Pinnacle Silver & Gold has three gold and silver assets in Mexico (1) and Ontario (2) and is led by veteran geologist Bob Archer. This report provides a detailed examination of the company’s strategic shift toward near-term production at the El Petoro project in Durango, while its Canadian assets remain on hold due to funding constraints. Drawing from a comprehensive interview with Archer, the report dives into the company’s corporate history, asset ownership structure, financial position, capital strategy, management track record, and near-term plans, offering readers a clear-eyed look at whether this early-stage story has the technical and financial foundation to execute its cash-flow-first model.
TL;DR
- 1. Pinnacle Silver & Gold is focused on restarting the small-scale, past-producing El Petoro mine in Mexico within 2–3 years, aiming to self-fund future exploration.
- 2. El Petoro was briefly in production in the late 1980s but has sat idle for 35 years, although its current condition, resource potential, and restart costs are unverified.
- 3. CEO Bob Archer owns just under 8% of the company, has not drawn a salary in three years, and emphasizes minimizing dilution, though future financing is still equity-dependent.
- 4. Pinnacle’s Canadian assets—including the high-grade Argosy Mine and North Birch exploration target—are inactive due to lack of funding, with no work planned in 2025.
- 5. Success hinges on early underground sampling results at El Petoro, securing drill permits, and raising capital to begin drilling, which are targeted for completion in 2025.
Who is Bob Archer, and what qualifies him to lead Pinnacle Silver & Gold?
Bob Archer is a geologist with over 45 years in the mining industry, having worked for majors such as Newmont, Placer Dome, Noranda, and Rio Algom before transitioning into the junior sector in 1996. He was a co-founder and long-time CEO of Great Panther Silver, a company he led from concept to mid-tier producer status between 2004 and 2017. Under his leadership, Great Panther acquired and rehabilitated the Topia mine in Durango, Mexico, and later the Guanajuato mine, growing to a peak market cap of ~$600 million during the 2011 silver bull market.
Archer stepped down from Great Panther in 2017, leaving what he described as “$100 million in the bank and no debt.” The company subsequently acquired a mine in Brazil, a decision made by his successor, which ultimately led to bankruptcy. Archer emphasized that he was no longer involved with the company by the time it entered creditor protection.
He joined the board of Newrange Gold (now Pinnacle) in 2018 and became CEO in 2019. Archer claims he received no founder’s shares and has paid for all of his current holdings in the company, which amount to just under 8% of shares outstanding. He also confirmed that neither he nor his board hold any royalties on Pinnacle’s projects.
Why did the company change its name and direction?
Archer took over the company, then called Newrange Gold, after its Nevada project began to underperform and a shift in strategy was deemed necessary. The company changed its name to Pinnacle Silver & Gold in 2023 following the termination of a proposed reverse takeover (RTO) deal with Australian firm Mithril Resources.
The RTO was centered around a Durango project that Archer considered highly prospective. However, the deal failed to close after eight months of legal delays, primarily on the Australian side. According to Archer, both companies were financially strained and unable to proceed. Mithril retained the asset and drilled it post-termination, producing strong results and an ~8x stock price increase—something Archer points to as evidence of his project-selection acumen.
Following the failed RTO, Pinnacle pivoted again—this time to the El Petoro project in Durango, Mexico. Archer described this as “coming full circle,” referring to his earlier experience at Topia, located 13 kilometers away.
Who owns Pinnacle Silver & Gold?
At the time of the interview, the company had 81.5 million shares outstanding and approximately 110 million fully diluted. Insider ownership is ~25%, with Archer holding just under 8%. A new insider, Michael Kott of Munich, Germany, recently acquired a significant block, now owning roughly 11%.
According to Archer, approximately 35% of the stock is closely held. There are no major institutional investors; the shareholder base is predominantly retail. Archer states that he has invested in around 40 mining companies, primarily juniors, and holds his Pinnacle position personally rather than through a corporate entity.
What is the company’s asset portfolio and why does it have three projects?
Pinnacle currently holds three projects:
- – El Petoro, a past-producing underground gold-silver mine in Durango, Mexico.
- – Argosy Historic Mine, a high-grade past-producing gold mine in the Birch-Uchi greenstone belt of Ontario.
- – North Birch, an early-stage gold exploration project adjacent to Argosy, targeting iron formation-hosted gold.
All three were acquired opportunistically. According to Archer, his goal was to avoid being a “single-asset company,” a strategy shaped by his past experiences and current market conditions. However, he acknowledges that only El Petoro is currently being advanced. The Ontario assets are on care and maintenance due to capital constraints.
What is the business strategy?
Archer stated the company’s core strategy is to “get into production quickly” at El Petoro and use cash flow to eventually fund exploration at the Canadian projects. This mirrors his approach at Great Panther in the early 2000s.
The Petoro project is seen as a low-capex, fast-track opportunity. The mine has been privately held for ~40 years and contains an on-site mill rated at ~100 tpd, built by the vendor in the late 1980s. It was in production briefly but has sat idle since. Archer described the vendor as a mining contractor with another operating mine nearby and a desire to see this asset put back into production.
