Empire Copper Gold Project Previous exploration activity at Empire including drilling and soil geochemistry prove a very strong geochemical signature in the associate elements of Au-Ag-Bi-Cu-Mo-Sb-W typical of copper-gold porphyry systems. So far drilling has focussed only on the stockworks where an open pit mineable resource has been defined. Our latest rock chips show these stockworks extend for at least another 750m and our geologist believes these could be the part of a bigger porphyry style target.

Investor Insight
Far Northern Resources is well-placed to capitalize on Australia's resource opportunities and deliver sustainable returns to its shareholders as it pursues strategic exploration across its assets in some of Australia’s most prolific mining jurisdictions.
Overview
Far Northern Resources (ASX:FNR) is a newly listed Australian explorer focused on gold and base metals. The company debuted on the ASX on April 12, 2024, after finalizing its IPO, during which it secured AU$4 million in funding. The company has three exploration projects – two based in Northern Queensland (Empire and Rocks Reef) and one in the Northern Territories (Bridge Creek).
In the 2022-23 fiscal year, mining played a pivotal role in Australia's economy by generating a record $455 billion in export revenue, accounting for nearly 66 percent of the total exports. This underscores the industry's significant contribution to the nation's economic stability, government revenues, and the creation of employment opportunities in regional areas.
According to the Fraser Institute Annual Survey of Mining Companies 2023, Australia is one of the most attractive regions for mining. Fraser Institute ranks the Northern Territories and Queensland as the 6th and 13th most attractive destinations for mining investment.
During 2023, Queensland's mines yielded 12.6 tons of gold, positioning it as the fourth most prolific state in Australia for this precious metal. Its output falls slightly below that of the Northern Territory (13.9 tons).
Its presence in relatively attractive mining jurisdictions positions the company to capitalize on opportunities in Australia's resource sector and deliver sustainable returns to its shareholders. The IPO funds of AU$4 million have provided sufficient funding to the company to advance its exploration projects. Overall, Far Northern is planning a 20,000-meter drilling program over the next two years, which will consist: of over 5,000 meters for Empire; 2,500 to 5,000 meters for Bridge Creek; and 2,500 meters planned at Rocks Reef in the China Wall prospect.
Company Highlights
- Far Northern Resources (FNR) is a newly listed Australia-based gold and base metals exploration company. The company was listed on the ASX on April 12, 2024, following the completion of its IPO in which it raised AU$4 million.
- The company has three projects across Northern Queensland and the Northern Territories – Empire, Bridge Creek and Rocks Reef. Empire and Bridge Creek are significantly advanced, drill-ready with JORC-compliant resources.
- The flagship project Empire has undergone extensive exploration work culminating in a 2019 mineral resource estimate of 22,500 oz gold.
- At Bridge Creek, FNR is planning a drilling program, which aims to move inferred resources to indicated status, as well as extend the mineralization both along the strike and at depth.
- The Rock Reefs property presents a prospective upside for FNR with historical exploration showing promise for gold and copper mineralization.
- The presence in relatively attractive mining jurisdictions in Australia positions the company to capitalize on opportunities in Australia's resource sector and deliver superior returns to its shareholders.
Key Projects
Empire Project (Copper-Gold)
The Empire Project, situated 34 km west of the mining town of Chillagoe in North Queensland which had a mill for treating locally mined ore. The project covers an expansive 252 hectares on a granted mining lease. The tenement boasts a rich exploration history, marked by substantial drilling conducted across various phases. This culminated in the determination of a 2019 mineral resource estimate of 22,505 oz of gold on the Empire Stockworks gold deposit.
More than 7,460 meters of RC drilling and 750 meters of diamond core drilling have been carried out by Far Northern Resources, resulting in multiple intersections of copper, gold and silver. Rock chip assays yielded noteworthy grades, with results showing up to 12.64 percent copper (FNRRCS24001) and 4.12 grams per ton (g/t) gold (FNRRCS24002). Further surface sampling unveiled copper grades ranging from 2.61 percent to 11.89 percent and gold grades from 0.70 g/t to 2.16 g/t.
