Black Mammoth Metals expands Arizona footprint with copper-gold sampling at Big Bear, Zulu, and Northern Star

Black Mammoth Metals Corporation (TSXV: BMM; OTC: LQRCF) has expanded its copper and gold exploration portfolio with full ownership and sampling of three contiguous properties in Arizona—Big Bear, Zulu, and Northern Star—adding momentum to its ongoing acquisition-driven strategy in the western United States. On June 16, 2025, the Vancouver-headquartered exploration company announced the completion of initial surface sampling at the sites, which collectively target oxide copper and gold mineralization in historically explored zones.

The sampling campaign follows the staking of 10 federal mining claims and completes the transfer of assets that had previously been optioned in March 2024. With Big Bear and Northern Star showing historical copper oxide activity and Zulu hosting a high-grade underground gold mine, Black Mammoth Metals is preparing for the next phase of exploration, including geophysical surveys and drill testing.

What sampling results and historical drilling data support Black Mammoth’s confidence in the Arizona projects?

At the Big Bear property in Gila County, Black Mammoth Metals confirmed copper oxide mineralization across a vertical interval of 74 meters, sampled across surface outcrops still accessible from legacy drill roads. The site, located 12 kilometers south of Payson, Arizona, has a documented history of drilling activity from the 1950s through 1970s that reported the presence of malachite, azurite, bornite, and chalcopyrite. The historic logs also indicated trace levels of gold and silver accompanying primary copper sulphide mineralization.

The Zulu property, approximately 8 kilometers east of Big Bear, contains the historical Zulu gold mine, where mineralized veins strike northwest across a 1,200-meter corridor. Sampling at surface confirmed the presence of gold mineralization, with one outcropping structure returning a result of 1.8 grams per tonne of gold (Sample Z03). The vein is hosted within a porphyry dike set in a diorite intrusive complex—favorable geology for structurally controlled gold deposits. Additional structures across Zulu are now being mapped to define further exploration targets.

At Northern Star, located in La Paz County and approximately 43 road kilometers east of Parker, the explorer sampled copper oxide mineralization within a 360-meter strike zone dipping 35 degrees to the east. This zone includes three small historical pits from a 1960s heap leach operation, with visible malachite and trace azurite present in outcrops. The underlying bedrock is composed of Precambrian gneiss intruded by Cretaceous porphyry and overlain by silicified Permian limestone, with multiple east-dipping mineralized faults evident across the site.

What exploration activities are being planned for Big Bear, Northern Star, and Zulu following sampling?

Black Mammoth Metals intends to launch induced polarization (IP) surveys at Big Bear to better define zones of deeper copper sulphide mineralization and guide confirmatory drilling across historically mineralized corridors. The IP survey will also help delineate the potential extent of oxide copper zones for near-term drill targeting.

At Northern Star, the exploration team is planning a fence of shallow drill holes to test the downdip continuity of the oxide copper zone and investigate the potential for primary sulphide mineralization along fault structures. The presence of historical workings and consistent fault geometry enhances the structural predictability of future targets.

Zulu will undergo a more comprehensive geological mapping campaign. With the high-grade sample confirming near-surface mineralization, Black Mammoth Metals is working to identify the full strike length of the gold-bearing vein and determine whether additional subparallel structures exist within the porphyry-intrusive setting. A future drill campaign at Zulu will likely focus on verifying historical mining widths and grades along with new anomalies identified from field work.

How was the acquisition of these Arizona properties structured, and why is it financially significant?

Black Mammoth Metals completed the acquisition of the Arizona properties through a non-dilutive option agreement in March 2024, purchasing 10 federal mining claims for a total of USD 75,000 in cash. There are no royalty obligations, work commitments, finder’s fees, or share compensation attached to the deal.

This acquisition framework is consistent with Black Mammoth’s approach to expanding its asset base without introducing shareholder dilution or contingent liabilities. The low entry cost relative to exploration potential gives the Canadian explorer flexibility to direct capital toward fieldwork and geological analysis instead of upfront financial obligations.

What is the institutional sentiment around Black Mammoth Metals’ strategy and stock performance?

Institutional data currently reflects moderate optimism around Black Mammoth Metals as a high-risk, high-upside junior explorer. As of mid-June 2025, shares of Black Mammoth Metals are trading at approximately CAD 1.90, reflecting an 11% daily gain and a 52% year-on-year increase in value. While there is no analyst coverage from major banks, retail sentiment and junior mining forums continue to track the company’s property acquisition cadence and sampling updates.

Recent platform analysis from Simply Wall St indicates a market capitalization in the CAD 60–68 million range, with no operating revenue and standardized net losses typical of early-stage exploration firms. Technical signals are mixed. TradingView shows short-term indicators leaning bearish, while long-term sentiment from platforms such as Barchart rates the stock as a “strong buy” due to momentum and volume surges tied to project news flow.

Without traditional sell-side coverage, institutional sentiment is inferred indirectly from share performance relative to peer explorers, project-specific visibility, and low dilution risk.

How do these projects fit into Black Mammoth Metals’ broader U.S. exploration strategy?

The addition of the Arizona properties complements a growing portfolio of 100%-owned gold, silver, copper, and rare earths assets across Nevada, Idaho, and California. In the past 18 months, Black Mammoth Metals has acquired assets including the Coal Canyon Gold property in Pershing County, Nevada; the Island Mountain Gold District in Elko County; the Leadore REE-silver project in Lemhi County, Idaho; and the Blanco Creek Gold property in central Idaho, which hosts three historic underground mines across a 3,550-meter shear zone.

This acquisition model—focused on historical mining districts, low-cost entry, and strong logistical access—is designed to minimize capital intensity while maximizing optionality. Each new asset adds to a pipeline of drill-ready or near drill-ready opportunities, enabling the firm to sequence exploration and maximize news flow efficiency.

What should investors expect next from Black Mammoth Metals in Arizona?

Analysts and resource investors are closely watching for near-term catalysts, particularly the results of geophysical surveys at Big Bear and follow-up drill permitting at all three sites. If drill programs validate oxide and sulphide continuity at Big Bear and Northern Star—or confirm high-grade intercepts at Zulu—valuation re-rating is likely.

The company’s consistent acquisition of strategic U.S. mineral assets, backed by historical data and favorable geology, positions Black Mammoth Metals to generate early-stage upside without relying on excessive capital markets intervention. Future updates will likely focus on permitting, drill mobilization, and assay results that may unlock deeper value from these recently consolidated Arizona assets.
