Marimaca Copper (MARI) has reported results from 10 reverse circulation drill holes, totalling 3,320m, from the 2022 infill drilling campaign at the Marimaca Oxide Deposit.

The drilling intersected broad zones of near-surface green copper oxide mineralization in all holes.

As with the first infill results, these holes confirmed the mineralized zones as interpreted in the existing Mineral Resource Estimate (MRE) area for the MOD.

Still, several zones encountered higher grades than expected.

Furthermore, several intercepts were extensional, falling outside the 2019 MRE block model, with positive implications for future resource updates.

Some highlights include how some drill holes display excellent continuity of mineralization and are in line with the interpretations expected from MRE model.

LAR-87 intersected a broad zone of mineralization outside the south-western limit of MRE block model.

Drilling continues to highlight the lateral continuity and thickness of the MOD mineralized column and the continuing potential for higher grade extensions at depth.

Sergio Rivera, VP of exploration of Marimaca Copper, commented, “These ten drill holes from our infill campaign have continued to highlight the excellent continuity of mineralization at the MOD.”

“We intersected the expected mineralization in all holes. Of note were several areas with grades exceeding those expected in the MRE models, which we anticipate would positively impact our future resource estimations,” added Rivera.

Marimaca’s 2022 drilling campaign consists of 22,500 m of planned infill drilling of the MOD and an additional 10,000 m of drilling of the MAMIX zone, the depth extension of the MOD.

The objective of these programs is to convert the MOD’s existing inferred resources to Measured and Indicated categories and grow the M&I resource inventory through infill drilling of the MAMIX discovery made in 2021.

The initial results of the infill program extended the known mineralized envelope, especially along the southern margin of the deposit and encountered grades above those interpreted in previous MREs.

This is expected to positively impact the MRE update in the second half of 2022.

The current results have confirmed the geological and resource modelling, with mineralization encountered in the common areas.

Once again, there have been positive surprises. Several zones encountered grades exceeding expectations in the MRE models and interpretation, with zones extending well beyond the previously interpreted mineralized envelope.

Drill holes LAR-85, LAR-86 and LAR-87 are located on the south-western limit of the MRE, which was previously interpreted to be of lower grade and limited resource expansion opportunities.

LAR-87, which intersected a broad zone of mineralization from the surface, is particularly interesting.

Based on the MRE interpretation, it is expected that this intercept will provide a good basis for further resource growth towards the southwest, outside of the current MRE area limits.

Additionally, the higher-grade zones encountered at the bottom of the drill hole are interpreted as a northern extension of the previously discovered MAMIX zone.

The results again confirm the excellent lateral and vertical continuity of mineralization and confirm the previous interpretations of mineralization, which underpins the 2019 MRE.

The updated Mineral Resource Estimate is planned for early Q3 2022, immediately following the completion of the current drilling program.

Marimaca Copper Corp.  (MARI) is down 1.45 per cent, trading at C$3.40 at 12:43 pm ET.