The rock chip assays extended the strike of known mineralization at the Empire Stockworks prospect by a further 750 meters and management believes it could be part of a bigger porphyry-style target.
The company is in the process of updating its current resource and block model before returning to site in 2025 to continue exploration.
Several targets have already been identified on the Empire tenement:
Empire Stockworks Prospect: Located close to the northern Breccia zone, this is the most advanced Far Northern target, in respect of exploration progress.
FNR has completed an RC drilling program at the Empire Gold Deposit designed to update and infill the 2020 resource model drilling program at the Empire Mining Lease. The program confirmed the presence of a zone in the primary vein at the northern end of the Empire Stockworks consisting of a high-grade gold zone within the greater Empire Stockworks gold system, with mineralisation open at depth and along strike. Assays from all six drill holes intercepted the high-grade quartz veins that formed the basis of the previous modeling. These results will provide further data on the known resources at the Empire Stockwork that will enable FNR to update the resource and economic modelling at the current gold prices, to move into future feasibility studies.
United Empire: Situated south of the Empire Stockworks prospect and adjacent to the Pinnacles breccia zone, this anomaly exhibits copper/gold characteristics, as revealed by previous exploration efforts conducted by entities other than Far Northern.
Copper Pit: It is also located south of the Empire Stockworks prospect and close to Pinnacles breccia. The analysis of the minor mullock heaps in the vicinity suggests the area holds promise for copper and gold prospects.
Pinnacles Prospect: It is situated in the Pinnacles breccia zone to the south of the Empire Stockworks Prospect. Far Northern has done very minimal exploration work so far on this prospect.
Bridge Creek Project (primarily Gold)
The project is located 150 km south of Darwin in the Northern Territories. It comprises three mining leases situated within the Pine Creek Geosyncline. The project is in the historical mining area of Cosmos Howley – Pine Creek which has produced over 2 million oz of gold. It covers a sector of the axis of the Howley Anticline, approximately 12 km along strike north from the Cosmopolitan Howley gold mine currently owned by Kirkland Lake Gold.
A mineral resource estimate was completed in 2022 containing 70,560 oz of inferred gold resources.
Far Northern is looking to accelerate its exploration activity at Bridge Creek, with a planned 2,500 to 5,000-meter drilling program in 2025, aiming to move the inferred resources to indicated status, as well as extend the mineralization both along the strike and at depth.
Rocks Reef Project (Copper-Gold)
The Rocks Reef Project is located 52 km west of Chillagoe and comprises exploration permit 26473, which covers the Georgetown Tectonic Province. It is situated along a northeast structural trend spanning over 20 kilometers, within a large quartz-veined and altered porphyry formation. Geochemical sampling has revealed anomalous gold and silver veins within a 3-km by 1-km area.
The Rock Reefs property presents a prospective upside for Far Northern with historical exploration confirming the presence of a mineralized vein system at the China Wall prospect. The project shows early-stage promise for gold and copper deposits. Far Northern has completed an extensive early exploration program and results are expected over the coming months.
FNR has already identified targets for the tenement:
China Wall: Situated north of the tenement, this represents the most advanced target in terms of exploration progress within Rocks Reef. The previous operator had drilled a total of 155 air track holes along major and minor epithermal veins and structures, reporting precious metal mineralization. Subsequently, Far Northern conducted rock chip and soil analyses as part of follow-up investigations. Management is now planning a 2,500-meter drill program at the China Wall prospect.
Savannah Way and Single Peak: It is located about 1.3 km north of the China Wall. Far Northern has undertaken a rock chip and soil sampling program.
Roadside Copper: The target is located about 4.5 km from the China Wall Prospect. It saw little exploration work when it was held by the previous owner. Far Northern has conducted preliminary exploration including the analysis of rock chips and soils, which revealed the presence of gold, copper and associated minerals in the area.
North Drift Breccia and South Drift: Here again, the rock chip and soil samples have returned positive results indicating potential for mineralization.

Ore Purchase Agreement with Westgold Resources Unlocks Gold Production from Crown Prince
HIGHLIGHTS
- New Murchison Gold (NMG) and Westgold Resources (Westgold) have entered into an Ore Purchase Agreement (OPA) which will underpin production from NMG’s Crown Prince deposit near Meekatharra, Western Australia in 2025.
