Sierra Nevada Gold (ASX: SNX) is pleased to announce it is preparing a drilling program to follow up drill hole BHD006 which returned results including 0.5m at 1,270 g/t Ag and 1m at 823g/t Ag at Endowment Mine, part of its Blackhawk Epithermal project in Nevada, USA.1
Highlights
- SNX plans seven-hole 1,500m reverse circulation (RC) drill program to follow up on drillhole BHD006, which was drilled beneath the historic Endowment Mine.
- High-grade silver intercepts are associated with very high-grade lead-zinc (see table 1), demonstrating potential for extremely high value ore at Blackhawk Epithermal Project.
- SNX’s geological team will initiate a field program to complete geological mapping, soil geochemistry surveys and rock chip sampling on vein target areas, to further refine drill targets in preparation for drilling in the third quarter of 2024.
- Underground 3D scanning survey of accessible historic workings at the Endowment Mine will map extent and location of historic workings to accurately target planned drill holes following up on drill hole BHD006.
- SNX will initiate a focused, 100m dipole-spaced Induced Polarization (IP) geophysics survey over preferred portions of the vein field to assist with drill hole targeting.
- Blackhawk epithermal project has potential for a significant silver discovery, with 22.5- line kilometres of high-grade silver-gold-lead-zinc veins identified1.
- SNX completed a $2.6 million capital raising in May 2024 to advance exploration at Blackhawk epithermal project.2
- It has commenced a strategic review to progress full or partial asset sales or joint venture partnerships over remaining copper, gold and silver assets in Nevada, USA.
SNX Executive Chairman Peter Moore said “We were encouraged by the strong support for our recent $2.6 million share placement and proceeds from this will allow the company to accelerate our exploration program at Blackhawk as we look to uncover its potential to be a significant silver discovery. We have several activities planned to ensure our drill targets are well defined ahead of mobilising a rig to site in Q3 2024 to follow up these exciting earlier silver results.”
SNX has identified a large and high-grade intermediate sulphidation polymetallic epithermal Ag-Au-Pb-Zn vein system at Blackhawk, which is related to a large porphyry system. Partially coincident with, and located north of the Blackhawk Porphyry system, the vein field covers about 5km2 and is open under cover to the north and northeast, with 22.5-line km of veins identified to date (see figures 1 & 2).

SNX’s geological team will initiate a field program to complete geological mapping, soil geochemistry surveys and rock chip sampling on mapped vein target areas, to further refine drill targets in preparation for drilling. A program of seven reverse circulation (RC) holes is planned for 1500m in the third quarter of 2024 to follow up the result of 1,270 g/t Ag hit in BHD006 drilled in 2017.

Pinnacle Silver and Gold
Investor Insight
Pinnacle Silver and Gold presents a compelling investment opportunity in the precious metals sector as it continues to advance its flagship high-grade El Potrero project in Mexico and its Red Lake, Ontario assets. The company’s proven business model focuses on rapidly reactivating past-producing mines to generate early cash flow, while simultaneously exploring for district-scale potential, offering a strong value proposition in a bullish gold-silver environment.
Overview
Pinnacle Silver and Gold (TSXV:PINN,OTC:PSGCF,Frankfurt:P9J) is a promising player positioned for growth in the precious metals exploration sector, with its strategic focus on high-potential projects, commitment to responsible mining practices, and experienced leadership team.
Focused on silver and gold projects in the Americas, Pinnacle is strategically placed to capitalize on the growing demand for these valuable resources. Its core projects include the high-grade El Potrero gold-silver project in Mexico, and the Argosy gold mine and North Birch gold project in Ontario’s Red Lake District – each offering near-term development potential and strong exploration upside.
Pinnacle’s current flagship project, El Potrero, is located within the Sierra Madre Gold Silver Trend.
The company's investment appeal stems from several key factors:
- A robust pipeline of projects at various stages of exploration and development
- Strategic focus on high-potential areas in North and South America
- Effective capital management practices
- Aggressive expansion strategy through strategic acquisitions
The company’s business strategy involves the acquisition of past-producing mines that can be put back into production quickly to generate cash flow. By focusing on high-grade, underground mines, Pinnacle can leverage low capex, a smaller operational footprint, easier and faster permitting process and protection against metal price volatility. At the same time, the company conducts brownfield exploration for resource expansion, increasing its potential for district-scale discovery.
