Marimaca Copper begins 2022 drilling at Marimaca oxide deposit in Chile

TSX-listed Marimaca Copper has announced the start of an infill drilling campaign at the Marimaca oxide deposit in Northern Chile near Antofagasta, while planning for a depth extension drill programme at another area of the project is close to being finalised.

The explorer has completed the first five drill holes of a 22,500 metres infill drill programme, which aims to convert existing inferred resources to measured and indicated ahead of a mid-year mineral resource estimate. The update will then form the basis for a feasibility study in the second half of 2022.

Additional drill rigs are expected to be added in the coming weeks for the recently discovered MAMIX zone. The infill campaign will be increased from 2,500 metres to up to 10,000 metres following a positive metallurgical review of the target.

“The discovery of the MAMIX zone offers outstanding potential to increase the overall scale of the Marimaca project,” said Marimaca’s VP exploration Sergio Rivera. “We recently released an exploration target to quantify the potential size of this opportunity and we intend to test it as part of the expanded MOD infill programme.”

Meanwhile president and CEO Hayden Locke said: “We are now very focused on the upside potential at Marimaca. Our internal work indicates that MAMIX presents a compelling opportunity to increase the scale of the deposit, both in terms of contained metal tonnes and potential annual production, which will be used as the basis for the feasibility study.”
