The Macnaughtan prospect – part of Navarre’s ‘Tandarra’ JV – is now 1,100m long after drilling hit more bonanza grades of up to 112g/t gold.

The Tandarra Gold Project, a joint venture (JV) between Navarre Minerals (ASX:NML) 49%, and Catalyst Metals (ASX:CYL) 51%, continues to deliver strong gold results in recently completed drilling.  The Project sits along the ‘Whitelaw Fault’ — the major structural control of gold mineralisation at the historic Bendigo Goldfield, which produced 22 million ounces of gold at an average grade of 15g/t gold.

This fault line has been traced further north into the JV ground, concealed below a blanket of younger Murray Basin cover.

New drilling results reported to the ASX continue to grow Tandarra’s potential for discovery of a large, high grade gold system – like Fosterville or Bendigo.

Results of a 60-hole, 6,764m air core drilling program on the ‘Macnaughtan’ and ‘Lawry’ prospects and an 11-hole, 3,800m diamond/reverse circulation (RC) drilling program at Macnaughtan and ‘Tomorrow’ prospects at Tandarra JV are now in.


At Macnaughtan, drilling has extended the strike extent of the gold trend by an additional 100 metres for a total length of 1.1km, remaining open along strike.

The best gold hit was in Hole TNA050 which contained two significant intersections:

  • 9 metres @ 14.8g/t gold, including 1 metre @ 112g/t gold from 106 metres, and
  • 10 metres @ 1.7g/t gold from 119 metres.

At the adjacent Tomorrow Line, a nine-hole program of diamond drilling and RC drilling was completed, testing depth extensions of the ‘Tomorrow’ zone up to 500 metres below surface.

It returned a best intercept of 3 metres @ 13.8g/t gold from 202m.

“The Macnaughtan Line has emerged as a second zone of gold mineralisation with high grades intersected in both diamond and air core drilling over a strike length of more than 1,000 metres,” Catalyst technical director Bruce Kay says.

“Further gold intersections at ‘Tomorrow’ support the presence of repeat structures that could be mined by underground methods.”

Drilling activities have ended for the 2021 field season and will resume in December 2021 / January 2022 after crops have been harvested.
