with a Cuban Government-owned mining company that effectively fast-tracks and de-risks its promising projects, offering a strategic value proposition for investors.
Overview
Antilles Gold (ASX:AAU,OTCQB:ANTMF) is an Australian mining company focused on gold and copper projects in Cuba through a joint venture with the Cuban Government’s mining company, GeoMinera. This partnership has resulted in rapid project permitting and access to several new development opportunities for the Australian company.
Antilles Gold offers strong growth potential through two near‐term development projects, Nueva Sabana and La Demajagua, and two exploration projects, the El Pilar porphyry system and Sierra Maestra copper concessions.
Joint venture projects in Cuba
Nueva Sabana is a near‐term, gold‐copper mine development within the joint venture with GeoMinera, and is expected to initially produce around 70 grams per tonne (g/t) gold in a concentrate from a high‐grade gold cap followed by ~27 percent copper concentrate with gold credits. The project development strategy includes the completion of a feasibility study in September 2024, and the commencement of construction soon after.
The second proposed development is the La Demajagua open-pit mine, which is likely to produce ~50,000 tonnes per annum (tpa) of gold arsenopyrite concentrate (32 g/t gold, 27 percent arsenic), and ~10,000 tpa of gold antimony concentrate (28.8 g/t gold, 48 percent antimony, 1,200 g/t silver) for nine years. According to the plans, construction will commence in late 2025, with commissioning in mid‐2027. La Demajagua will also include the construction of a concentrate processing facility to treat La Demajagua’s gold arsenopyrite concentrate, with the capacity to produce 50,000 oz gold per year in dore, which will further increase JV profit and cashflow.
The joint venture’s two exploration projects comprise the 720‐hectare El Pilar Concession in Central Cuba covering a cluster of three copper‐gold porphyry deposits (El Pilar, Gaspar and San Nicholas), the adjacent 17,000 hectare San Nicholas concession with porphyry style mineralisation, and two concessions totaling 52,600 hectares within the producing Sierra Maestra copper belt in southeast Cuba (La Cristina and Vega Grande), with both indicating of porphyry deposits highly prospective for copper, gold and molybdenum.
Surface mineralisation at El Pilar
Antilles Gold has completed a technical evaluation of the El Pilar porphyry system which was advised to ASX on 15 February 2024.
The joint venture intends to invest part of the surplus cash flow from the Nueva Sabana mine to fund the exploration of major copper targets, including the El Pilar copper‐gold porphyry system, and those in the Sierra Maestra copper belt.

Key Projects
Nueva Sabana Project
Prominer Mining Technology will supply Nueva Sabana concentrator
Nueva Sabana is the company’s near‐term, gold‐copper mine development project. The project is held in the 50:50 joint venture with GeoMinera. It will be an open-pit mine developed on the oxide zone overlaying the El Pilar porphyry copper deposit in central Cuba.
Results from 24,000 metres of historical drilling, 1,800 metres drilled in 2022, and the 10,000 metres drilled in 2023 have established a mineral resource estimate (MRE). Results of a scoping study were advised to ASX on 7 May 2024, and a feasibility study is in progress for the proposed development which will be followed by a 12‐month construction phase.
Drilling has shown outstanding grades for gold and copper, and increasing lateral and vertical boundaries of the copper domain.
The proposed mining rate for the project will be 500,000 tpa of ore with a low waste‐to‐ore ratio. The anticipated initial production of 70 g/t gold concentrate will be followed by a ~27 percent copper concentrate with gold credits.
The estimated project cost is approximately US$33 million, of which approximately US$6 million is shareholders equity with the balance of $27 million expected to be funded through an advance on purchases of the concentrates by an international commodities trader.
Chinese engineering group, Prominer Mining Technology, which has extensive experience in designing and constructing gold and copper concentrators, is expected to supply the crushing and flotation circuits for the Nueva Sabana mine.
La Demajagua Project
La Demajagua involves the development of a gold‐antimony‐silver deposit as an open-pit mine by the joint venture company, Minera La Victoria.The project is located within a 900 hectare mining concession on the Isle of Youth, 60 nautical miles from mainland Cuba. The project site is 35 kilometres from the port city of Nueva Gerona and enjoys excellent infrastructure in terms of accessibility by highway, and availability of water, electricity and fiber optic cable.The project has an MRE of 905,000 oz gold equivalent for the open-pit operation. The MRE was calculated from 29,000 metres of drilling undertaken by the JV, and selective results from about 50,000 metres of historic drilling and revised after the receipt of additional antimony assays. The project expects mining of about 815,000 tpa of ore to produce two concentrates: 50,000 tpa of gold‐arsenopyrite and 10,000 tpa of gold‐antimony‐silver for nine years.
