Surge Copper Expands Copper-Gold Mineralization at Ootsa Intersecting 108 Metres Grading 0.35% Copper Equivalent

Rhea-AI Summary

Surge Copper Corp. (SRGXF) has announced significant drilling results from its Ootsa Project, highlighting the expansion of copper-gold mineralization. The key findings include:

Hole S24-337 intersected 108 metres grading 0.35% CuEq (0.25% Cu, 0.16 g/t Au, 2.7 g/t Ag) from 24 metres depth, within a longer interval of 280 metres grading 0.27% CuEq. The deeper portion revealed multiple intervals of breccia-style mineralization with higher grades, including 10 metres grading 0.55% CuEq.

The drilling program, consisting of 2 holes totaling 897 metres, was conducted at the Cu-Au Target located 300 metres northeast of the East Seel deposit. While hole S24-336 did not extend the zone northward, hole S24-337 successfully expanded the zone to depth, with the exploration target remaining open to the east and west.

Positive

• Significant mineralization discovered: 108m at 0.35% CuEq from 24m depth
• Higher-grade intervals found in deeper portions: 10m at 0.55% CuEq
• Potential for meaningful resource expansion in the Ootsa Project area
• Zone remains open for expansion to east and west

Negative

• Hole S24-336 failed to extend mineralization to the north
• Large modeled magnetic anomaly at depth remains unexplained

Vancouver, British Columbia, Jan. 21, 2025 (GLOBE NEWSWIRE) -- Surge Copper Corp. (TSXV: SURG) (OTCQB: SRGXF) (Frankfurt: G6D2) (“Surge” or the “Company”) is pleased to announce assay results from drill holes S24-336 and 337, two exploration holes completed at the Company’s Ootsa Project at the end of the 2024 field season. The Company completed 2 holes for 897 metres of drilling at the Cu-Au Target located 300 metres northeast of the East Seel deposit and immediately north of the Seel Breccia East deposit which was partially delineated by the Company in 2022 (see February 7, 2023 news release). The 2024 drilling at the Cu-Au Target was designed to directly follow up on the discovery of copper-gold mineralization associated with quartz-magnetite-chalcopyrite veining identified in hole S22-330 which returned 100 metres grading 0.23% copper and 0.19 g/t gold (see January 9, 2023 news release). Drill targeting was also designed to test a large magnetic anomaly at depth.

Highlights

• Hole S24-337 intersected 108 metres grading 0.35% CuEq² (0.25% Cu, 0.16 g/t Au, 2.7 g/t Ag, and 0.003% Mo) from 24 metres depth within a longer interval of 280 metres grading 0.27% CuEq (0.20% Cu, 0.10 g/t Au, 3.5 g/t Ag, and 0.002% Mo) also from 24 metres depth (note: copper equivalent “CuEq” is reported net of by-product recoveries, please see Table 1, footnote 2 for details)

• The deeper portion of hole S24-337 encountered multiple intervals of breccia-style mineralization with higher grades of copper and silver, including 10 metres grading 0.55% CuEq (0.43% Cu, 13.94 g/t Ag, and 0.08 g/t Au) from 228 metres depth, and 10 metres grading 0.47% CuEq (0.39% Cu, 9.7 g/t Ag, and 0.05 g/t Au) from 264 metres depth

• These results combined with successful 2022 drilling done after the last resource estimate, show potential to significantly expand resources in this area

Leif Nilsson, Chief Executive Officer, commented: “We are pleased to have completed these drill holes at the Ootsa Project in 2024. While our primary focus remains on the Berg Project, following up on the 2022 discovery of copper-gold porphyry-style mineralization northeast of the East Seel zone at Ootsa presents a compelling exploration opportunity. This type of mineralization is particularly attractive for the Ootsa Project as it typically features higher-than-average grades, near-surface occurrence, and straightforward metallurgical characteristics. Successfully expanding the resource with this style of material could significantly enhance the potential of the Ootsa Project. While hole S24-336 did not extend the zone to the north in the tested area, hole S24-337 significantly expanded the zone to depth, and the exploration target remains open to the east and west. Additionally, the unexplained magnetic anomaly highlights further potential for step-outs to the north. Drilling at this copper-gold zone, alongside work in 2022 at the adjacent Seel Breccia East Zone, has occurred after the most recent resource cutoff, underscoring the opportunity for meaningful resource growth in this area of the Ootsa Project.”

Description of Exploration Holes S24-336 and S24-237

Hole S24-336 was oriented toward the north with a -80 degree dip and drilled to a total depth of 429 metres and was designed to constrain the northern margin of known copper-gold mineralization and test a magnetic-chargeability-resistivity geophysical anomaly. The hole encountered altered mainly coarse quartz porphyry intrusion from the start of bedrock at 9 metres depth, to the end of the hole at 429 metres depth. A zone of gold mineralization associated with quartz-pyrite veining returned 16 metres grading 0.30 g/t gold and 5.2 g/t silver from 22 metres depth. No other significant zones of mineralization were encountered in the hole and the large modeled magnetic anomaly at depth remains unexplained.

Hole S24-337 was a vertical hole drilled to 468 metres depth and was designed to assess the depth extent of the known copper-gold porphyry mineralization encountered in hole S22-330. The hole encountered 24 meters of overburden before hitting a mineralized semi-crowded feldspar-biotite-quartz porphyry with quartz-magnetite-chalcopyrite-pyrite veinlets along with remnant patches of potassium-feldspar and biotite alteration locally overprinted by chlorite and locally by clay alteration. Below 112 metres depth the hole contains increasing “Seel-Breccia” style mineralization characterized by quartz-carbonate veins and breccia matrix with variable proportions of chalcopyrite, pyrite, black sphalerite, and rare galena. The deeper parts of the hole encountered a mix of hornfelsed sedimentary rocks, mineralized feldspar-biotite-quartz porphyry, and unmineralized late quartz porphyry.

The hole returned 256 metres grading 0.27% copper equivalent (0.20% copper, 0.10 g/t gold, and 3.5 g/t silver) from the start of bedrock at 24 meters depth to 280 metres depth, including 108 metres grading 0.35% copper equivalent (0.25% copper, 0.16 g/t gold, and 2.7 g/t silver) from 24 meters depth to 132 metres depth. Mineralized zones encountered deeper in the hole include 10 metres grading 0.47% copper equivalant (0.39% copper, 0.05 g/t gold, and 9.7 g/t silver) from 228 to 238 metres depth, and 10 metres grading 0.55% copper equivalant (0.43% copper, 0.08 g/t gold, and 13.9 g/t silver) from 264 to 274 metres depth.

Hole S24-337 has significantly expanded known mineralization to depth, and these results combined with successful 2022 drilling done after the last resource estimate, show potential to significantly expand resources in this area.

Results from six additional core holes drilled during the 2024 program at the Berg Project, which were used for downhole geotechnical analysis, will be reported once laboratory analysis and reporting are complete.

Quality Control

All drill core is logged, photographed, and cut in half with a diamond saw. Half of the core is bagged and sent to ALS Geochemistry in Kamloops, British Columbia for analysis (which is ISO/IEC 17025 accredited), while the other half is archived and stored on site for verification and reference purposes. Gold is assayed using a 30g fire assay method and 33 additional elements are analyzed by Induced Coupled Plasma (ICP) utilizing a 4-acid digestion. Duplicate samples, blanks, and certified standards are included with every sample batch and then checked to ensure proper quality assurance and quality control.