- Subject to final regulatory permitting, under the OPA, NMG will commence mining from a new open pit operation at Crown Prince with a targeted commencement date of mid-2025.
- Ore will be hauled 33km by road to the Bluebird Gold Processing Plant, part of Westgold’s Murchison Gold Operations at Meekatharra.
- Ore will be sold to Westgold in several parcels (Ore Parcels) totalling 30-50kt per month with each Ore Parcel certified for grade, moisture and recovery from sampling at the Crown Prince site and a recovery factor agreed for each mining bench from test work replicating the Bluebird Mill circuit.
- The OPA has no fixed term although NMG envisages that most of Crown Prince ore is likely to be processed in an “Initial Period” which runs over the first 24 months of the agreement. Thereafter ore tonnages are to be agreed on a rolling three-month basis once production forecasts have been completed by NMG and Westgold has confirmed mill availability.
- Westgold will purchase ore from NMG based on contained gold in each Ore Parcel at the prevailing AUD gold price in the month the Ore Parcel is collected (minus processing costs and a capital recovery charge). Westgold must promptly collect Ore Parcels that are available for collection.
- The OPA is subject to shareholder approval (Listing Rule 10.1 requirement) at a general meeting of NMG shareholders to be held in late January or early February 2025.
- NMG and Westgold have also entered into an ancillary agreement (Licence and Access Water Discharge Deed) which facilitates NMG’s potential dewatering requirements at Crown Prince.
Alex Passmore, NMG’s CEO commented: "We are very pleased to announce the Ore Purchase Agreement with Westgold as it sees both companies working together to support the development of NMG’s Crown Prince deposit in a capitally efficient manner.
We see this Agreement as beneficial to all shareholders with Westgold acquiring additional high grade oxide ore feed to supplement its Meekatharra operations and NMG transitioning to a producer for modest capital.
The Bluebird Processing Plant owned by Westgold is ideal for NMG due to its close proximity and well-matched metallurgical process. We believe the robust frameworks and protocols we have put in place in this Agreement aligns both operational teams to a common goal of maximizing operational efficiency.
We thank the Westgold team for the technical and commercial work that has led to this Agreement and look forward to working collaboratively in making the development of Crown Prince a success”
Crown Prince is located to the north of Meekatharra, around 33km via road to the Bluebird Gold Processing Plant (Bluebird) owned and operated by BBGO. Westgold and NMG have been working collaboratively on the OPA to manage technical risks and to share economic synergies which are available via the partnering of production from the Crown Prince deposit and milling at Bluebird.
Key Terms of the OPA are outlined in the Table below and will be explained fully in a Notice of Meeting to be sent to NMG shareholders in December. The NMG shareholder meeting is likely to be held in late January or early February 2025. As a result of Westgold’s 18.7% ownership of NMG, it is deemed a related party under the ASX Listing Rules and so the OPA includes a condition precedent of NMG obtaining shareholder approval under Listing Rule 10.1.
BDO Corporate Finance Australia Pty Ltd (BDO) has been engaged to provide an opinion and Independent Expert’s Report to accompany the Notice of Meeting to assist shareholders in their considerations of whether or not to approve the OPA moving into operation.
Should the conditions precedent be met (shareholder approval) the OPA will come into effect with NMG expecting mining approvals to be received in early April 2025. Once mining operations commence, and ore stockpiles are built up, it is anticipated that first Ore Parcel sales will occur in September 2025.
The company is working towards an ore reserve estimate to provide further detail on the economics of the project which is to be released shortly.

Lahontan Gold Announces Positive Preliminary Economic Assessment for Santa Fe
Lahontan Gold Corp. (TSXV:LG)(OTCQB:LGCXF)(the "Company" or "Lahontan") is pleased to announce results from a positive Preliminary Economic Assessment(" PEA") on its flagship Santa Fe Mine gold-silver project located in Nevada's prolific Walker Lane Trend. The PEA was prepared by Kappes, Cassiday & Associates ("KCA") of Reno, Nevada with mine planning and production scheduling contributions from RESPEC Company LLC ("Respec"), Reno, Nevada and mineral resource estimation by Equity Exploration Consultants Ltd. ("Equity"), of Vancouver, British Columbia, in accordance with Canadian National Instrument 43-101, Standards of Disclosure for Mineral Projects ("NI 43-101").
