Spartan Metals Corp. (TSXV: W | OTCQB: SPRMF | FSE: J03) has assembled two very different tungsten opportunities in the American West: a large, comparatively advanced deposit in New Mexico and a group of past-producing mines in Nevada where exploration continues to expand the known mineralized footprint.
In a recent InvestorNews interview, Tracy Hughes spoke with President, CEO and Director Brett Marsh about why he built Spartan around tungsten and how the company’s portfolio could contribute to America’s critical minerals supply chain.
In New Mexico, Spartan’s Victorio Project contains a 2012 historical mineral resource estimate that the company describes as the largest tungsten resource in the United States. Approximately 100 historical drill holes have already been completed, allowing Spartan to concentrate on updating the resource, completing engineering studies and evaluating a potential development path rather than beginning with grassroots discovery.
The scale of Victorio is complemented by the Eagle Project in eastern Nevada, which includes the past-producing Tungstonia, Yellow Jacket and Rees/Antelope mines. Marsh said historical production initially attracted Spartan to the district because it established that tungsten mineralization was present and potentially recoverable using the methods available at the time.
Recent work has substantially widened that opportunity. Spartan reported that exploration at Tungstonia expanded the defined tungsten-silver mineralization footprint more than thirteenfold to approximately 5.7 square kilometres. Eight veins have now been confirmed over a cumulative exposed surface strike length of approximately 6.8 kilometres, with individual rock samples assaying as high as 5.18% tungsten trioxide. Sampling at the Rees Mine also returned individual assays of 6.76% and 8.48% tungsten trioxide.
Marsh believes the combination of multiple former mines, high-grade surface occurrences and newly identified skarn mineralization could indicate a considerably larger system than earlier operators recognized. Geophysical work is now being used to refine targets ahead of planned drilling.
Tungsten remains the foundation, but it is not the portfolio’s only potential source of value. Spartan has also identified silver, rubidium, antimony and copper at Eagle, while Victorio contains molybdenum, fluorspar and other critical minerals requiring further definition.
For Marsh, the broader opportunity extends beyond traditional metals markets. Tungsten is used in semiconductor manufacturing, advanced industrial equipment and defence applications, placing it directly inside many of the technology supply chains now facing heightened geopolitical pressure.
“If investors are into tech, go back through the value chain and look at all the inputs that go into that technology,” Marsh said.
Spartan’s strategy is clear: advance domestic projects where tungsten is already known to exist and reconnect America’s technology ambitions with the raw materials required to realize them.
