Catalyst Metals (ASX: CYL) and Navarre Minerals (ASX: NML) have hit a bonanza gold grade of 831 grams per tonne in drilling at the Tawry prospect within the Tandarra joint venture in Victoria.
A single diamond drill hole completed as follow-up to significant broad zones of gold mineralisation returned in earlier reconnaissance air core work made the “outstanding” intersection of 12.9 metres at 33.1g/t gold from 66.4m, including 0.5m at 831g/t.
It was located at an 8m zone of mineralised quartz breccia within a massive shale unit from 69m.
The breccia zone was oxidised and broken, with several sections of core loss in fault pug zones which Catalyst believes could contain further mineralisation.
Other highlights from the single hole were 1.0m at 2.5g/t gold from 153.5m; 1.0m at 1.2g/t gold from 173.4m; and 1.0m at 1.3g/t gold from 226.6m.
Previous wide-spaced reconnaissance drilling at Lawry returned assays of 20m at 1.5g/t gold from 56m; 1m at 10.5g/t gold from 86m; 9m at 2.0g/t gold from 57m; and 2m at 10.3g/t gold from 102m.
Reynolds trend
The Lawry prospect lies on the Reynolds trend — a lightly-explored structure located about 250m east of the main Tomorrow trend, which is the most advanced prospect at Tandarra.
Catalyst technical director Bruce Kay said assays show that Reynolds is also well mineralised and justifies an infill drilling program next field season.
“The extremely high grade gold intersection at shallow depth on the Lawry prospect means that there are now three parallel zones of gold mineralisation with high grades at the Tandarra project,” he said.
“This gold distribution is similar to that mined at the historic Bendigo goldfield which produced 22 million ounces of gold so we are excited to continue drilling next season.”