PEA Highlights:
- Pre-tax Net Present Value at a 5% discount rate ("NPV5") of US$265.1 M with a 41.0% IRRwith an After-tax NPV5 of US$200.0 M with a 34.2% IRR utilizing a $2,705/oz gold price and a $32.60/oz silver price ("spot metal prices") (see spot metal price to base case metal price comparison in Table 1).
- Total Life-of-Mine ("LOM") Pre-tax net cash flow of US$373.3 M and After-tax net cash flow of US$288.9 M over a nine-year project life using spot metal prices.
- Total projected LOM revenue of US$930.8 M over a nine-year project life using spot metal prices.
- LOM strip ratio of only 1.54 (waste to mineralized material ratio).
- Estimated pre-production capital costs of US$135.1 M including a 20% contingency, with a payback of 2.9 years using spot metal prices.
Kimberly Ann, Lahontan Gold Corp Executive Chair, CEO, President, and Founder commented: "Lahontan is very excited about the results of the PEA: a low-capex, highly profitable mining project with a quick payback certainly bodes well for the future of Lahontan and all stakeholders. There is considerable potential to expand gold and silver resources, therefore this is just the first step in restarting mining operations at Santa Fe. With mine permitting well under-way, targeting a 2026 mine ground-breaking, the potential for the Company to realize the economic outcomes outlined in the PEA is very real, especially given current trends in gold and silver prices. Continued optimization of the mine plan, resource expansion drilling, and refining the metallurgical flow sheet are planned for 2025, in parallel with our permitting activities."
The PEA is preliminary in nature, includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The Company has not defined any Mineral Reserves at the Santa Fe Mine project.

Capital Costs
Capital costs for the project are summarized in Table 2. Capital costs associated with the mining operation were estimated by RESPEC and based on mining by contractor. Pre-stripping costs were based on the operating costs discussed below. Capital costs associated with processing such as crushing, heap leaching and metal recovery, along with support and infrastructure costs associated with laboratory, water and power distribution and general site services were estimated by KCA. Reclamation and closure costs of $12.5 M were estimated by KCA.

(1) Values are rounded and may not sum perfectly
Mine Production Schedule
The PEA mine production schedule includes mining of leach material and waste for the Santa Fe, Calvada, Slab, and York deposits. Leach material was assumed to be sent to a centralized crushing plant and then stacked on a leach pad and the waste material was sent to designed waste rock storage facilities (WRSF) or used as partial backfill into the Calvada pit.
Because the Santa Fe Mine is a brown-field project, minimal pre-stripping is required to develop sufficient stockpiles to feed the crusher. The mine production schedule requires 2 months of preproduction which begins in the Santa Fe deposit. The Calvada deposit is started in year 2 and mined concurrently with Santa Fe. Calvada mining is followed by mining of Slab and York deposits.
The process schedule was developed with a ramp up of production from year 1 through year 3 to a full 4.56 million tonnes per year. Table 4 shows the process production schedule.

Mining and Processing
The mineralized material will be mined by standard open-pit mining methods using a contractor-owned and operated mining fleet consisting of 92-tonne haul trucks and 11.5-m3 loading units and transported to the crushing circuit for processing.
Mineralized material from the Santa Fe, Calvada, Slab and York deposits will be processed by conventional heap leaching methods. The nominal processing rate will be 4.6 million tonnes per annum or 12,500 tonnes per day. Three-stage crushing of the material to 12.7 mm, will be followed by conveyor stacking on to a multi-lift heap leach pad. Dilute sodium cyanide solution will be applied to the heap, with the pregnant gold and silver-bearing solution effluent from the heap being processed in a carbon adsorption-desorption-recovery (ADR) plant. Gold and silver will be produced in the form of doré bars from the on-site smelting process.
Mineral Resource Estimation
The mineral resource estimate ("MRE") was prepared in accordance with the CIM Definition Standards and Canadian National Instrument NI-43-101. The effective date of the MRE prepared by Equity is October 9, 2024. The MRE is shown in Table 6.