The project will also include a concentrate processing facility to produce gold doré from the gold-arsenopyrite concentrate. The facility will comprise a 50,000‐tpa two‐stage fluidized‐bed roaster, a carbon-in-leach (CIL) circuit, and an antimony recovery circuit. The overall production target is 75,000 oz gold equivalent per year. Chinese engineering firm BGRIMM Technology Group, which has extensive experience in designing and constructing roasters, is expected to supply the process plant on a turnkey basis.
The total development cost is estimated at US$165 million, expected to be funded by US$75 million of equity, which includes contributions by a third shareholder in the project, and the balance of US$90 million in debt. The life‐of‐mine cash surplus is estimated at ~US$600 million, with an NPV of ~US$330 million based on US$1,800/oz gold, and US$13,000/t antimony.
A revised scoping study including the concentrate processing facility is expected in December 2024, and construction is anticipated to commence in late 2025, with commissioning targeted for mid‐2027.
El Pilar Copper‐Gold Porphyry System Project
El Pilar is an exploration project of a cluster of three copper‐gold porphyry deposits: El Pilar, Gaspar and Camilo. The project comprises a 752 hectare exploration license and an adjacent 17,000 hectare reconnaissance permit covering the San Nicholas copper targets.
The project site benefits from established infrastructure with close access to a major highway, high‐tension power, and a 60 kilometre rail link to Palo Alto port.
Previous mapping, soil sampling, ground magnetics, an aeromagnetic survey and 24,000 metres of shallow drilling confirmed the existence of copper‐gold mineralization and identified the exposures as a potentially large, leached porphyry system. The surface exposures at El Pilar are leached phyllic caps to a cluster of copper‐gold porphyry cores. The extent of surficial hydrothermal alteration indicates the porphyry intrusions have large dimensions, and potential depths greater than 1,000 metres.
Ground magnetics and induced polarization surveys in early 2023 have confirmed a cluster of three potentially large porphyry intrusives – El Pilar, Gaspar and Camilo. A 10‐hole initial program has demonstrated positive results with good copper intercepts in porphyry‐style veining and has indicated the proximity of drilling to the core of El Pilar porphyry intrusive. In particular, drill hole PDH‐004A assayed 1.23 percent copper over its length of 134 metres from 49 metres.
Sierra Maestra Copper Belt Project
The project is an exploration project covering two highly prospective concessions for copper, gold and molybdenum in the Sierra Maestra copper belt in southeast Cuba. It includes a 3,600-hectare geological investigation license in La Cristina, and the adjoining 49,000‐hectare Vega Grande reconnaissance license.
The copper belt spans more than 200 kilometres of Cretaceous‐age geology intruded by Eocene stocks, which are the source of widespread gold and base‐metals mineralization. The project is near the El Cobre mine which is the oldest operating copper mine in the Americas. The concessions incorporate a series of copper‐gold‐molybdenum zones that display significant footprints of hydrothermal alteration normally associated with potentially large porphyry systems.
An extensive, two‐year prospecting program will be carried out on the two concessions, commencing in Q4 2024, to identify drill targets.

TEM | Yalgoo Update - Further Excellent Iron Results
Key Points
- Additional high-grade magnetite iron intercepted in RC drilling
- Consistent intercepts over >2 km of drilled strike length
- Identical outcropping geology mapped over a 5 km total strike length
- Potential for a large-scale iron ore deposit nearby other world-class processing facilities
Remorse Target
High-grade iron
In addition to the lab results for the first drillhole previously reported 1, the Company is pleased to announce the completion of drilling and that follow-up results in subsequent drillholes confirm the presence of high-grade iron at the Remorse Target. New results include:
WARDH00180 16m @ 32.6% Fe from 93m (pXRF)
WARDH00169 20m @ 32.3% Fe from 120m (pXRF)
and 11m @ 30.8% Fe from 182m (pXRF)
WARDH00166 7m @ 32.8% Fe from 96m (Lab)
WARDH00171 8m @ 30.1% Fe from 130m (pXRF)
* Portable XRF (pxrf) results are not comparable in reliability to authorised laboratory results and should be not relied on for quantitative purposes outside indicative demonstrations of potential order of magnitude of enrichments.
