Musgrave Minerals Ltd (ASX: MGV) has received further strong assay results from reverse circulation (RC) drilling at the Big Sky and Target 14 Prospects along the new gold corridor south-west of Lena and Break of Day on its 100% owned ground at its flagship Cue Gold Project in Western Australia’s Murchison district.
Recent assays from RC drillholes continue to define thick regolith gold mineralisation within the extensive 2.6 km-long aircore gold anomaly at Big Sky.
Managing Director, Rob Waugh, said gold mineralisation remains open down dip at Big Sky and infill resource definition RC drilling has commenced.
Target 14 also remains open and further drilling to follow-up the recent intercept will commence in October
Big Sky and Target 14 are new and exciting discovery opportunities for the company,” Mr Waugh said.
“Thick, near-surface, oxide gold mineralisation has been identified over broad intervals at Big Sky, which has the potential to add significant feed tonnes to a future operation focused at Break of Day and Lena.
“The potential addition of soft oxide mineralisation from Big Sky, together with the higher-grade Break of Day and Lena deposits only 2km to the north could significantly improve sustainability of production scheduling and help provide feed continuity over a longer potential operating term.
“Big Sky continues to deliver strong results for Musgrave. We are focusing on near-surface resource growth and exploring for both smaller high-grade deposits like White Heat in combination with larger near-surface but lower grade mineralisation like Big Sky.
“Both can potentially be mined by open pit methods and blended to maintain a steady rate of production.
“A 7,000m RC follow-up resource drilling programme at Big Sky has commenced. The drilling will focus on three zones of between 600m and 200m of continuous mineralised strike, with the aim of defining a near-surface gold resource to grow the total resource inventory at Cue. Drilling is ongoing and we look forward to updating the market with further results as assays are received.”
Big Sky Prospect
RC drilling south-west of Lena within the new 7km-long gold corridor continues to intersect significant gold mineralisation below thin transported cover (1-10m) in areas not drilled by previous explorers.
The Big Sky gold anomaly is defined over 2.6km of continuous strike. Infill resource definition RC drilling has commenced to test the continuity, grade and down dip extent of the mineralisation in oxide and fresh basement rock.
The Big Sky Prospect is approximately 2km south-west of Break of Day. A combination of Six-metre composite samples and one-metre individual samples have been received from a further 55 RC drill holes in the current program at Big Sky, with infill drilling underway to enable a maiden resource estimate in early 2022. Results for additional drilling are pending.
Significant new intersections at Big Sky include: 60m @ 1.0g/t Au from 42m; 6m @ 6.9g/t Au from 12m; 18m @ 1.1g/t Au from 36m; 12m @ 1.7g/t Au from 84m; 12m @ 1.6g/t Au from 48m; and 6m @ 2.2g/t Au from 30m.
The ongoing focus is on the higher grade and thicker intervals of gold mineralisation intersected to date. The extensive nature and continuity of the gold mineralisation supports the view that the Big Sky prospect has the potential to add to the company’s existing resource base at Cue.
