Bronco Resources (TSX-V:BRON) has identified a previously unrecognised style of ‘high-grade’ gold mineralisation at its Placer Mountain Gold Project in British Columbia, Canada.
Sampling returned 51.6 grams per tonne gold (Au) and 228g/t silver (Ag) about 280m east of the Kodiak Zone discovery outcrop.
The sample comprised angular blue quartz containing minor sulphides and sits within the eastward projection of the Kodiak mineralised system, coincident with a deep magnetic low. The company has flagged the target as ‘high priority’ for drilling.
A second float sample 350m east of Kodiak returned 2.9g/t Au and 15.7g/t Ag. An outcrop grab sample 65m north of Kodiak returned 55g/t Au and 149g/t Ag, with 10% iron.
Bronco says the blue quartz is a newly recognised style at Placer Mountain, near Princeton. Earlier samples grading above 20g/t Au generally carry elevated iron and abundant sulphides, whereas the blue quartz vein contains very low iron.
Grab samples are selective and do not necessarily represent mineralisation across the property.
Chief Executive Officer Dev Rishy-Maharaj says the vein is “a different beast”.
“That gives us an important piece of info as we continue to understand the different phases of gold mineralisation, especially how they may be expressed in newly completed geophysical imagery,” Rishy-Maharaj notes
“This detailed set of imagery will guide the next phase of drilling at the project.”
MSALABS completed the analysis using photon assay and fire assay methods. Bronco continues to evaluate how the blue quartz relates to the magnetic and non-magnetic phases at Kodiak.
Bronco holds 88% of the project in a joint venture with Universal Copper (TSX-V:UNV). Separately, director Ron Parratt resigned effective 12 October, after serving on the board since January 2022.