Table 6: Project-wide Resources, Santa Fe Mine, Mineral County, Nevada
Notes to Table 6:
- Mineral Resources have an effective date of October 9, 2024. The Mineral Resource Estimate for the Santa Fe Mine was prepared by Trevor Rabb, P.Geo., of Equity Exploration Consultants Ltd., an independent Qualified Person as defined by NI 43-101.
- Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Inferred Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be classified as Mineral Reserves. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
- Resources are reported in accordance with NI43-101 Standards of Disclosure for Mineral Projects (BCSC, 2016) and the CIM Definition Standards for Mineral Resources and Mineral Reserves (CIM, 2014).
- Mineral Resources were estimated for gold, silver, and gold equivalent (Au Eq) using a combination of ordinary kriging and inverse distance cubed within grade shell domains.
- Mineral resources are reported using a cut-off grade of 0.15 g/t Au Eq for oxide resources and 0.60 g/t Au Eq for non-oxide resources. Au Eq for the purpose of cut-off grade and reporting the Mineral Resources is based on the following assumptions gold price of US$1,950/oz gold, silver price of US$23.50/oz silver, and oxide gold recoveries ranging from 45% to 79%, oxide silver recoveries ranging from 10% to 30%, and non-oxide gold and silver recoveries of 71%, mining costs for resource and waste of US$2.50/t, processing cost (oxide) US$3.49/t, processing cost (non-oxide) US$25/t.
- An optimized open-pit shell was used to constrain the Mineral Resource and was generated using Lerchs-Grossman algorithm utilizing the following parameters: gold price of US$1,950/oz gold, silver price of US$23.50/oz silver, and selling costs of US$29.25/oz gold. Mining costs for resource and waste of US$2.50/t, processing cost (oxide) US$3.49/t, processing cost (non-oxide) US$25/t, G&A cost US$1.06/t. Royalties for the Slab, York and Calvada deposits are 1.25%, and maximum pit slope angles of 50 degrees.
- Totals may not sum due to rounding.
Estimation Approach: Lithology and gold and silver bearing domains were modelled using Leapfrog 2024. These domains are mainly defined by logged jasperoid and limestone-breccia lithologies and continuity of gold grades above 0.1 g/t gold. Metallurgical domains for oxide, transition and non-oxide were modelled based on ratio of cyanide leachable gold assay values to fire assay gold values in addition to drillhole logs recording abundance of pyrite and oxidation intensity. Transition material represents approximately 35% of oxide tonnes and comes almost entirely from the Santa Fe deposit. Transition domain material is included in the oxide resource. Domains representing lithology, weathering and mineralization models were assigned to a block model with a block size of 5 m x 5 m x 6 m. Average bulk densities representative of the mineralization and lithology models were assigned to the block model and vary from 2.4 t/m3 to 2.6 t/m3.
Grade capping and outlier restrictions were applied to gold and silver values and interpolation parameters respectively. Top cut values for gold and silver were evaluated for each domain independently prior to compositing to 1.52 m lengths that honor domain boundaries. Estimation was completed using Micromine Origin with Ordinary Kriging (OK) and Inverse Distance cubed (ID3) interpolants. Blocks were classified in accordance with the 2014 CIM Definition Standards. The nominal drillhole spacing for Indicated Mineral Resources is 50 m or less. The nominal drillhole spacing for Inferred Mineral Resources is 100 m or less.
Prospects for eventual economic extraction were evaluated by performing pit optimization using Lerchs-Grossman algorithm with the following parameters: gold price of US$1,950/oz gold, silver price of US$23.50/oz silver, selling costs of US$29.25/oz gold. Mining costs for resource and waste of US$2.50/t, processing cost (oxide) US$3.49/t, processing cost (non-oxide) US$25/t, G&A cost US$1.06/t. Royalties for the Slab, York and Calvada deposits are 1.25%. Maximum pit slope is 50 degrees. Processing recoveries range from 45% to 79% for oxide, silver recoveries range from 10% to 30% for oxide and non-oxide gold and silver recoveries are 71%.
