Croydon project reveals indium potential

Croydon project reveals indium potential

A fresh look at samples from Crater Gold Mining’s Croydon polymetallic project in North-West Queensland has revealed high levels of the critical mineral indium.

The company has released results showing very high indium assays
up to 190.0 ppm.

These were obtained from the re-assay of six selected intervals from
three drill holes drilled in 2006/07 at ‘Anomaly A2’ at the polymetallic project, Crater said.

A very high silver value of 2250 g/t (0.225 per cent) was also
obtained from a 0.75m interval from a drillhole.

“In view of this encouraging result, indium will now be routinely assayed for by Australian Laboratory Services (ALS) using their ME-MS61 method for all upcoming drilling programs in the polymetallic project area,” managing director Russ Parker said in a statement to the ASX.

“The rationale for the check assaying was based on the known association of anomalous indium (often together with Ga and Ge) in zinc, tin and copper polymetallic mineralisation similar to that intersected at Anomaly A2.”

Indium (In) is a rare metal that is used in semiconductor industry applications such as LCD displays, solar panels, microchips and emerging green energy photovoltaic cell technologies.
