Geophysics Builds Targets Along the C4-A / C2-A Discovery Corridor Southeast of the Cabaçal Mine

Results from pole-dipole geophysical programs confirm basement targets flanking and along strike from the CD-139 discovery hole. Anomalies are also emerging in satellite positions associated with additional base and precious metal targets located further southeast in the C2-A corridor from ongoing programs.

The Company has continued its geophysical programs along the C4-A - C2-A corridor, having now completed 13-line kilometres of Pole-Dipole / Dipole-Dipole and 16-line kilometres of Gradient Array Induced Polarization (‘IP') surveys (Figure 2). The objective of the surveys has been to better prioritize targets based on geophysical responses, given significant concentrations of sulphides seen associated with the new discovery position in the southern sector of the C4-A target.

IP traverses over the original discovery area outlined basement chargeability anomalies with a threshold of up to 9.8mV/V. The chargeability response broadens and strengthens to the south, to peaks in the range of 11.3-15.9mV/V. This area has a flanking Worldview 3 satellite anomaly, marked by a silica-clay- jarosite-hematite signature. C2-A's soil response becomes progressively stronger in its base metal signature associated with the IP and Worldview3 anomalies (peak: Cu @ 500 ppm, Zn @ 418 ppm Zn; sample CAC4A-S-1640, and gold @ 402ppb Au).

The C2-A East Prospect was found as a result of Meridian's soil programs, in an area where there was no historical BP soil anomaly. It falls within a larger alteration response detected in Meridian's 2021 WorldView3 satellite survey, measuring 1200 x 650m. The alteration domain is centred around an area with >200ppm Cu in soil values, with a peak value of 1004 ppm (0.1%) Cu. Pole-Dipole surveys have confirmed a peak basement chargeability response of 16.7mV/V, with local Fixed-Loop EM anomalies with conductivity-thickness 815 Siemens. The geochemical and geophysical response is reminiscent of the signature over the alteration pipes of the Cabaçal Mine containing concentrations of disseminated to stringer and locally breccia to massive sulphide mineralization. Local float of quartz veins carrying sulphides (chalcopyrite and galena) have been observed, suggesting the influence of a late hydrothermal overprinting event in the area.
