Alvo Minerals is off to a flying start with all seven holes from its maiden  10,000m drill program at the copper-zinc VMS Palma Project in Brazil, returning “exceptional results.”

Here are the big results from the C3 prospect:

  • 15m at 3.32% copper, 8.06% zinc, 0.34% lead, 31 g/t silver and 0.12 g/t gold from 258.85m, including 10.57m at 6.27% copper, 14.76% zinc, 0.17% lead, 39.98 g/t silver and 0.23 g/t gold from 267.47m;
  • 00m at 1.79% copper, 14.08% zinc, 0.23% lead, 17g/t silver and 0.11 g/t gold from 187m, including 9.00m at 2.86% copper, 17.22% zinc, 0.25% lead, 19.6 g/t silver and 0.09 g/t gold from 198m;
  • 21m at 2.19% copper, 7.84% zinc, 0.22% lead, 19 g/t silver and 0.11 g/t gold from 75.45m; and
  • 00m at 1.40% copper, 4.06% zinc, 0.53% lead, 35 g/t silver and 0.05 g/t gold from 222m, including 8.00m at 2.12% copper, 9.94% zinc, 1.32% lead, 86.4 g/t silver and 0.08 g/t gold from 224m.


Boost of confidence in C3

The company said the results are a strong confirmation of the mineralisation at the prospect and will increase confidence in an updated Mineral Resource Estimate.

Alvo Minerals (ASX:ALV) MD Rob Smakman said from the first hole they could see that C3 had the potential to be something special.

 Every hole has hit VMS mineralisation, some with exceptional grades and widths,” he said.

“Our primary aim of upgrading our confidence in the prospect has been met and the intercepts will keep coming.”

Surprise supergene copper

In hole PD3-012, the known mineralisation potentially expands at depth and is open down dip.

“The newly identified supergene mineralisation was a great surprise, with significant widths and grades of copper near surface that were previously unrecognised and unsampled in the historical drill core,” Smakman said.

“We are resampling historical drilling as well as redesigning our own ongoing exploration to see how extensive this new target can be.”



Supergene mineralisation involves the secondary enrichment of minerals due to the interaction of the sulphide minerals and meteoric waters.

In some cases, the supergene zone can form a blanket of mineralisation.

It’s the first time this type of mineralisation has been identified at C3 and Alvo is reviewing the historical work of the Geological Survey of Brazil (CPRM), and will re-sample any areas of interest.


Forward plan

Following the completion of drilling at the prospect, the two diamond rigs will move to C1 to test high priority extensional targets identified through the recent FLEM survey.

The company also plans to commence a FLEM survey at C3.
