Larvotto Resources Limited (ASX: LRV) has kicked-off Reverse Circulation (RC) drilling at its Mt Isa Project in Queensland.
Initial drilling will target the Yamamilla and Whitehorse Prospects, two highly prospective areas identified from Larvotto’s regional geochemistry and field mapping.
The Yamamilla Prospect is one of our lead areas, with over 10km of mineralised strike that contains a well-defined geochemical and geophysical anomaly,” Managing Director, Ron Heeks, said.
“The majority of holes from the very limited historic drilling back in 2012 were mineralised, but significantly, most did not reach the planned target due to drilling issues at the time. Whitehorse has been identified from Larvotto’s recent field work and has produced extremely high-grade rock chips over 2,300m of strike. We look forward to commencing the initial drilling of very promising targets and reporting our results to the market in due course.”
The Yamamilla Prospect, which includes the YM8, Yamamilla South and Portal Creek prospects, lies along the regional scale northwest-trending Prospector Fault Zone. This Zone extends for over 10km and is host to high-grade copper-gold mineralisation at the Prospector/Leichhardt Copper deposit, located directly to the north that contains a historic resource of 894,000t @ 1.03% Cu including a best intersection of 71.5m @ 1.72% Cu, 0.18 g/t Au.
Mineralisation at Yamamilla is characterised by linear zones of gossanous quartz veining and brecciation, which have developed along the Prospector Fault. The presence of untested VTEM conductors and geochemical anomalies also reinforces the area’s prospectivity for iron-sulphide-copper-gold (ISCG)-style mineralisation. Testing of these key zones will be the focus of this phase of drilling.
Approximately 2,500m of targeted drilling will test the geochemical and geophysical anomalies at Yamamilla. Drilling will be undertaken by a track mounted, high-capacity air RC drill rig. Geophysical VTEM anomalies and geochemical anomalies along the Yamamilla Fault were poorly drill tested by historic RC drilling in 2012, when most of holes failed to intersect the targeted zones, predominantly due to a lack of air whilst drilling.
To alleviate this reoccurring, Larvotto is utilising a drill rig that has the ability to withstand these issues.
However, it is important to note that even with these issues in the historic drilling, the majority of holes still produced significant hits from mineralisation adjacent to the target zone, suggesting the possibility of multiple mineralised horizons.
