Junior explorer Bellevue Gold (ASX: BGL) has announced high-grade results from a small program of reverse circulation drilling conducted over the shallow Tribune lode within the historic Bellevue gold project, 400 kilometres north-west of Kalgoorlie in Western Australia.
Exploration drilling at Tribune has been ongoing and is designed to infill the oxide and shallow broken zone over the JORC resource estimate area to assist in determining the best development option for accessing the project’s underground ore sources.
Results from the RC program of 25 holes for 1450 metres were in line with Bellevue’s expectations and support the interpretation of “gently southerly plunging oreshoots” within the overall north-west trending mineralised zone at Tribune.
Best assays returned were 5m at 17.3 grams per tonne gold from 46m including 2m at 40.8g/t gold from 44m; and 7m at 8.2g/t gold from 34m including 4m at 13.2g/t gold from 36m.
Other assays included 3m at 12.4g/t gold from 24m, 3m at 6.9g/t gold from 35m, 4m at 5.1g/t gold from surface and 7m at 2.8g/t gold from 13m.
Bellevue said it will conduct step-out drilling at Tribune to potentially extend the mineralisation along strike and at depth.
Executive director Steve Parsons said results to date confirm the quality of the Bellevue gold system.
“Our drilling so far demonstrates the high-grade nature of the mineralisation from surface, which bodes well for development access to an eventual underground operation,” he said.
Second discovery at Viago
Meanwhile, Bellevue continues to accelerate diamond drilling at the high-grade Viago lode, with a third rig expected to commence at the site next month to assist in drilling the central portion of the lode on a 80m x 80m drill pattern centred within the 800m strike length.
Earlier this month, Bellevue’s drill results over the area confirmed the significance of Viago, located in the Tribune Footwall below the historic Bellevue underground workings.
Currently not included in maiden resource estimates, the Viago lode is believed to be similar to the former mine’s high-grade bonanza oreshoots in geology, grades and width.
Assays returned to date have included 4.3m at 58.8g/t gold, 3.4m at 10.4g/t gold and 2.5m at 13.1g/t gold.
The results are expected to contribute to a Bellevue gold project resource estimate upgrade due later this year, adding to the JORC inferred resource announced earlier this month of 1.9 million tonnes at 8.2g/t gold for 500,000 ounces gold of JORC inferred resources.
Modern exploration techniques
During more than 100 years of operation, the Bellevue gold project became known as one of Australia’s highest-grade gold mines, producing more than 800,000oz at a reported head grade of 15g/t gold from a narrow vein operation.
Comprising approximately 1930km of the northern part of the Norseman-Wiluna Greenstone belt in WA’s Yilgarn Craton, the project was permanently closed in 1997 at 430m below surface.
Bellevue Gold is undertaking the first systematic exploration program at the property in the last 20 years.
The company believes the project provides an opportunity to apply modern exploration techniques to a historically-significant WA gold mine which is “poorly understood and underexplored”.
At midday, shares in Bellevue Gold were trading flat at $0.20.
