49 Metals has secured a historical database pointing to broad, near-surface gold mineralisation and extensive gallium anomalism at its Buffalo Canyon project in Nevada. The data came at no cash cost, but the opportunity remains unverified and still requires new exploration.
- 63 historical holes totalling approximately 11,280 metres
- Gold intercepts including 182.9 metres at 0.39g/t from surface
- Gallium anomalism extending up to 379.5 metres downhole
- Database licensed for no cash consideration and a perpetual 1% NSR royalty
- Gold Mountain drilling remains 49 Metals’ immediate priority
Historical drilling reveals a broad Buffalo Canyon gold system
49 Metals Limited (ASX:49M) has added a potentially sizeable second act to its Nevada portfolio, acquiring access to a historical geological database that records broad gold mineralisation from surface at the 100%-owned Buffalo Canyon project.
The database covers 63 historical holes totalling approximately 11,280 metres. Among the strongest reported intersections are 182.9 metres at 0.39g/t gold from surface, 152.4 metres at 0.42g/t and 161.5 metres at 0.38g/t. The results are downhole lengths, however, and true widths have not yet been established.
Drilling at the Everson prospect was conducted by several previous operators between 1992 and 2017. 49 Metals says the results indicate an extensive, open-ended reduced intrusion-related gold system, with mineralisation remaining open along strike and at depth. The company also points to a 2.0km by 1.6km magnetic high that may reflect a larger concealed intrusive system beneath the known mineralisation.
The reported grades are broadly comparable with the head grades of large Nevada heap-leach operations, according to the announcement. That comparison is useful as a geological benchmark, not proof of economic viability: continuity, tonnage, recovery, strip ratio and processing characteristics have yet to be demonstrated at Buffalo Canyon.
Gallium adds a second, untested layer to the project
The more unusual feature in the dataset is gallium. Four 2017 drillholes on the western side of the gold prospect returned continuous gallium anomalism from surface over 288 to 379.5 metres, with average grades ranging from 16.8g/t to 19.6g/t. All 258 available gallium assays from those holes exceeded 10g/t.
49 Metals says the gallium appears to be associated mainly with lithophile elements rather than the gold mineralisation, suggesting it could represent a separate and spatially extensive geochemical system. The company has not yet established whether the signature reflects hydrothermal enrichment, host-rock composition or a combination of both.
That distinction matters. Gallium’s strategic value is clear, but the announcement contains no mineralogical, metallurgical or economic evidence that Buffalo Canyon’s gallium could be recovered commercially. The planned work will investigate the minerals hosting it, its relationship with alteration and lithology, and whether it might eventually contribute by-product or co-product value.
No-cash database deal leaves validation as the next test
49 Metals has licensed the database from Genex Exploration, a subsidiary of Orogen Royalties, for no cash or shares. In return, Genex receives a perpetual 1% net smelter royalty covering minerals produced from the existing claims and additional mineral interests acquired within a one-mile area of interest.
The company receives a perpetual, irrevocable and transferable licence to use the historical information, while new interpretations, models and exploration targets remain its property. But the dataset carries familiar historical-data limitations: sampling and recovery records are incomplete, quality-control procedures vary between campaigns, survey coverage is uneven and no independent verification drilling has been completed.
For now, Buffalo Canyon is therefore an exploration option rather than a defined development asset. 49 Metals plans to validate the database, refine its geological model, generate targets and undertake mineralogical and preliminary metallurgical work. The company’s immediate operational focus remains Gold Mountain follow-up drilling, where the second campaign is nearing completion and assays are pending.
Bottom Line?
Buffalo Canyon offers 49 Metals meaningful exploration upside at limited upfront cost, but the next value test is verification rather than another headline intercept.
Questions in the middle?
- Can 49 Metals independently validate the historical gold grades, sampling quality and drillhole geometry?
- Will new drilling confirm that the broad downhole intercepts translate into meaningful true widths and continuity?
- Does the gallium occur in minerals and concentrations that can be economically recovered alongside any future gold operation?
