THE DRILL SERGEANT: Musgrave Minerals (ASX: MGV) reported the intersection of high-grade gold in a ‘link’ position joining the two main gold lodes at the Break of Day deposit on the company’s Cue gold project in Western Australia.
Musgrave Minerals recently completed a six-hole RC drill program at Break of Day that extended the high-grade gold mineralisation to the south as well as identifying a new high-grade ‘link-lode’ structure between the two main Twilight and Velvet gold lodes.
The company explained the identification of a high-grade ‘link-lode’ structure at Break of Day could hold some significance.
Linking structures are present in many Yilgarn gold deposits and have the potential to add lots of ounces and improve the economics of the deposits by increasing ounces per vertical metre within sections of the deposit.
Drill hole 19MORC037 was drilled to confirm a high-grade thicker section of the Break of Day system and test a new structural interpretation.
The hole identified a quartz dominant linking structure and gold lode assaying:
45 metres at 11.8 grams per tonne gold from 144m down hole, including 5m at 29.2g/t gold from 150m; and
23m at 16.2g/t gold from 166m.
Musgrave said it has yet to confirm the strike and plunge of the mineralisation in 19MORC037, which has made it difficult for the company to estimate the true width of the intersection at this time.
“Drill hole 19MORC037 (45m at 11.8g/t gold) was drilled to test a new hypothesis and structural interpretation and is a fantastic high-grade result for Break of Day on intersecting a potential new link-lode,” Musgrave Minerals managing director Rob Waugh said in the company’s announcement to the Australian Securities Exchange.
“This result opens numerous possibilities and opportunities to discover additional lodes and grow the Break of Day resource.
“Break of Day continues to deliver consistent high-grades and a few nice surprises.”
Drill hole 19MORC031 was drilled 35m south of previous drill hole 19MORC015 (2m at 9g/t gold) and returned a high-grade result of:
6m at 5.6g/t gold from 126m down hole in 6m composite samples.
Hole 19MORC033 intersected:
2m at 3.3g/t gold.
This was encountered 50m down dip of 19MORC015 and Musgrave has interpreted this to indicate the mineralisation continues at depth and is plunging to the south.
Musgrave is already planning additional follow-up drilling that will be scheduled for Q1 2020, which the company expects to lead to a resource update in Q2 2020.
The Break of Day area is excluded from the Earn-in and Exploration Joint Venture Musgrave has with Evolution Mining (ASX: EVN).
