Bellavista Resources (ASX:BVR) reports that the first phase of drilling at its Brumby Zinc-Silver-Copper Project, located 130km south-west of Newman is now completed.
The company further advises that all 7 diamond holes intersected the Brumby zinc-silver-copper target zone, extending the mineralised footprint to over 7km on an east-west strike length.
Bellavista Resources reports the mineralised system remains open in all directions on both the RC and diamond lines.
An Indigenous Heritage survey, clearing the entire area for the phase two drill program is expected to start shortly. The survey will cover the entire NW portion of the Brumby Target, allowing future programs to continue in this area without the need for further surveys.
An RC rig with big air capability is being secured from our RC drilling partner, Strike Drilling, for the phase two program. Subject to clearing of tracks and pads, phase two drilling is expected to begin in early in 4Q 2022.
Addressing the drilling results, Bellavista Executive Director Mick Wilson said: “Visual inspections of both core and RC chips reveal we have intersected the target horizon along two parallel traverses around 2.5km apart.
This demonstrates an extensive mineralised footprint. We are also encouraged by the presence of regional structures and secondary sulphide*, providing scope for higher grade zones.
“we now have a ‘library’ of diamond drill core across 7km of strike of the Brumby system”
Importantly, we now have a ‘library’ of diamond drill core across 7km of strike of the Brumby system. We can compare grade distribution and the other geological characteristics in the process of vectoring toward feeder zones and areas where metal-bearing fluid has migrated up deep tapping structures.
Once our initial pXRF data is assessed, we will seek to close in on higher-grade areas with a combination of geochemical vectors, geology and geophysics, such as the passive seismic survey currently deployed over 8km-square of the Brumby System. A follow-up drilling program is also being planned, with heritage surveys commencing shortly”.
The drilling program is aimed at expanding the known mineralisation footprint at Brumby, which is already estimated to cover 30km-square (based on historical drilling), and specifically target areas where ‘high-grade’ mineralisation may exist.
Numerous holes from the historic work did not reach target depth, and no diamond core was available prior to Bellavista’s maiden program.
From initial observations, all diamond holes appear to have intersected the Brumby zinc silver-copper target horizon, extending the mineralised footprint significantly.
Scout RC holes (BRRC0001-0003) drilled on a 3km east-west strike length, approximately 2.5km north of the nearest Brumby historic hole. The middle hole BRRC0002 intersected a ‘significant’ number of visible sulphides from approximately 190m (trace to semi-massive –pyrite and several other fine-grained sulphide species) in the target black shale horizon to the end of the hole (250m).
A fourth RC hole (BRRC0004) has intersected multiple black shale horizons in the fold nose. If mineralised, this takes the scale another 1.5km further West.
All RC samples have been dispatched to the laboratory in Perth, with assays expected in 6-8 weeks. All core is being prepared and dispatched for initial continuous XRF before selected zones from each hole will be cut, sampled, and sent for assay.