Pinnacle's emphasis on creating shareholder value is evident in its approach to project selection and development. The company's portfolio is carefully curated to balance near-term production potential with long-term growth prospects, offering investors exposure to both immediate returns and future upside.
Company Highlights
- Pinnacle Silver and Gold is a Canada-based exploration and development company dedicated to building long-term shareholder value with its silver- and gold-focused assets in North and South America.
- The company’s flagship El Potrero gold-silver project, located in Mexico’s Sierra Madre Belt, has returned exceptional underground sample grades up to 85.1 grams per ton (g/t) gold and 520 g/t silver, with exploration potential across a 1.6 km strike length.
- The 100-percent-owned Argosy gold mine and North Birch project are located in the Red Lake District in Northwestern Ontario, a region famous for gold production and high-grade underground mines.
- The company’s strategy is to generate near-term production from past-producing assets while growing its resource base through modern, brownfields exploration.
- Pinnacle is led by a highly experienced management team with a successful track record in advancing exploration-stage assets through to production.
Key Projects
El Potrero Gold-Silver Project
El Potrero is a high-grade, past-producing gold-silver project located in the prolific Sierra Madre Belt in Mexico, within 35 km of four operating mines, including Fresnillo’s 4,000 tpd Ciénega Mine. The project comprises two concession blocks totaling 1,074 hectares, which include the historic mines and a 100 tpd on-site processing plant.
Recent Developments (as of July 2025):
- Over 600 rock samples have been collected from underground and surface sources for geochemical analysis.
- Channel sampling at the Pinos Cuates mine returned assays of up to 85.1 g/t gold and 520 g/t silver over 0.5 m, and composite intervals of 50.3 g/t gold and 269 g/t silver over 1.7 m.
- Geological interpretation highlights a significant quartz-feldspar porphyry dyke as a structural control on gold-silver mineralization.
- The Dos de Mayo vein system has been mapped over 1.6 km with trench and underground samples showing high-grade mineralization, including 13.2 g/t gold and 2,280 g/t silver from surface grab samples.
- Work is underway to design an underground and surface drill program to define continuity and guide future mine development.
- A site inspection of the 100 tpd plant confirmed that the base infrastructure is sound. Refurbishment of key equipment (crusher, mill, Merrill Crowe circuit) is being planned.
- Permitting efforts are progressing efficiently, aided by the site's historical disturbance. Baseline studies and formal permitting proposals are underway.
Pinnacle can earn an initial 50 percent interest upon production and increase its ownership of El Potrero to 100 percent subject to a 2 percent NSR, primarily through cash flow-funded payments, offering a low-dilution path to full ownership.
Argosy Gold Mine
Located within the Birch-Uchi Greenstone Belt in Ontario’s Red Lake District, and approximately 10 km from First Mining’s Springpole deposit, the Argosy gold mine produced 101,875 ounces at 12.7 g/t gold from 1931 to 1952. Pinnacle owns 100 percent of the project, subject to a 2.5 percent NSR.
Exploration Highlights:
- Past drilling intersected high-grade mineralization, including:
- 14.67 g/t gold over 1.7 m (No. 3 Vein)
- 12.02 g/t gold over 1.29 m (No. 8 Vein)
- 11.75 g/t gold over 1.55 m (No. 2 Vein)
- The project offers strong depth potential, with 2002–2004 drilling intersecting multiple new veins and gold mineralization extending to 400 m vertical depth.
North Birch Gold Project
Located 4 km from the Argosy Mine, North Birch is a 3,850-hectare grassroots project with major upside. The property lies in an underexplored section of the Birch-Uchi Belt and covers a folded and sheared iron formation, interpreted as analogous to Newmont’s Musselwhite Mine.
Exploration Work:
- LiDAR surveys and IP geophysics have revealed 8+ km of structural breaks with multiple drill targets.
- 2022 drilling intersected anomalous gold and copper mineralization within structurally deformed and altered iron formations, confirming the favorable structural setting
