Overview

Project Background

Secured With Zero Share Dilution

The past-producing Columbia and Gold Queen (GQ) Mines are key core "spokes" in SBMI's vertically integrated Hub-and-Spoke strategy. Located in the highly productive Gila County, Arizona district, these contiguous properties provide massive tonnage potential and multi-metal exposure to copper, gold, and silver.

Aggressively Protecting Shareholder Equity

In a move that strongly prioritizes capital efficiency, SBMI secured the 12 BLM mineral claims for a minor cash payment, with zero share dilution, no finder's fees, and zero royalties. This ensures maximum upside is retained exclusively for existing SBMI shareholders.

12 Claims Managed

100% Owned Mill Connection

0% Royalty Burden

The Hub-and-Spoke Advantage

Under typical mining scenarios, developing standalone mill processing infrastructure represents up to 80% of start-up CapEx. SBMI eliminates this roadblock:

Our Central Hub (Globe, AZ Mill)

Our fully permitted, 100%-owned operational mill sits 30 miles down the road. All processing asset risks have been bypassed.

High-Tonnage Mine Spokes

While Buckeye and McMorris mines focus on ultra-high-grade silver veins, Columbia and GQ supply robust high-tonnage feed.

Instant Margin Amplification

No transportation to third-party smelters. Fast truck hauling dramatically lowers overall operating cash costs per ounce.

Investment Thesis

Why the Columbia & GQ Mines Matter

An aggressive pathway to production volume, low CapEx structure, and massive resource expansion without diluting stock value.

Rapid Tonnage Scaling

While our primary properties focus on elite but narrow vein structures, the Columbia and GQ mines offer rapid bulk scalability. They are engineered to feed the mill with up to 250 tons per day of high-grade copper/gold feed.

Historic Mining Pedigree

Previously held by mineral titan Phelps Dodge (now Freeport-McMoRan), these sites were historically worked using conventional methods, extracting elite grades strictly within the upper 500-foot oxidation zones.

Immediate Infrastructure

The property delivers direct ownership and physical access to historic underground drifts, massive surface stockpiles, and irreplaceable historic technical geologic data. This substantially lowers SBMI's developmental CapEx.

175,000 Tons Blocked

Historic documentation maps out substantial high-grade material block reserves, noting approximately 175,000 tons of blocked ore located strictly on the Columbia Mine's principal D Vein system.

Near-Term Stockpiles

Substantial surface mineral stockpiles exist directly adjacent to the portal entries. Our technical crew is actively analyzing and assaying this material for immediate trucking and milling at our central plant.

No Financial Anchors

By avoiding standard joint venture/royalty traps, SBMI preserves 100% of the ore profits. No royalties, no finders fees, and absolutely zero common stock dilution. It is a textbook, cash-efficient transaction.

Development Pipeline

Near-Term Catalysts

How SBMI is fast-tracking development at the Columbia and Gold Queen Mine locations to drive cash flow.

Phase 1 • Active Evaluation

Processing Surface Stockpiles

Our metallurgical team is actively processing samples and evaluating existing stockpiles located on-site to ship immediately to our Globe mill, facilitating rapid metal recovery.

Phase 2 • Direct Revenue

Direct Shipping Ore (DSO)

We are actively identifying the highest-grade ore clusters for direct shipping opportunities, enabling cash flow that bypasses standard milling pathways entirely.

Phase 3 • Mine Rehabilitation

Underground Access & Sampling

Our skilled mining crew is preparing access pathways, executing a complete rehabilitation of the existing 1,300-foot crosscut, and readying bulk extraction across the D Vein.
