Toronto, Ontario--(Newsfile Corp. - September 30, 2021) - C3 Metals Inc. (TSXV: CCCM) ("C3 Metals" or the "Company") is pleased to announce assays from a further seven holes from its ongoing drilling program at the Jasperoide Copper-Gold Project, Southern Peru. All seven holes were drilled on Line JAS2750 at the Montana de Cobre zone, located 50 metres north of high-grade copper-gold mineralization reported on Line JAS2700 (Press release dated September 8, 2021). Drilling continues to intersect high-grade copper-gold mineralization across the shallow dipping skarn domain that is laterally extensive for 400m to 600m and varies from 100m to 150m in true thickness.

Drilling at the Cresta Verde zone is progressing well, testing a high-priority coincident magnetic - IP anomaly located approximately 2 kilometres north-northwest of Montana de Cobre. The target measures 1200m by 600m and drill holes JAS4350-02 and JAS4350-03 intersected significant intervals of pervasive garnet-diopside-magnetite skarn alteration with up to 90% pyrrhotite and pyrite and with visible chalcopyrite mineralization. The JAS4350 drill collar is approximately 700 metres northwest of historical drill hole JADD11-20 which tested the southern extent of the anomaly and intersected 23.5m of 1.86% Cu¹ from 19m downhole.

Drilling Highlights:

• Copper-gold mineralization intersected over broad intervals on section JAS2750 includes:

JAS2750-05

• 229.45m @ 0.99% Cu and 0.43 g/t Au from surface
  
  including 23.44m @ 1.98% Cu and 0.96 g/t Au from 69.2m
  
  including 80.0m @ 1.89% Cu and 0.78 g/t Au from 130.4m

JAS2750-04

• 123.15m @ 1.28% Cu and 0.50 g/t Au from 66.1m

JAS2750-03

• 5.3m @ 0.56g/t Au, 2.91% Cu and 16.26g/t Ag from 101.3m

• Multiple porphyry vectors point to a causative intrusive source that is potentially central to the mineralization at Cresta Verde and Montaña de Cobre
• Assay results are pending for a further 10 drill holes
• Drilling is ongoing at the Cresta Verde Zone on section line JAS4050

Kevin Tomlinson, President & CEO of C3 Metals, commented,

"As we continue to define the high-grade oxide skarn at Montaña de Cobre we are very excited to be drilling the first coincident magnetic/IP geophysical target some 2 kilometres to the north at Cresta Verde. Our geologists have logged sulphide mineralization including chalcopyrite, together with molybdenite, associated with intense skarn development in two of the first three holes at Cresta Verde. Importantly these observations associated with a strongly coincident IP and magnetic anomaly together with the presence of high-sulphidation feeder structures and chalcopyrite-bearing porphyry fragments are indicative of proximity to a causative porphyry intrusion.

Jasperoide displays all the characteristics of a large mineral system with kilometre-scale copper skarn development associated with major structures and multi-phase intrusions. Over 80% of historical holes were drilled to less than 250m depth, just touching the surface of this large-scale hydrothermal system. We are very encouraged by the drill results to date and look forward to further drilling to evaluate and develop the full potential of the property."

A total of 34 drill holes have been completed to date with drilling now progressing on Line JAS4050 (Figure 1).

Drilling on Line JAS2750 demonstrates that skarn alteration and copper-gold mineralization thicken to the northeast, where drill holes JAS2750-04, 05, 06 and 07 intersected pervasive garnet diopside and magnetite skarn that is strongly oxidized to over 200m in depth. Secondary copper species comprise malachite, chrysocolla and azurite, occurring as disseminations, infill and in cm-scale veins (Figure 3).

The most westerly drill fan (JAS2750-01 and 02) intersected narrow zones of skarn mineralization with the best interval assaying 16.75m @ 1.36% Cu and 0.47g/t Au in JAS2750-01.

Drill hole JAS2750-03 intersected multiple high-sulfidation (acid) epithermal veins similar to drill hole JAS2700-04 (Press release dated September 8, 2021), with the best assay being 16.55m @ 1.60% Cu and 0.58g/t Au. Multiple cavities were encountered in this hole which was stopped short of target depth.

