Brent Cook

Doug Already Bought It - Noble Plains Uranium (TSXV: NOBL | OTC: NBLXF)

• Top takeaway Cook's probing exposes the technical gaps: no leach kinetics yet, and the three Fort Union test holes found clean but unoxidized sands — meaning the real roll front has not been found at depth.
• His verdict is 'the price is right, but I'm gonna watch it': confirmation drilling mostly re-proves known ground, another raise looms against roughly 30M warrants, and depth at Duck Creek would have to be found first.

Noble Plains Uranium (TSXV: NOBL) buys historic Wyoming uranium ground and converts legacy drill data into compliant resources, skipping grassroots exploration risk. Flagship Duck Creek holds a maiden 6.36-million-pound uranium resource (83% indicated) beside Cameco's and Uranium Energy's Powder River Basin projects. In-situ recovery (ISR — leaching uranium with solution underground rather than mining it) underpins the plan; management wants 20-25 million pounds before a production decision. Ur Energy took a 6.2% stake and signed a processing LOI, so Shirley Central pounds could pipe into its brand-new adjacent ISR plant. The panel flags a 30-million warrant overhang, serial commodity pivots, and thin cash, yet most agree the nano-cap valuation already prices much of the risk.

I Asked The Greatest Junior Mining Investors What They Are Buying Right Now | Rule Symposium

• Top takeaway Cook says quality projects run by quality people are getting to reasonable prices again, and that the job is to do the due diligence on the exhibitors: find a high-margin deposit or a discovery with that potential, big enough that the company does not have to build it, because someone is going to buy it.
• He says the opportunity is across the board rather than one category, covering developers drilling out a resource and grassroots exploration in a good area, but it always comes down to quality.
• He owns a junior royalty company in the western US and uses it as the worked example of the prospect generator model: geologists find a property, do not take it far, bring in a partner, usually a junior, and retain a royalty that eventually comes through.
• He notes you cannot easily outcompete a larger quality company, which is the point of attaching a royalty to that model.

Gold and silver fell 30-50% from highs, and multiple guests frame the pullback as a buying window for quality developers, not a trend break. AISC (All-In Sustaining Cost — what it really costs to produce an ounce) explains the margin math: $4,000 gold against a $2,000 AISC. One guest argues gold pays no dividend, so valuation must run against debt, money supply and GDP instead of cash flow. Royalty companies and prospect generators are presented as the safer way to play gold and silver than owning operators outright. Several guests expect a wave of mining M&A, because producers shed high-cost operations and hold cash without a growth pipeline.

The Only Mine Standing: Antimony Resources [CSE: ATMY | OTC: ATMYF]

Antimony Resources' Bald Hill project targets 2.7 million tonnes at 3–4% Sb (antimony), with a maiden resource expected in Q4 2026. China controls over 70% of global antimony supply and cut off US exports in 2024, creating urgency for Western sources of this critical mineral. CEO Jim Atkinson previously led geology at the Lake George mine, once North America's only antimony producer, bringing relevant experience to Bald Hill.

A $95 Million Company Sitting On a $340 Million Mine

• Top takeaway Delivers a skeptical verdict: the production timeline strikes him as aggressive and the $83M capex as too low, and he doubts a leach pad can be built in the Sonoran Desert for the stated cost.
• Argues the exploration upside is unproven, describing the drilled structures as small, narrow, scattered veins, and expects most time and money on a small mine to go into fixing problems rather than growth.
• In Q&A he pressed on pit count and whether the pits coalesce at depth, the deeper drilling, the cut-off grade cut from 0.2 to 0.17 g/t, and who actually bought the ~$27M raise.

Sonoro Gold's PEA (Preliminary Economic Assessment) for Cerro Caliche shows a $360 million after-tax NPV at $3,500 gold, versus a $95 million market value. Management argues the Mexico discount reflects permitting paralysis under the prior administration, with approvals now accelerating under new leadership and stricter standards. A 50,000-meter, two-rig drill program targets higher-grade zones at Batamote, Diana and newly acquired Acuna Landia, aiming to lift grades and resources. PEA economics rest on 72% heap-leach recovery, $83 million initial capex and $1,900 AISC (All-In Sustaining Cost — the full cost per ounce), which panelists questioned. Panel debate weighed warrant overhang, thin institutional ownership and Mexico risk against management's track record, production-first plan and recent $51 million raise.

Nevada's Greatest Silver Bonanza, Finally Consolidated — and Ready to Drill With Modern Equipment

• Top takeaway Brent Cook opens the questioning by admitting he would love to pick the story apart but cannot find the flaw, and presses on whether open-pit mining is even permitted in the Comstock historic preservation area.
• He says he was glad to hear calcite and adularia in the veins at the Occidental — good evidence the ground sits high in the system — and calls it unfathomable that no hole deeper than 300 feet has been drilled along a vein with the same orientation as the main Comstock Lode.

MacKay Gold & Silver has consolidated most of Nevada's historic Comstock district, giving it a fully funded 20,000-metre drill program starting on the parallel Occidental-Brunswick structure. Higher calcite and a lower gold-to-silver ratio suggest the Occidental sits near the top of the epithermal system (one formed by hot mineral-rich fluids near surface), leaving untested bonanza-grade potential at depth. Shallow oxide drilling has already returned 25 metres at 13.5 grams per tonne gold; management targets outlining one to two million ounces within a year, with first assays around late summer. A USD$60 million financing at $1.40 delivered roughly two to three years of exploration runway, largely royalty-free ground, and a veteran expert panel that could not identify a fatal flaw.
