Rio Silver
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 3,933-hectare property is wholly owned by the company and the project is drill ready. The Niñobamba project is partially comprised of 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 an a colaped caldera, an anchient 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 leapfrod 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.
Rio Silver is currently working on additional silver-focused initiatives, yet to be announced and the company has achieved social license and has successfully completed an access agreement at Jorimina with immediate plans to expand on the successful internal preliminary economic assessment (PEA), conducted by Newmont in 2012 through a diamond drilling campaign in Q3 2024 to delineate this resource.
Company Highlights
- Rio Silver owns six mineral concessions covering 4,100 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.

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 6 mineral concessions covering 3,933 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 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.
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.

Kirgella Gift and Providence: First Inferred Mineral Resource Estimate of 76,400 oz Au from only 3m depth
Highlights
- First Inferred Mineral Resource Estimate for Kirgella Gift and Providence of: 2.34 Mt @ 1.0 g/t Au for 76,400 oz at a 0.5 g/t gold cut-off from only 3m depth.
- Gold mineralisation remains open at depth and along strike between Kirgella Gift and Providence:
- Potential for significant resource growth and upgrade following additional drilling to expand on unclassified blocks outside current model limits.
- Highly economic discovery with KalGold’s direct exploration expenditure cost (drilling and assay) of only ~A$4.20 per gold ounce.
- KalGold’s Total Mineral Resource base, comprising this new resource from the Pinjin Project, and the La Mascotte deposit at Bulong Taurus (see ASX: KAL 7th March 2023), now stands at 214,300 oz.
- Elevated gold price of over A$3,600/oz continues to drive interest in mineable gold projects.
KalGold Managing Director and CEO Matt Painter said:
“KalGold is proud to report the first Mineral Resource Estimate at the Kirgella Gift and Providence gold deposits. It totals ~76,000 oz defined at over 1.0 g/t Au from only 3m depth, remains open in several directions, and is considered the first step in defining the full potential of the Kirgella Gift and Providence gold deposits. Pleasingly, we have defined a shallow gold resource at a very low cost to the Company of around A$4.20 per gold ounce.
The Kirgella and Providence mineral resource estimate is comparable to other deposits within the Laverton Tectonic Zone and is considered typical of the region. This is particularly true of some of the constituent deposits at Ramelius Resources’ (ASX:RMS) Rebecca Gold Project, around 20 km to the south along strike.
KalGold now has defined a total resource base of 214,300 oz of gold. The increased resource base enables KalGold to commence high level mining optimisation studies to assess pathways to production. KalGold looks forward to continuing to progress its work in the Pinjin area with the aim of significantly growing this initial JORC Code (2012) resource and defining a suite of additional shallow resources.”
First Gold MRE at KalGold’s Pinjin Project
The Inferred MRE of 2.34 Mt @ 1.0 g/t Au for 76,400 oz Au has been defined at a 0.5 g/t gold cut-off from the Company’s recent drill focus on the shallow portion of the Kirgella Gift and adjacent Providence gold deposits (see Table 1), combined with thoroughly validated historic datasets. Work continues on both deposits, with gold mineralisation open at depth and along strike between the two. This MRE is expected to form the basis of future updates as drilling and exploration continues.

Acquisition of Mubende Gold Project, Uganda
HIGHLIGHTS
- The granted exploration license EL00379 covers 202 square kilometres in the Mubende region west of Kampala and includes the highly prospective Bukuya prospect.
- The Bukuya prospect is currently being mined by 60-80 artisanal workers over 600 metres of prospective strike and remains open along strike and at depth.
- Rock chip samples taken from a recent site visit to the Bukuya prospect by consultant geologists returned numerous specimens containing visible gold in both ferro-manganese and quartz veins.
- Experienced in-country technical team appointed including Mr Dylan le Roux and Mr Allan Agumya to manage exploration activities.
- Field activities scheduled to commence 05 August 2024.
Commenting on the acquisition Managing Director Mr Mathew Walker stated, “We are delighted to have secured a significant land holding that has prospectivity confirmed by a strong presence of artisanal mining activity. Uganda has a well established gold mining industry and regulatory protocols that add to the appeal of the acquisition. We look forward to the commencement of field activities in the immediate term.”
MUBENDE GOLD PROJECT
The Mubende Gold Project is an extensive landholding of 202 square kilometers that covers a series of metasediments, predominantly characterized by meta-wacke’s and phyllitic slates, with occasional interbedded quartzite units and mafic volcanics. Late-stage granites have intruded the metasediments, mainly in the southern part of the license.
Figure 1: Regional Map with locations of Sifang licenses.
At the Bukuya prospect, wall rock consists of metapelitic units with vertical foliation trending NW in most shafts, turning EW in the northern artisanal shafts. Mineralization appears confined to a deformation zone within the metapelites and hosts three subsets of veins exploited by artisanal workers. The first subset includes quartz veins with hematite mineralization, iron-oxide staining, and goethite/limonite-filled vugs, seen in southern shafts with NW trending foliation. The second subset comprises metallic veins of blueish-grey and black ferro-manganese mineralisation with botryoidal textures and specular hematite, found in northern shafts with EW trending foliation. The third set comprises massive milky white quartz veins.
These veins are described in more detail below.
Type 1 (Iron-rich quartz veins): These are quartz veins that show varying degrees of ferro(-manganese) mineralisation. Mineralisation occurs as hematite (red), specular hematite (dark silver/black), and a lesser degree of manganese (botryoidal, blue-grey to black). Vugs filled with limonitic material is often seen in these veins and is interpreted to represent leached out sulphides. These veins are seen in the SE of the Bukuya site. They are typically decimetre to metre scale and are foliation concordant (vertical to subvertical with dominantly NW trend).
