EQS-News: New Results Boost Growth for Costa Fuego 31.10.2022, 13:00 Uhr von EQS News Jetzt kommentieren: 0

Four diamond drill holes completed for metallurgical testwork across the Productora resource in Q2 this year have returned further wide zones of copper, following analysis of remaining unsampled core.

Strong visual intersections of mineralisation in each of the metallurgical drill holes provided encouragement to undertake sampling of all remaining unsampled diamond core intervals.

Results for the first two holes of the programme (Productora central pit area and Alice satellite pit area) have delivered better than expected copper grades, including:

o 244m grading 0.8% CuEq (0.7% Cu & 0.2g/t Au) from 23m depth (MET025 – Productora)

including 71m grading 1.0% CuEq* (0.8% Cu, 0.2g/t Au)

o 152m grading 0.6% CuEq (0.6% Cu & 0.1g/t Au) from 42m depth (MET028 – Alice porphyry)

including 39m grading 1.1% CuEq* (1.0% Cu, 0.1g/t Au)

and 23m grading 0.9%CuEq (0.8% Cu) from 226m to end of hole

New results have added further high grade growth ahead of a planned resource upgrade for Costa Fuego. Productora and Alice have continued to demonstrate grade upside with in-fill drilling, providing positive reconciliation ahead of any future mining activities.

Entire hole results from the remaining two diamond holes at Productora (MET026 and MET027) are expected to be received in the coming weeks.

Results Returned from Valentina High Grade Satellite Resource Drilling

Valentina and its neighbouring San Antonio satellite copper deposit (Inferred resource of 4.2Mt grading 1.2%CuEq (1.1% Cu, 2.1g/t Ag) for 48kt Cu and 287koz Ag, reported March 2022) are located immediately to the east of Cortadera.

Results from an expanded drill program at Valentina have returned additional intersections of shallow copper sulphide and oxide mineralisation.

Highlights include:

o 3m grading 1.4% CuEq (1.3% Cu, 3.0g/t Ag) from 46m downhole (VAP0027)

o 6m grading 1.3% CuEq (1.3% Cu) from 10m downhole and 2m grading 1.1% CuEq (1.1% Cu) from 23m (VAP0029)

Of the four holes drilled in the expanded program, two recorded significant intersections, one intersected historic underground workings and one did not intersect the mineralised trend.

High grade copper-silver mineralisation at Valentina is currently defined over 300m and is open along strike and at depth.

A regulatory clearing application has been submitted to facilitate follow-up drilling at Valentina, which will expand resource drill definition across this potential high-impact future addition to Costa Fuego.

Phase One Drilling Complete at Santiago Z Intersects Wide Zones of Shallow Silver

Five deep Reverse Circulation (RC) drill holes for 2,146m were completed across the northern extent of the large-scale Santiago-Z porphyry target, lying approximately 5km south of the Cortadera resource (as reported to ASX 9th April 2021).

First-ever drilling on the 4km long by 2km wide porphyry footprint has not intersected any significant widths of copper mineralisation. However, drilling has recorded wide zones of silver mineralisation indicating a potential distal response to copper porphyry mineralisation.

Results for four of the five drill holes completed have been returned (results pending for SZP0005). Interesting drill results from Santiago Z so far include:

o 30m @ 4.5g/t Ag & 69ppm molybdenum (Mo) from surface (SZP0004) and 6m @ 0.1% Cu, 2.5g/t Ag, 37ppm Mo from 178m

o 38m @ 2.9g/t Ag, 20ppm Mo from surface (SZP0003)

including 14m @ 4.9g/t Ag & 9ppm Mo

Drilling encountered a sequence of intensely folded sandstones, limestones and carbonaceous limestone units with wide zones of significant pyrite mineralisation (1-2% pyrite logged) associated with hydrothermal breccias and thin tonalitic porphyry dykes (quartz-feldspar-phyric and typically 2 to 6m in down-hole width).

Molybdenum appears to be preferentially enriched over the area of drilling owing to the presence of carbonaceous limestone units, with higher grade silver mineralisation encountered toward the southern extent of drilling (SZP0003 and SZP0004).

An updated geological model is being created using RC chip logging and downhole multi-element geochemistry. This information will be used for any additional phases of exploration at the Santiago Z target.

Exploration will focus on the southern extent of the Santiago Z porphyry footprint in advance of any planned second-pass clearing and drilling activities.

* Copper Equivalent (CuEq) reported for the resource were calculated using the following formula: CuEq% = ((Cu% × Cu price 1% per tonne ×Cu_recovery) + (Mo ppm × Mo price per g/t × Mo_recovery) + (Au ppm × Au price per g/t × Au_recovery) + (Ag ppm × Ag price per g/t × Ag_recovery)) / (Cu price 1% per tonne × Cu_recovery).

The Metal Prices applied in the CuEq calculation were: Cu=3.00 USD/lb, Au=1,700 USD/oz, Mo=14 USD/lb, and Ag=20 USD/oz. Metallurgical recovery averages for each deposit consider Indicated + Inferred material and are weighted to combine sulphide flotation and oxide leachingperformance. The recovery and copper equivalent formula for each deposit is:

Cortadera and San Antonio – Weighted recoveries of 82% Cu, 55% Au, 82% Mo and 37%Ag. CuEq(%) = Cu(%) + 0.56 x Au(g/t) + 0.00046 x Mo(ppm) + 0.0043 x Ag(g/t)

Productora – Weighted recoveries of 84% Cu, 47% Au, 47% Mo and 0% Ag (not reported)CuEq(%) = Cu(%) + 0.46 x Au(g/t) + 0.00026 x Mo(ppm)

Costa Fuego – Weighted recoveries of 83% Cu, 53% Au, 69% Mo and 23% AgCuEq(%) = Cu(%) + 0.52 x Au(g/t) + 0.00039 x Mo(ppm) + 0.0027 x Ag(g/t)

Total Resource reported at +0.21% CuEq for open pit and +0.30% CuEq for underground.

* Copper Equivalent (CuEq) reported for the drillhole intersections were calculated using the following formula: CuEq% = ((Cu% × Cu price 1% per tonne × Cu_recovery) + (Mo ppm × Mo price per g/t × Mo_recovery) + (Au ppm × Au price per g/t × Au_recovery) + (Ag ppm × Ag price per g/t ×Ag_recovery)) / (Cu price 1% per tonne × Cu_recovery).

The Metal Prices applied in the calculation were: Cu=3.00 USD/lb, Au=1,700 USD/oz, Mo=14 USD/lb, and Ag=20 USD/oz. The entirety of theintersection is assumed as fresh. The recovery and copper equivalent formula for each deposit is:

Productora – Recoveries of 84% Cu, 47% Au, 47% Mo and 0% Ag (not reported).CuEq(%) = Cu(%) + 0.48 x Au(g/t) + 0.00026 x Mo(ppm)

For Productora, significant intersections are calculated above a nominal cut-off grade of 0.2% Cu. Where appropriate, significant intersections maycontain up to 30m down-hole distance of internal dilution (less than 0.2% Cu). Significant intersections are separated where internal dilution is greater than 30m down- hole distance. The selection of 0.2% Cu for significant intersection cut-off grade is aligned with marginal economic cut-offgrade for bulk tonnage polymetallic copper deposits of similar grade in Chile and elsewhere in the world. Down-hole significant intersection widths are estimated to be at or around true-widths of minerlisation.
