THE DRILL SERGEANT: Bellevue Gold (ASX: BGL) reported strike extensions to the Viago and Tribune Lodes within the company’s Bellevue gold project in Western Australia.
Recent drilling undertaken on the Tribune Lode has increased strike to over 1,000 metres where it remains open.
Bellevue Gold said the drilling encountered high-grade mineralisation in the Tribune Mineralised Shear, which has now been extended approximately 350 metres north of the original resource envelope (currently 650m of strike length) and a further 50m south and remains completely open.
Diamond drill core hole DRDD111 returned an intersection of 6m at 24.9 grams per tonne gold from 188 metres downhole indicating further high-grade ore shoots 350m to the north hosted in the Tribune Shear.
This intercept is in the hanging-wall to the historic Bellevue Mine while high-grade mineralisation has also been extended further south with the most southern hole drilled at Tribune.
This hole, DRDD112 intersected 6.5m at 22.2g/t gold from 96m down hole.
Bellevue explained the high-grade lode positions at Tribune are defined by plunging ore shoots controlled by fold axes within the shear zone.
These folds at Tribune have an analogous fold asymmetry and plunge lineation to mineralisation at the Bellevue lode located just 300m to the east.
Other drilling has confirmed the Viago Lode discovery by doubling its strike length to 1,400m also remaining open both north and south.
First pass broadly spaced diamond core drilling has extended the initial resource envelope of 750m strike length by approximately 550m to the north in the hanging wall of the Bellevue Mine and a further 200m to the south.
The previously reported Viago resource is 550,000 ounces at 22g/t gold of inferred category resources over a strike length of only 750m.
A downhole EM survey (DHEM) indicated the continuation of the EM plates into this area, which Bellevue says to be are largely untested.
The company said the DHEM plates are similar to what it had encountered during its first pass drilling when it discovered the Viago Lode.
Follow up drilling will now target these DHEM plates.
Five diamond drill core holes intersected the Viago Lode with visible fine-grained gold present in all drill holes.
The most northern hole (DRDD111) intersected 2.6m at 15.4g/t gold from 397.7m.
Hole DRDD128 intersected 2.4m at 15.4g/t gold from 445.4m.
Hole DRDD114 returned 4m at 14.8g/t gold from 544.6m.
To the south, Bellevue has extended the Viago Lode a further 200m with initial broad reconnaissance step-out drilling.
This drilling to the south has shown the Viago Shear to be more split than the northern Viago Shear, often into two or three mineralised shears associated within a much broader and strongly sheared zone.
Here diamond drill hole DRDD101 returned 3.9m at 8.1g/t gold, including 0.35m at 78.2g/t gold.
Hole DRDD120 returned 1.7m at 34.6g/t gold from 623.7m.
“Since the latest resource estimate upgrade at the ‘Bellevue Surrounds’ in January the drill rigs have moved from Bellevue Surrounds resource area and have commenced step-out extensional drilling at the Viago, Tribune and Bellevue Lodes,” Bellevue Gold managing director Steve Parsons said in the company’s announcement to the Australian Securities Exchange.
“We are extremely excited by this latest round of first pass step-out drill holes that confirm both Viago and Tribune Lodes extend a significant distance both north and south and also that the high-grade mineralisation remains open.
“The discovery of the Viago Lode continuing to the north is extremely encouraging and we are looking forward to the next phase of drilling that will infill and target the high priority DHEM conductors in this new mineralised area.
“There is a startling resemblance of the Viago North drilling to the initial drilling at the Viago discovery prior to the later infill drilling and drill testing of high tenor DHEM conductors.
“We are continuing with four diamond core drill rigs at site to target high priority DHEM targets at Viago North, resource definition as well as further step-out extension drilling at the Tribune, Viago & Bellevue Lodes.
“The company expects to update the Bellevue project resource estimate in the 2nd Quarter this year.
“Ongoing drill results continue to confirm that the Bellevue gold project is a globally significant high-grade gold discovery.”
