High-Potential Porphyry Cu-Au-Mo Target Identified
BISHOPSGATE, UK / ACCESSWIRE / December 8, 2023 / SolGold (LSE:SOLG)(TSX:SOLG) is pleased to provide an update on its exploration activities at the Espejo Project ("Project"), part of the SolGold-ENAMI strategic exploration alliance ("SEA") in Northern Ecuador. The Espejo Project, situated approximately 20km northeast of the Company's Cascabel Project, has identified a promising porphyry Cu-Au-Mo target.
The Espejo Project, positioned within the Northern Andean Copper-Gold Belt, is located along the Toachi Fault. This fault is a deep-seated, arc-parallel tectonic structure bisecting the length of the Northern Ecuador Cordillera Occidental ("NECO") trend. The Project is in close proximity to the Company's Alpala and Tandayama-America porphyry copper-gold deposits. This region is renowned for hosting various major exploration projects and notable porphyry deposits such as SolGold's Cascabel (2.66Bt @ 0.37% Cu, 0.25 g/t Au) and Llurimagua (1.55Bt @ 0.51% Cu, 10 ppm Mo) (Figure 1).
SolGold's geological team, supported by expert advisors, believes the under-explored Toachi Fault zone in the NECO trend is a highly prospective area for the discovery of significant Cu, Cu-Au, and Cu-Mo porphyry deposits, alongside high-grade epithermal Ag and Au-Ag deposits.
Recent Developments at the Espejo Project
The Espejo Project now includes a newly identified porphyry Cu target at Anomaly 4, in addition to Anomalies 1, 2, and 3, initially characterized as three porphyry Cu targets (See News Release dated 28 June 2022 by Cornerstone Capital Resources Inc., now known as SolGold Canada Inc., ).
Recent exploration at Anomaly 4 has revealed a 2km x 1.5km area with porphyry intrusive rocks exhibiting Cu, Mo, and Cu/Zn soil geochemical anomalies (Figures 2-5). These findings include zones of outcropping B-type quartz veining within intrusive diorite and granodiorite rocks associated with biotite (± magnetite) potassic alteration overprinted by chlorite-sericite intermediate argillic alteration. Anomaly 4 also shows classic porphyry geochemical zonation, alteration, and mineralisation patterns, along with evidence of related epithermal and skarn Au-Ag systems. Rock sampling has yielded encouraging results, including significant Au, Ag, and Cu grades in various mineralized forms.
Rock sampling (Figure 6-9) assays yielded the following results, including significant grades of Au, Ag, and Cu in various mineralised forms:
multi-mineralic Au-Ag-Cu skarn: 4.15 g/t Au, 77.8 g/t Ag, and 2.63% Cu;multi-mineralic Au-Ag skarn: 34.5 g/t Au and 38.7 g/t Ag;magnetite-pyrite Au skarn: 10.80 g/t Au; andepithermal quartz veins: 36.8 g/t
Au.The four anomalies at Espejo have been delineated through geological mapping of rock types, alteration, and sulphide minerals and by multi-element soil geochemistry with rock geochemistry. The mineralisation discovered at Espejo suggests that anomalies 1-4 represent a cluster of porphyry systems warranting drill testing. The presence of porphyry-related epithermal and skarn mineralization suggests a potential source of intrusion or intrusions in the area.
Statement from the CEO
Scott Caldwell, CEO and President of SolGold Ecuador acknowledged the significant progress this year and the support from stakeholders:
"The recent identification of another high-potential target at the Espejo Project, coupled with our discovery at Blanca Nieves, highlights the expertise and commitment of our geology team. It also emphasizes the patience and trust shown by our stakeholders in 2023 while we carefully evaluated and prioritized SolGold's consolidated property list and effectively carried out our exploration program. My sincere thanks go to our team, whose exceptional work, combined with the collaborative spirit within SolGold, has been crucial in advancing our exploration projects. As we look ahead to 2024, we are filled with energy and optimism about the opportunities that lie before us. With the team's continued dedication and our shareholders' support, SolGold is well-positioned to explore these new frontiers and drive further
growth."

This is a location that hosts several growing exploration plays and the very large Cascabel (2.66Bt @ 0.37% Cu, 0.25 g/t Au) and Llurimagua (1.55Bt @ 0.51% Cu, 10 ppm Mo) porphyry deposits. This region promises to deliver significant portions of the copper and gold necessary to meet the growing global demand over the coming decades.
