During the fourth quarter of 2020, the contractor completed the reverse circulation drilling program, including 14 holes from the 300 series and six holes from the 200 series.

Currently, partial assays for visible copper mineralisation have been reported from the 200 series, with up to 4.1 per cent of copper confirmed. Meanwhile, for the 300 series, visible copper mineralisation has been confirmed for six drill holes.

The full assay results for all twenty holes will be reported very shortly in two to three batches.

Castillo has sped up plans for the first half of 2021 because geological interpretations of the current and historical data from Mt Oxide have suggested a shallow, high-grade, scalable copper system.

These plans include a geophysical survey to identify potential massive sulphide bedrock conductors that could extend known mineralisation and finishing the current reverse circulation (RC) drilling campaign.

"Overall, the board is delighted with the progress of the drilling campaign to date and will keep shareholders informed of news as it materialises," the company told the market.

On market close, Castillo is up 8.57 per cent and trading at 3.8 cents per share.