Background
TEM has completed the first phase of RC drilling at the Remorse Target of its flagship Yalgoo Project. In total, 21 RC holes were drilled for 4,005m. Samples have been Boxscanned (pXRF) and submitted to the lab and final assay results are expected in December 2024.
The previously reported iron intercept from the first hole drilled at Remorse was WARDH00160 of 32m @ 30.0% Fe from 96m (including 7m @ 37% Fe) (Lab).
The Remorse Target is part of Tempest's broader Yalgoo Project which spans over 1,000 square kilometres of prospective terrain for base metals, precious metals and iron ore.
Figure 01: Section through iron mineralisation WARDH00180
Figure 02: Section through iron mineralisation WARDH00169 and WARDH00163-165.
All samples collected have been analysed using a Boxscan unit which includes a mounted portable X-ray fluorescence (pXRF). Although not as accurate as laboratory analysis, pXRF data when collected in a quality and consistent manner can also exhibit high accuracy and precision. The pXRF data has been compared with assays received to date (>800 samples) and has an average variance of -4.2% and a median of -4.3%. The results indicate the accuracy is considered acceptable for current exploration reporting purposes (and potentially an overall slight underestimation by pXRF).
Remaining assay results are due in December and are expected to correlate strongly with the pxrf results announced.
As previously advised, the drill program design was focused on the strong base metal geochemical anomaly exhibited at the Remorse Target 2. The planned holes were focused strongly on testing the 'hanging wall' stratigraphy at Remorse and were not initially focused on the newly identified iron layer. However, the program did result in the 4 most northerly drill holes intercepting the main magnetite layer and numerous holes intercepting adjacent magnetite-rich layers.
The widely spaced drilling shows continuity and consistency over more than 2 kilometres and identical iron-rich stratigraphy outcrops can be traced over an extensive 5-kilometre zone correlating with the original Remorse Target footprint.

Brunswick Exploration
Investor Insight
With multiple significant lithium discoveries under its belt and a proven exploration strategy that yields results, Brunswick Exploration makes a compelling investment proposition in the ever- expanding lithium space.
Overview
Brunswick Exploration (TSXV:BRW,OTCQB:BRWXF,1XQ:FF) is among the only public companies aggressively and systematically conducting grassroots exploration for lithium in Canada and Greenland using state-of-the-art exploration technology to identify high-potential targets. Specifically, the company has staked major under-explored pegmatite fields across Quebec, Newfoundland and Labrador, Nova Scotia, New Brunswick, Ontario, Manitoba, Saskatchewan and Greenland.
Brunswick Exploration’s team of geologists begins by compiling available data and conducting research to identify locations where they believe the potential for minerals of interest might be
found. The technical field team is dispatched to conduct a prospecting program by gathering robust observational data using tried-and-true field geology techniques. The goal of the program is to reveal the presence of mineralization that may predict the presence of an unknown mineral deposit.
The company's exploration team is guided by its executive chairman Robert Wares, who co- founded the original Osisko Mining and was responsible for discovering the Canadian Malartic bulk tonnage gold mine. That mine was subsequently developed by Osisko into one of Canada's largest gold producers. Wares is an established and award-winning professional geologist with over 40 years of experience in mineral exploration and development.
Brunswick Exploration has identified five high-priority projects in the Eeyou Istchee-James Bay region of Quebec: Mirage, Elrond, Anatacau, PLEX and Mythril. In 2023, grassroots lithium discoveries were made at Mirage, Elrond and Anatacau, which are currently the focus of drilling.
In 2024, Brunswick Exploration successfully discovered Greenland’s first lithium-bearing spodumene pegmatitewithin the Ivisaartoq pegmatite field covered by the company’s Nuuk license. The Ivisaartoq pegmatite field is Mesoarchean in age and contains amphibolites, metasediments, ultramafics, gneiss, gabbros, granites and pegmatites. Following this discovery, the company is now seeking to expand its licence in the the Nuuk area, and has acquired new landholding in new regions in Western Greenland.
Company Highlights
- Brunswick Exploration (BRW) is a Montreal-based mineral exploration company listed on the TSXV under symbol BRW. The company is focused on grassroots exploration for lithium in Canada and Greenland, a critical metal necessary to global decarbonization and energy transition.
- This has generated one of the largest grassroots lithium portfolios globally.
- BRW's board includes Robert Wares, one of the founders of Osisko Mining.
- BRW was recognized as one of the Top 50 TSX Venture listed companies in 2023.
- The company has staked hundreds of untested prospective pegmatites measuring a minimum strike length of 500 meters and within 50 kilometers of infrastructure.
