BRS Resources Starts Backpack Drilling at SilverGold Mountain

BRS Resources has started drilling at SilverGold Mountain, its gold-silver-copper project in Mexico’s Mulatos district. The company announced on 7 October 2026 that a backpack-portable diamond rig is now at work, with a target of at least 30 holes this month.

The entire kit weighs about 20 kg and is carried in by hand. The ground it is testing sits beside two of the district’s best-known operations: Alamos Gold’s Mulatos mine and Agnico Eagle’s La India mine.

Each hole is aimed directly beneath the surface rock samples BRS reported in August, which peaked at 2.06 g/t gold, 76.3 g/t silver and 1.20% copper. This is the first test of whether those grades hold below the surface.

What is the 30-hole October programme designed to prove?

The drilling asks one question: do the surface grades continue downward?

August’s results came from 16 samples certified by Skyline Assayers & Laboratories in Tucson, Arizona. Grades ran consistently above 0.95 g/t gold and 50 g/t silver, which points to a connected multi-metal system rather than a single isolated hit. Surface rock, however, can be enriched or misleading. Core drilled from directly underneath is the check.

The programme is built around that check:

• At least 30 holes in October, at a pace of at least three holes per day
• 37 mm diameter core from depths of up to 20 m
• A portable rig supplied by Shaw
• Drill sites chosen using drone-mounted lidar (laser terrain mapping) and surface sampling

This is a continuity test, not a resource-definition campaign. The rig recovers solid, continuous core, and a two-person crew can move it on foot, by ATV, by boat or by helicopter. Holes can therefore follow the mineralisation across rugged ground without roads or large cleared drill pads.

Drone-mounted lidar, surface geochemistry and portable drilling now sit alongside traditional mineral exploration methods, letting juniors test targets faster and at lower cost than conventional campaigns.

CEO view on the rig Chief Executive Officer Byron Coulthard described the rig as a major upgrade on surface trenching, calling it more effective and more efficient.

BRS expects the core to feed a compliant technical report, and the release was approved by Qualified Person Allan L. Schappert. For you, this means the surface story could be confirmed or weakened within weeks. The October assays are the project’s first real test.

How does SilverGold Mountain sit next to Mulatos and La India, and what does BRS actually control?

The neighbourhood is a strong selling point. BRS’s four concessions cover 947.7 ha and adjoin Mulatos, which BRS cites at 3.4 Moz, and La India, cited at 1 Moz. Those are district-scale endowment figures, not current reserves or production. Alamos puts Mulatos district reserves at about 1.2 Moz at roughly 4.00 g/t gold. Recent detailed production data for La India was not available.

Historic veins on the ground add weight. Veta 8, Veta 5, Veta 1, Los Pericos and El Aguilillo have returned historic grades of 2-19 g/t gold, including up to 19.5 g/t reported by Minas de Oro Nacional, an Alamos subsidiary.

Proximity supports the geological case. It does not guarantee ore.

What the LOI does and does not secure

BRS does not yet own an interest in the project. It signed a letter of intent (LOI), a preliminary agreement on terms, on 20 June 2026. The LOI is non-binding.

• Up to 75% interest through an earn-in, meaning BRS gains ownership by funding exploration
• Subject to due diligence, a definitive agreement, and regulatory and exchange approvals
• Right of first refusal on any sale of the vendor’s retained interest

An NSR royalty is a cut of revenue from metal sales, paid to the vendor after smelting costs. Read these terms as an option on the project, not ownership of it.

Earn-in agreements are a common route for juniors to secure ground without paying full price upfront, and the structure ties ownership to exploration spending milestones rather than cash at signing.

What are the limits of a 20-metre backpack drill, and what comes next?

The rig’s strengths are also its ceiling. A 20 m depth limit and narrow core can show whether mineralisation continues near surface. They cannot reach deeper ore shoots or support a resource estimate.

Key point Backpack drilling is a screening tool, not a resource tool.

No NI 43-101 technical report, the Canadian standard disclosure for mineral projects, has been filed. As of 8 October 2026, no October drill results have been released.

• Epithermal grades, typical of this belt, can change sharply with depth
• Small core may capture a localised high-grade vein rather than a broad zone
• The LOI could fail to close
• Funding the US$5M commitment may require share issues, diluting existing holders

Even with gold at record levels, juniors still face stop-start financing windows, which is why the cost of funding a US$5M earn-in commitment can matter as much as the drill results.

Junior explorers commonly follow early portable drilling with conventional diamond campaigns, and BRS appears to be on that path. The sequence to watch:

1. October assay results
2. Signing of a definitive agreement
3. Deeper conventional diamond drilling
4. A filed technical report

Strong shallow results should prompt you to expect deeper drilling and fresh financing, not to assume an economic deposit.

What the October holes can settle, and what they cannot

This programme answers one narrow question: whether the gold, silver and copper found at surface persist in the first 20 m. Good assays would justify the next step. They would not prove a mine or secure the deal.

Your checkpoints are the assay release, a signed definitive agreement and any move to deeper rigs. How BRS funds that next phase may shape shareholder outcomes as much as the core itself.

How BRS funds the next phase comes down to capital quality, since cheap money raised on early shallow results can leave existing holders heavily diluted before deeper drilling begins.