According to Archer, this alignment of interests allowed Pinnacle to negotiate a 50/50 profit-sharing arrangement with the vendor, with an option to earn up to 90% ownership via staged payments totaling $4 million (plus shares). The company currently holds no equity in the project but is funding early-stage rehabilitation and sampling.
Archer emphasized that the project is on private land (not ejido), the vendor owns the surface rights, and there are no royalties. He also claims there is strong community support, given prior mining activity in the area.
What work is underway in Mexico?
As of the interview, underground rehabilitation had started using local contractors. Surface and underground mapping and sampling had also begun, with the first batch of samples submitted to the lab. Archer stated the company would evaluate whether to release results in batches or wait until they had a cohesive data set.
Upcoming plans include:
- – A LiDAR survey to support structural interpretation
- – Surface clearing of the plant site
- – Equipment assessment
- – Drill permit applications
- – Baseline environmental work
Archer expects drilling to begin in approximately six months, contingent on financing.
How much money will be required, and how long will it take to reach production?
According to Archer, the estimated cost to rehabilitate and restart El Petoro is US$2–3 million, with a projected timeline of 2–3 years. This estimate includes basic mill refurbishment, underground development, and drilling. However, he acknowledged that this is a forward-looking assumption without sufficient cost data at present.
Asked about production potential, Archer pointed to a hypothetical case: 100 tpd throughput at 10 g/t AuEq could produce 11–12,000 ounces annually. If realized at a US$1,000/oz margin, this would generate ~$11–12 million in annual profit.
No resource estimate or economic study has been completed. Archer stated that developing a small, low-cost mine is feasible in Mexico but “would not be possible in Ontario” due to permitting timelines.
How will Pinnacle finance the project?
Archer confirmed the company had recently raised $800,000 via equity, the maximum allowed under TSX Venture rules due to the share price being below $0.05. Most of the funds came from European investors and two strategic Mexican mining investors.
The company will need additional funding for drilling. Archer said he would prefer to finance through equity and avoid early asset-level deals or royalties. However, he is open to alternative financing methods (e.g., gold loans, off-take agreements, or streaming) once the project is de-risked.
For now, there are no immediate plans to joint venture or sell interests in the Canadian projects, which Archer called “pet projects” and long-term plays.
What’s happening with the Ontario projects?
Little to no work is planned for 2025. Archer confirmed that lack of funds is the primary reason. Argosy is fully permitted and owned 100%. North Birch is held 100% with no holding costs and sufficient assessment work completed to retain it for several more years.
Archer stated the company’s plan is not to bring Argosy into production itself but to delineate a resource and potentially monetize the asset. Both assets are located 10–12 km from First Mining’s 5Moz Springpole project.
Why not sell or option the Canadian assets?
Archer indicated he is not ready to part with the Ontario projects, particularly North Birch, which targets an iron formation model he developed during his time at Placer Dome’s Musselwhite mine. He also noted a lack of potential partners currently active in the region.
“Not many companies are working up there,” he said. “Even if you want to option them, who are you going to option them to?”
What are drill costs in Mexico?
Archer estimated drill costs at around US$150 per metre, including assays, though acknowledged no contractors had been formally engaged. He plans to attend an upcoming conference in Mexico to meet with drill providers and obtain firmer pricing and availability estimates.
What is the G&A outlook for 2025?
Archer confirmed that G&A would remain lean. He and the CFO have not taken salaries for the past three years, with accrued amounts appearing as long-term payables on the balance sheet. There is no corporate office; the company uses the CFO’s accounting firm as its mailing address.
A part-time IR consultant was recently added. Archer stated that all new technical personnel would be brought in on a contract basis and only to support work in Mexico.
What is the marketing strategy?
Pinnacle spent approximately $21,000 per month on marketing in the six months ending October 31, 2023. Archer said those numbers were inflated by a few large one-off contracts tied to the failed RTO and won’t be repeated.
The 2025 marketing budget is expected to be around $100,000, focusing on:
- Select investor conferences (including matchmaking-style one-on-one formats)
- Increased social media presence
- Direct outreach in Europe and Mexico
Archer noted the need to adapt to a changing investor demographic, acknowledging that younger investors behave differently than traditional resource investors and may require different engagement strategies.
Are there security concerns at the Durango border?
The project lies near the Durango-Sinaloa border, a known region of cartel activity. Archer acknowledged the location but stated that in his 20 years working in the region—including at Topia—there have been no incidents. “We mind our business, and they mind theirs,” he said.
What does success look like in six months?
According to Archer, success by late 2025 would mean:
- Underground sampling confirms continuity and high grades
- Drill permits approved
- Drills turning at El Petoro
- A clearer assessment of plant refurbishment needs
- Progress on baseline environmental studies
“If we can be drilling in six months and generate solid targets based on the underground work, I’ll be happy,” he said.