- In 2023, three discoveries were made in the Eeyou Istchee-James Bay region of Quebec at the Mirage, Anatacau Main and Elrond projects.
- Sirios Resources signed an agreement with Brunswick Exploration granting it the right to purchase a 0.5 percent net smelter return (NSR) held by Sirios on eight claims that are part of Brunswick Exploration's Mirage lithium property located in Eeyou Istchee James Bay.
- In 2024, BRW announced a newly discovered pegmatite outcrop from its Nuuk License making it the first confirmed lithium discovery in Greenland.
Key Projects
Mirage Project
The Mirage project comprises 427 claims with a total surface area of 21,230 hectares (staked and optioned claims), located roughly 40 kilometers south of the Trans-Taiga Highway in Quebec’s James Bay region. Fruitful discussions with a geologist that worked the area twenty- five years ago for gold exploration led to the staking of the BRW claims, as he recorded the presence of several angular pegmatitic glacial boulders hosting well-defined, decimetric spodumene crystals. The largest observed boulder measured 8 meters by 4 meters by 3 meters. In the fall of 2023, BRW discovered several high grade spodumene outcrops over a 2.5 kilometer trend as well as an adjacent 3.0 kilometer spodumene boulder train that has different mineralogy than the discovered outcrops.
In 2023, BRW completed a 5,000-meter drill program at the Mirage project. Phase 1 of the 26- hole program, aimed to test the continuity and widths of the six widest spodumene-bearing pegmatite dykes that have been discovered to date on the property over a total cumulative strike length of 2,500 meters. Final drill results from the 2023 program at the Mirage project have outlined two new spodumene mineralized dykes (MR-5 and MR-6) with significant thickness and grade, all within the Central Zone. MR-23-28 intersected high-grade mineralization of 1.80 percent Li2O over 37.2 meters starting from surface in newly discovered dyke MR-6 located 500 metres northeast of MR-3. Evidence of potential stacking of dykes in Central Zone where MR-23-35 intercepted 11.5 meters grading 1.1 percent Li2O approximately 100 meters south of MR-3 in new dyke MR-5.
In H1 2024, a Phase II drilling campaign, containing 35 holes was completed at the Mirage project by targeting the extensions of known pegmatite dykes (MR-1 to MR-6) while new prospective outcrops have yet to be drill-tested. Results have generated up to 58.10 meters of 1.59 percent Li2O.
In 2024, Brunswick Exploration signed an agreement with Sirios Resources to repurchase an existing 0.5 percent NSR on certain claims within the Mirage project.
Elrond Project
The Elrond Project comprises 136 claims with a total area of 7,048 hectares, located roughly 12 kilometers east of the Billy Diamond Highway in Quebec’s James Bay region. Elrond is part of the Mythril option agreement with Midland Exploration whereby BRW can earn a maximum of 85 percent interest in the project.
In the fall of 2023, BRW uncovered a new, undocumented spodumene-bearing pegmatite, known as the Arwen showing, that is exposed over a surface area measuring approximately 250 meters by 100 meters, dipping very shallowly to the north. The pegmatite remains open in all directions.
The Arwen outcrop is well mineralized in spodumene throughout the showing with an apparent higher-grade zone, containing up to 30 percent spodumene, which has a visible extent of approximately 75 by 15 meters. The spodumene crystals are well formed and up to 30 centimeters in length with an off-white color and were confirmed through LIBS analysis and UV light.
In early 2024, the company completed a maiden drilling campaign at the Elrond project to test the Arwen spodumene-bearing pegmatite. The Arwen pegmatite is well mineralized and three representative grab samples returned values between 1 and 3 percent Li2O. A high-resolution airborne magnetic survey was flown in the fall of 2023 and suggests that the Arwen showing is emplaced in a favorable structural corridor that is 4 kilometers long and 500 meters wide. The target area is proximal to infrastructure, located approximately 12 kilometers from the Billy- Diamond Highway and drilling activities will be ground supported via a winter road.
Anatacau
Comprising the Anatacau Main and Anatacau West projects, these assets are under an option agreement with Osisko GP, a subsidiary of Osisko Development, under which Brunswick Exploration can earn a 90 percent interest in the projects. The Anatacau property is located just east of Arcadium’s (NYSE:ALTM) James Bay Lithium deposit (previously known as the Cyr deposit), which has a total mineral resource of 110.2 million tons (Mt) at 1.30 percent lithium oxide and a total ore reserve of 37.3 Mt at 1.27 percent lithium oxide.
