C3 METALS COMPLETES DISTRICT SCALE 3DIP SURVEY OVER THE BELLAS GATE PROJECT, JAMAICA; CONFIRMS MULTIPLE DEEP-SEATED PORPHYRY TARGETS

C3 Metals Inc. has completed a large-scale, 3-D electrical geophysical (induced polarization) survey at the company's 100-per-cent-owned Bellas Gate project in Jamaica. 3-D IP is an advanced subsurface mapping method measuring electrical properties of the geology at significant depths, an important technique applied to deeper porphyry copper and gold exploration.

The 3-D IP survey covered an area of over 80 square kilometres over two northwest-/southeast-trending porphyry belts confirmed in previous drilling at the Bellas Gate project. Previous drill results on these two porphyry belts includes:

• Connors porphyry prospect (see press releases dated Sept. 12, 2022, and May 15, 2024):
  • 309.0 metres at 0.44 per cent copper and 0.33 gram per tonne gold from 15 m downhole depth;
  • 79.0 m at 0.71 per cent copper and 0.49 g/t gold from 128 m downhole depth, including 46.0 m at 0.95 per cent copper and 0.69 g/t gold;
• Camel porphyry prospect (see press releases dated Nov. 28, 2022, Oct. 4, 2023, and June 5, 2024):
  • 178.5 m at 0.37 per cent copper and 0.16 g/t gold from 10 m downhole depth;
  • 108.0 m at 0.42 per cent copper and 0.26 g/t gold from six m downhole depth;
  • 207.8 m at 0.43 per cent copper and 0.20 g/t gold from 22 m downhole depth, including 135.0 m at 0.52 per cent copper and 0.27 g/t gold;
  • 294.0 m at 0.30 per cent copper and 0.13 g/t gold from nine m downhole depth;
• Provost porphyry prospect (see press releases dated Sept. 12, 2023, and Nov. 27, 2023):
  • 285.9 m at 0.37 per cent copper and 0.21 g/t gold from 64 m downhole depth;
  • 92.0 m at 0.24 per cent copper and 0.12 g/t gold from 60 m downhole depth;
  • 280.7 m at 0.37 per cent copper and 0.21 g/t gold from 227 m downhole depth, including 61.7 m at 0.50 per cent copper and 0.39 g/t gold;
  • 170.1 m at 0.31 per cent copper and 0.16 g/t gold from 68 m downhole depth.

Bellas Gate, Jamaica 3-D IP survey highlights:

• The 3-D IP survey was highly successful in identifying multiple, deep-rooted chargeability anomalies that are coincident with broad zones of porphyry-style alteration and mineralization at surface, in particular at the Provost, Kola and Lucky Valley prospects.
• Inversion of the 3-D IP data defines two well-developed, northwest-southeast-trending chargeability anomalies that parallel the Connors and Camel Hill porphyry belts, with the strongest chargeability anomalies covering the Provost, Kola and Lucky Valley prospects.
• In the southeastern project area, the 3-D IP survey was extended to cover the Kola prospect, which confirmed a new, large chargeability anomaly that is now slated for drill testing.
• The company has evaluated and ranked surface and geophysical data for each of the main prospects and designed a drill program of up to 11 holes totalling 10,800 m. This program is anticipated to commence in October, 2026, and be completed by April, 2027.

Dan Symons, president and chief executive officer, stated: "The Bellas Gate project hosts multiple high-level porphyries that remain open at depth. Numerous drill holes from previous programs ended in copper/gold mineralization. The potential of the high-grade cores of these known porphyries requires deeper drilling. Investing in this 3-D IP survey to obtain deeper-penetrating, high-quality chargeability and conductivity data prior to deeper drilling enables us to more accurately plan and prioritize our drill holes. The 3-D IP data allows us to rate and rank prospects by better defining which porphyries have favourable deep-rooted anomalies. The survey also generated several new prospects where there are strong 3-D IP anomalies. We anticipate deep drilling will commence early in the fourth quarter of 2026."

The Bellas Gate project comprises three separate special exclusive prospecting licences and totals 13,020 hectares. On Feb. 11, 2025, the company announced it had entered into an earn-in agreement with Freeport-McMoRan Exploration Corp., a wholly owned affiliate of Freeport-McMoRan Inc., whereby Freeport can earn up to 75 per cent in the project by financing up to $75-million (U.S.) in exploration and project-related expenditures (see press release dated Feb. 11, 2025).

The completed 3-D IP survey covered the Provost, Camel Hill and Connors porphyry systems, together with other priority porphyry targets across the Bellas Gate project area. The program consisted of two 3-D DC-resistivity and induced polarization survey areas, Arthurs Seat and Bellas Gate, acquired with a rolling distributed 3-D receiver array operating in common voltage reference mode. The Arthurs Seat block included four receiver lines and three transmitter lines, with line lengths ranging from approximately 8.3 km to 9.0 km. The Bellas Gate block included 19 receiver lines and 18 transmitter lines, with line lengths ranging from approximately 2.5 km to 7.5 km. Across the 3-D grids, receiver and transmitter lines were spaced at 600 m, receiver stations were spaced at 250 m, and transmitter stations were spaced at 500 m. The completed 3-D survey covered approximately 82.5 square kilometres and included approximately 167 line kilometres of receiver coverage and 158 line kilometres of transmitter coverage, generating a high-density, multiazimuth data set for 3-D resistivity and chargeability inversion modelling to an approximate depth of investigation of 1,000 m.

Two chargeability inversion models were produced from the survey data: one by Dias Geophysical (which conducted the 3-D IP survey) and one by Bolin Geophysical Services. Both models correlate well. The chargeability models have been fully integrated with a new magnetic inversion model. All surface data and the chargeability anomalies show a strong correlation with known porphyry centres.

Next steps

The 3-D IP survey confirmed multiple, strong chargeability anomalies along the two known porphyry belts. After a review of these data concurrently with all existing surface and subsurface data, an 11-hole, 10,800-metre diamond drill program has been designed to test the highest-priority geophysical anomalies supported by geological and other geophysics survey data (for example, airborne magnetics, surface alteration and geochemistry).

An example of a high-priority drill target is the Provost porphyry prospect, where deep drilling will test beneath known mineralization identified in previous drilling and where both chargeability and magnetic inversion models show deep-rooted anomalies.

At Jasperoide, the company has identified over 13 skarn prospects and two porphyry prospects over two parallel 28-kilometre belts. The company has published a maiden resource estimate on the first of these skarn targets, which contained measured and indicated resources of 52 million tonnes at 0.5 per cent copper and 0.2 g/t gold. The company is also actively exploring in Jamaica, where it has identified 16 porphyry, 40 epithermal and multiple volcanic red-bed copper prospects over a 30-kilometre strike extent. The company holds a 100-per-cent interest in 17,855 hectares of exploration licences, of which Freeport-McMoRan Exploration Corp., a wholly owned affiliate of Freeport-McMoRan Inc., has the option on 13,020 hectares to earn up to a 75-per-cent interest by financing up to $75-million (U.S.) of exploration and project-related expenditures. The company also holds a 50-per-cent interest in 9,870 hectares in a joint venture with Geophysx Jamaica Ltd., the largest mineral tenure holder in the country. Barrick Mining Corp. announced on May 1, 2024, that it had entered into an earn-in agreement with Geophysx Jamaica on approximately 400,000 hectares of exploration licences, several of which surround C3 Metals' mineral concessions. Mining is currently the second-largest industry in Jamaica, and historical mining dates back to the colonial eras of the 1500s (Spanish) and 1800s (British).
