Majuba Hill's Copper Depth Charge: Why Giant Mining Could Be the Next Big Energy Transition Play

The global energy transition is on a collision course with a stark reality: copper supply is not keeping pace with demand. As electric vehicles (EVs), solar panels, and wind turbines gobble up the "red metal," investors are scrambling for projects that can deliver scale, infrastructure, and—critically—imminent catalysts. Enter Giant Mining Corp.’s (CSE: BFG) Majuba Hill Porphyry Copper-Silver-Gold Deposit in Nevada, where recent drill results at record depths and AI-driven exploration are setting the stage for a transformative Mineral Resource Estimate (MRE) due in Q4 2025.

A Deep-Rooted Discovery with Global Implications

Last month, Giant Mining reported that its MHB-34 drill hole reached a depth of 1,963 feet (598 meters)—shattering its own depth record—and intersected visible native copper extending far beyond 1,600 feet. This discovery, described by CEO David Greenway as “truly extraordinary,” sent shares surging 51% to $0.31 on May 7. But the significance goes beyond a single drill result: it’s a validation of Majuba Hill’s potential to unlock a world-class copper deposit at a time when the U.S. is desperate to secure domestic supply chains.

AI-Driven Targeting: Precision in a Copper-Starved Market

Majuba Hill’s recent progress isn’t just about brute force drilling. The project is leveraging ExploreTech’s Engine AI system, which processed thousands of geophysical models to pinpoint resistivity anomalies—halving the guesswork in targeting copper-rich zones. This AI workflow, which uses cloud-based simulations to refine drill trajectories in real time, has already optimized hole placements like MHB-34, which targeted a high-potential anomaly in the deposit’s southern sector.

The results? A 59% increase in cumulative drilling to over 88,000 feet year-to-date, with core samples sent to ALS Labs for assay. While pending results remain a wildcard, the visual copper observed in MHB-34’s core suggests proximity to primary sulfide zones, a hallmark of high-grade porphyry deposits.

Q4 2025: The Catalyst to Watch

The market’s patience will be tested until Giant Mining delivers its NI 43-101-compliant MRE by year-end. Here’s what investors need to know:
- Depth Cutoff: The MRE will include mineralization down to 1,200 meters (3,937 feet)—far deeper than most porphyry projects.
- High-Grade Definition: “High-grade” is set at ≥2% copper, a threshold met in historical holes like MHB-31, which returned 2.6% Cu over 74 feet.
- Economic Assumptions: A $3.50/lb copper price and 20% waste dilution anchor the model, but rising copper prices (currently ~$3.70/lb) could supercharge economics.

The real game-changer? If assays from MHB-34 and other deep holes confirm continuous high-grade zones, the deposit could leap into the 50–100 million tonne category outlined by a 2023 RESPEC Engineering report. At 2% Cu, that’s 1–2 billion pounds of copper—a game-over result for a sector starved of new discoveries.

Why Nevada? Why Now?

Majuba Hill isn’t just a geological marvel—it’s strategically positioned to capitalize on U.S. critical mineral policies. Nevada, ranked #1 globally for mining jurisdiction by the Fraser Institute, offers world-class infrastructure: paved roads, reliable power, and proximity to rail lines. This reduces permitting risks and keeps costs low compared to projects in politically volatile regions.

Meanwhile, the Biden administration’s Inflation Reduction Act and CHIPS Act are turbocharging demand for domestic copper, with estimates suggesting 20 million tons will be needed to meet EV and grid build-out goals by 2030. Majuba Hill’s timing couldn’t be better.

Risks? Yes. But the Reward Looks Too Big to Ignore

Critics will point to risks: assay delays, metallurgical hurdles, and the ever-present “drill hole to mine” gap. Yet Giant Mining’s fully funded 2025 drilling program and Blossom Social partnership (which boosts investor education) signal confidence. Even a conservative 50 million tonne MRE at 1% Cu would place Majuba Hill among the largest U.S. copper projects—a rare asset in a sector where 80% of mines face closures by 2030 due to depletion.

The Bottom Line: Buy the Dip Before the MRE

Giant Mining’s stock is still nursing a post-spike pullback, but that’s exactly where contrarian investors should step in. With assays pending and a $3.50/lb copper price floor, the MRE could redefine Majuba Hill’s value—potentially unlocking $1 billion+ in resources.

The energy transition isn’t just about lithium and cobalt anymore. Copper is the backbone—and Majuba Hill is one of the few projects capable of delivering the scale the world needs.

Act now, before the MRE resets expectations.