BRW completed a maiden drill program at the Anatacau West property totalling 3,712 meters. 17 of the 18 drilled holes intersected spodumene mineralization that generated up to 26.5 metres at 1.51 percent Li2O.
In the summer of 2023, Brunswick discovered a significant lithium pegmatite outcrop, measuring at least 100 meters long by 15 meters wide known as the Anais showing in Anatacau Main. The outcrop is within a larger cluster of pegmatite dykes all of which contain high-grade lithium mineralization.
This discovery is located 22 kilometers east of Anatacau West and Arcadium’s James Bay project along a large-scale E-W deformation corridor which is host to the known lithium-bearing pegmatite dykes in the region.
BRW reported multiple high spodumene grain countson the Anatacau West property during a till sampling campaign undertaken in the summer of 2024. These highly encouraging results (up to 1,225 spodumene grains in a single sample) further reinforce lithium potential in the bedrock and delineate a new, highly prospective unexplored area at the Anatacau West property beyond the previously drilled pegmatites.
Greenland
Since its confirmation of Greenland’s lithium potential, Brunswick Exploration has a renewed focus on further strengthening its targets in Greenland. The company now controls one of the most significant grassroots exploration portfolios in the country and is the only company actively exploring for lithium in Greenland, according to president and CEO Killian Charles.
Nuuk Expansion
The Nuuk holdings host the new Ivisaartoq discovery within the Ivisaartoq belt. The company has applied to stake the adjacent Ujarassuit amphibolite belt that is up to 1 km in width and roughly 40 km in strike length. The company has also staked additional amphibolite belts within the Fiskefjord Complex, 95 kilometers north of Nuuk, and 75 kilometers southeast of the community of Maniitsoq. These belts are up to 4.5 km in width and 20 km in strike length. In total, the new claims contain hundreds of mapped and interpreted pegmatite outcrops including six that are between 500 and 2,000 meters in strike length for a total license expansion area of 33,138 hectares.
Disko Bay
The Disko Bay licenses are located roughly 30 to 80 km from the coastal city of Ilulissat, which is the third largest city in Greenland. The licenses are near multiple seaports and container terminals, including Ilulissat. The area is situated within the Aasiaat domain, part of the Paleoproterozoic Nagssugtoqidian Orogen, sandwiched to the south by the Archean North Atlantic Craton and to the north by the Archean Rae Craton. The Orogen extends west into the Trans-Hudson orogeny of Canada that continues to the lithium deposits near Snow Lake Manitoba and the Black Hills of South Dakota.
Multiple amphibolite and metasedimentary belts were acquired with some belts being over 20 km in strike length. The new claims have hundreds of mapped and interpreted pegmatite targets with a total license area of 49,639 hectares.
Uummannaq
The licenses are located roughly 70 km from the coastal city of Uummannaq, about 80 km north of Ilulissat. Uummannaq has a population of about 1,660, an airport and a ferry terminal as well as a nearby container terminal. The area is located within the Archean Rae Craton that is intermixed with the Paleoproterozoic Rinkian fold-thrust belt, both of which are in contact with the Paleoproterozoic Nagssugtoqidian Orogen to the south.
The new license contains multiple amphibolite and metasedimentary belts with dozens of mapped and interpreted pegmatites with a total license area of 9,770 hectares.Management Team

Rio Silver
Investor Insight
Rio Silver’s value proposition leverages a wholly owned 4,300 hectares of mineral concessions in a historic Peruvian mining district, a management team holding a 29 percent stake and over two decades of local experience, extensive exploration data and promising historical drill results.
Overview
Rio Silver (TSXV:RYO) is a precious metals mining and exploration company with a focus on the acquisition, exploration and development of precious metals deposits in South America. The company is currently focused on advancing its 100 percent-owned Niñobamba silver-gold project in Peru. The company has decades of experience navigating the mining regulatory landscape of Peru and considers itself to be well-positioned for the coming mining cycle.
Rio Silver’s flagship Niñobamba property is located in the Department of Ayacucho about 330 kilometers southeast of Lima. The 4,300-hectare property is wholly owned by the company and the project is drill ready. The Niñobamba project partially comprises a 2,200 hectare property which was previously owned by Newmont Mining (NYSE:NEM) and Southern Peru Mining. The balance was held by AngloGold Ashanti and Bear Creek Mining but has since been strategically acquired and consolidated into Rio Silver’s property.
