  Bishop Gold Mill Operations  

 

Gold concentrate shipments in April, 2025 to the Company's refinery partner Just Refiners, Reno, NV totaled 667 wet lbs. These are the second and third gold concentrate test shipments from the Bishop Gold Mill. Approximately 8 and 4 gross tons were processed for shipments #2 and #3 with an average recovered grade of 0.08 and 0.11 ounces per ton respectively reflecting a per ton value of $260 and $360 per ton. The low value per ton of the 2 nd shipment reflected a breakdown period of the raker/classifier where heavy and inconsistent grind size occurred. Upgrades and repairs were made to the raker/classifier throughout the month of April including removal and hot welding of the attenuator and fabrication and installation of a new control arm. This resulted in a greatly increased consistency and reduction in size of material feed to the centrifuge and marked improvement in produced gold per ton between shipment #2 and #3 reflecting the upgrades and return to recovery within 10% of shipment #1. Final optimization is being made to increase grind size from 150-200 US Mesh to 80-100 US Mesh to further increase recovery. The upgrades to the raker/classifier may have resulted in overgrinding and this final optimization of size and targeted total dissolved solids percentage of 30% is underway. Implementation of the drying circuit reduced moisture content by 60% from 16.20% between shipment #2 and shipment #3. Focus remains ramp-up in preparation for increased deliveries of 100 tons per week in the short term and full commercial production of 100 tons per day thereafter.

 

Flotation circuit design has been finalized and an additional mixing tank is being added to augment the flotation circuit. The new mixing tank will be used for the addition of gold and sulphide promoter where slurry resides prior to the addition of frother and flow to the flotation cells. The reagents provide a hydrophobic response to the water and rise on the air bubbles where the gold is pushed by rotating paddles from the surface of the cells into a concentrate collector. The concentrate is then re-circulated through the centrifuge to produce a high grade concentrate for shipment to the Company's refinery partner for gold sale. Metallurgical testing has shown a high affinity for flotation and significant additional recovery of fine gold is anticipated.

 

  Fran Gold Mobilization  

 

Mobilization for development at Fran Gold is underway and crews will be on-site in early June. Work will consist of exploration for further development and preparation for additional shipments of ore from existing stockpiles throughout the Summer. The Company will implement grade control on the stockpiles to increase per tonnage value and maximize head grade at the mill, while providing sufficient ore for continuous throughput. In preparation for mining, once stockpiles are depleted, the Company will focus in and around surface trenches B + C as well as trench A. Trenches B + C have shown consistent grade of 0.5 ounces per ton over 30 meters (100 feet).

 

  Fran Gold Project  

 

As a result of the recently discovered bulk tonnage deposit and associated resource estimate ( see Press Release dated May 13, 2025 ), the Company has implemented a two-pronged approach to the Fran Gold Project,   In addition to providing feedstock to the Company's Bishop Gold Mill from stockpiles and the high grade surface oxide zone, exploration will now occur in the infill area between the Main Bullion Alley Zone and East Zone as well as further to the East and North-east and at a number of other known discoveries on the property Re-analyses of Au soil grids has shown a number of anomalies within or in close proximity to the Main and East Zones showing both gold and, of particular note a significant increase in copper grade, in a NE trending direction. A very large geological intrusion exists and geomagnetic halo exists to the East, common with porphyry style deposits, along with the noted increase in base metal grades with gold. The goal is to further expand the known mineralized zone with current resource estimate ( non-NI 43-101) as follows:

 
                 
Bullion Alley - Main Zone
    
  Mass  
(tonnes)  
  Average (g/t)    Total  
(grams)  
  Total  
(tr. ounces)  
20,035,146 0.50 10,051,730 323,170
    
 

 

 
                     
Bullion Alley - Main Zone + East Extension
    
  Mass  
(tonnes)  
  Average  
(g/t)  
  Total  
(grams)  
  Total  
(tr. ounces)  
43,797,234 0.34 14,743,070 474,001
    
    
 

Using a gold price of $3,100 per ounce, gross value in the Main Zone is estimated at $50 per tonne. Mining costs at the nearby Blackwater Gold Mine are $9 per tonne processed. As a result, the Company is proceeding with the development of the bulk tonnage deposit and has begun consultation with Mine Engineering firms regarding detailed economics, mine plan, and development.

 

Past exploration and development, including over 18,000m (55,000ft.) of diamond drilling, has shown large intercepts of mixed vein and disseminated gold. The deposit area has been identified to be in excess of 1000m x 100m x 300m within a known strike length of 1700m. The Fran Gold Project is next to Centerra Gold's Mt. Milligan Project, with Reserves of 264Mt grading 0.3 gram per tonne gold and 0.2% copper and proximate to Artemis Gold's Blackwater Mine, with Proven and Probable Reserves of 334Mt grading 0.8 grams per tonne gold. Both Mt. Milligan and the Blackwater Mine are two of the largest new copper/gold and gold mines respectively, in North America.

Walker Lane Resources Ltd. Notes Unusual Trading Activity and the Development of its New Website

Walker Lane Resources Ltd. (TSX-V: WLR, “Walker Lane”) announces that there has been unusual trading activity of its common shares that appeared to initiate on March 27, 2025 and appears to have occurred on each subsequent TSX-V trading day to current day. The recent stock trading activity does not reflect the health of our business or the recent significant value added assets to the property portfolio and adds to the previous undervaluation of the assets that were noted in a research report completed by Fundamental Research Corporation (see CMC Metals Ltd. press release - January 15, 2025). Management considers that some recent market transactions of its common shares could be an organized type of short selling tactic as we cannot determine any other explanation for the unusual downside trading activity.

Top 5 Australian Mining Stocks This Week: Yandal Shares Double on Arrakis Drilling Results

Welcome to the Investing News Network's weekly round-up of Australia’s top-performing mining stocks on the ASX, starting with news in Australia's resource sector.

This week's top-performing stocks list is dominated by oil and gas companies, alongside gold and lithium companies.

In Australian mining news, the Fair Work Commission ruled that BHP (ASX:BHP,NYSE:BHP,LSE:BHP) must raise the wages of 2,200 workers at three coal mines in Queensland. The workers in question were employed indirectly through a hiring firm and were being paid significantly less than their peers working directly under BHP.

The case was brought by two worker's unions and based on the Same Job, Same Pay reforms made by the government last year. To align wages, the FWC ruled BHP must raise the labour hire employees' wages by AU$30,000 each.

Pilbara 2.0: Inside Australia’s Newest Gold Frontier

The Central Pilbara region of Western Australia is undergoing a quiet revolution that is rapidly reshaping the global gold exploration landscape.

Once dismissed as a technically challenging and geologically inconsistent terrain, Pilbara is now emerging as one of the world’s most exciting new gold frontiers and drawing serious attention from institutional investors, driven by transformative discoveries, a maturing geological model and a wave of junior explorers tapping into underexplored intrusive-hosted systems.

Anchored by the multimillion-ounce Hemi discovery — one of the most significant gold finds in Australia in over a decade — this region is not just proving its geological potential, but also demonstrating the kind of scale, consistency and margin profile that modern gold investors seek. As the discovery window remains wide open and valuations are still accessible, the Central Pilbara presents a rare opportunity for early exposure to what may become one of Australia’s next tier-one gold districts.