Notes:

1. Significant intercepts are reported as length-weighted averages exceeding 0.20% Cu, with less than 5m of consecutive internal dilution.
2. Arbitrary top cut of 5g/t on gold assays has been used, copper is uncut.
3. True width of down-hole intersections reported are estimated to be approximately 60-90% of the down-hole lengths.

Cresta Verde Drilling

The Company recently completed airborne magnetic and ground IP surveys across the permitted area, defining several coincident magnetic (Figure 1) and IP chargeability anomalies (Figure 4). Modelling and inversion of the geophysics data indicates the magnetic and IP chargeability anomalies strengthen with depth and therefore represent compelling drill targets.

Three holes were completed at Cresta Verde approximately 2km to the north of Montaña de Cobre on Line JAS4350, for a total of 1429.1 metres. The holes were targeted on large-scale and cohesive IP chargeability and magnetic anomalies defined from the recently completed ground IP and airborne magnetic surveys (Figures 1 and 4).

JAS4350-01 drilled northeast (065 degrees azimuth) and was designed to test a large north-south oriented magnetic anomaly. The hole intersected a multi-stage intrusive complex that is locally endoskarn altered and is cut locally by sulphide veinlets.

JAS4350-02 drilled southwest (245 degrees azimuth) and tested a separate target comprising a coincident magnetic and IP chargeability anomaly measuring 1200m by 600m. Moderate to strong skarn alteration with significant sulphide mineralization was intersected from surface to 330m depth. A hydrothermal breccia with a massive sulphide matrix was intersected from 260m to 310m depth. The breccia zone contains up to 90% sulphides that are dominated by pyrrhotite and pyrite, overprinted by late-stage chalcopyrite and molybdenite mineralization (Figure 5). From 330m to the end of the hole at 705.5m is equigranular diorite cut by millimetre to metre-scale pyrrhotite veins with chalcopyrite along vein selvages. The hole was terminated in mineralization due to rig capacity.

JAS4350-03 intersected strong skarn alteration from surface to the end of the hole, containing significant pyrite and pyrrhotite mineralization with later-stage chalcopyrite as infill. This hole was abandoned at 381m depth after intersecting a large north-south fault.

Drilling is progressing on Line JAS4050 to test for southern extensions to the large-scale coincident IP chargeability and magnetic anomaly. The hole is drilling southeast and intersected massive magnetite skarn with significant pyrite and visible chalcopyrite mineralization from 100m depth and is currently at 210m depth.

Summary

Drilling at Montaña de Cobre continues to demonstrate that the mineralized skarn is significantly oxidized to over 200m depth and is laterally extensive for over 400 metres on Lines JAS2650, JAS2700 and JAS2750. Copper mineralization is dominated by secondary copper species and drilling continues to confirm broad intervals of high-grade copper-gold mineralization at the northeast area of the Montaña de Cobre zone.

The recently completed 1,800 line kilometre helicopter-borne magnetic / radiometric survey and a 43 line kilometre ground Induced Polarisation (IP) survey has identified four large scale and coincident magnetic and IP Chargeability anomalies within the permitted area. Drill holes JAS4350-02 & 03 both intersected significant sulphides that are coincident with the largest IP Chargeability anomaly, located at Cresta Verde zone. A review of the 3D IP model indicates chargeability anomalies converge at depth and demonstrate a cohesive system of high chargeability that is centrally located between the Cresta Verde and Montana de Cobre zones, representing a compelling drill target.

Drilling and exploration studies continue to support the interpretation of a concealed porphyry copper system at depth, with important vectors including:

• Porphyry style alteration and veining
• Coincident magnetic and IP chargeability anomalies
• Mineralized porphyry fragments
• Sulphide veining with late-stage chalcopyrite
• High-sulphidation feeder structures
• Molybdenite mineralization

The Company is awaiting results from soil sampling and surface mapping programs which are expected to aid in the design of deeper drill holes to target interpreted stacked skarns and an interpreted concealed porphyry system at depth.

Additional results will be released as they become available. Assays are pending for all three holes on Line JAS4350 and the rig is currently positioned on Line JAS4050.