The Ninobamba project engulfs a collapsed caldera, an ancient volcano, where the Niñobamba North and South zones were mineralized in a hot spring environment within the wall rock of the caldera surrounded by areas that contain high-sulfidation mineralization with near surface silver and gold deposits modeled for Rio Silver using leapfrog 3D software. The neighbouring Jorimina deposit, 6.5 kilometers to the west, where Newmont spent more than US$7 million, concluded an internal, positive, preliminary economic assessment, detailing a predominantly gold-rich, low to mid-sulfidation deposit found in the floor structure of this collapsed caldera.
The company’s management and advisory team is made up of experienced industry veterans, some with as many as 25 years of experience working in Peru. The team has an in-depth understanding of the regulatory processes associated with mining exploration in the country.
To date, Rio Silver and other historical operators have completed US$10 million in exploration expenditure on the Niñobamba property. The company has low overhead expenditure and strong alliances in Peru that are helping it achieve new initiatives for enhanced sustainability.
The company now holds a 3 percent net smelter return (NSR) royalty with guaranteed minimum payments from a recent property sale and these initiatives enable more exploration by helping Rio Silver with sustaining costs.
Company Highlights
- Rio Silver owns six mineral concessions covering 4,300 hectares of wholly-owned land in a historic Peruvian mining district.
- The property was historically surrounded by big-name miners (Newmont, Southern Peru Copper) and is now wholly owned by Rio Silver.
- Experienced management team with more than two decades of mining experience in Peru.
- Extensive trenching completed at the Niñobamba zone.
- The management team holds a 29 percent stake in the company.
- US$10 million in exploration expenditure completed to date by Rio and historical operators.
- All the historical data has been collected from previous owners.
- Historical drilling on the Niñobamba property intersected 130 meters of 2.55 oz/t silver and 72.3 meters of 1.19 g/t gold.
- New gold zone identified include 56 meters at 98.9 g/t silver and 21.77 meters at 1.32 g/t gold, 102.46 g/t silver.
Key Project
Niñobamba Silver Project, Peru
Located 330 kilometers southeast of Lima in the Department of Ayacucho, the Niñobamba property is 100 percent wholly owned by Rio Silver. The property includes six mineral concessions covering 4,300 hectares. The district has historically been mined by major international gold miners including Newmont Goldcorp and Southern Peru Mining.
The property was initially explored by AngloGold (JSE:ANG) in 2001. Anglo drilled five widely-spaced core holes totaling 861 meters focusing in an area of intense hydrothermal surface alteration. AngloGold’s drilling highlights included assay results of 87.0 grams per tonne (g/t) silver over a drilled interval of 130 meters starting from a depth of 9 meters reported from drill hole DDH-2 and 54.0 g/t silver over a drilled interval of 96 meters starting from 23 meters reported from the AN-04 drill hole.
Adjacent zones acquired from major miners
In 2016, Rio Silver consolidated its property by acquiring the surrounding 2,200 hectares of adjoining land from Newmont Mining and Southern Peru Copper. These included the 2,000 hectare Jorimina zone, which is located about 6.5 kilometers west of the Niñobamba and is believed to be part of the same high-sulfidation silver-gold system identified in the main Niñobamba zones. Along with the property came an extensive database of information including results and reports from an exploration program by the mining majors which encompassed 553 hectares. Newmont’s exploration included mapping, 2,147 rock samples and induced polarization geophysics. This historic exploration indicated a gold anomalous area of more than 700 meters by 1,000 meters as well as four strong chargeability anomalies coinciding with gold-silver in rock anomalies.
Newmont’s historic data includes samples of 17.4 meters of 3.06 g/t gold and 200 meters of 0.26 g/t gold. Historic exploration in the Jorimina zone conducted by Newmont in 2009 and 2010 shows highlights of 72.3 meters of 1.19 g/t gold starting at 53-meter depth.
In 2024, Rio Silver completed a surface access agreement with the local community for one year at the Jorimina project after an environmental impact study and community workshops were also completed to represent the final steps of the drill permitting application process.
Exploration and trenching results
To date, extensive trenching has been completed by Rio Silver on the Niñobamba property. In 2012, the company began conducting surface trenching in areas proximate to historical drilling locations. Exploration has focused primarily on the north and south zones of silver mineralization approximately 400 meters apart with variable thicknesses. Surface sampling near trenches in the north zone returned highlights of 1.32 g/t gold and 102.46 g/t silver. Sampling near trenches in the south zone returned highlights of 42.62 meters of 130.98 g/t silver. Additional highlights can be found on Rio Silver’s website.Management Team
