IMC International Mining Corp. Confirms Copper Gold Showings and Plans Aggressive Drilling Program
During the summer of 2020, exploration fieldwork completed an 8-week field program that included Induced Polarization ("IP") surveying, petrographic studies, geological mapping, rock, soil and silt sampling with the objective of identifying prospective drill targets for the 2021 exploration season. The results reported in this release are from the Cathedral Area, which comprises approximately 11 sq. kilometers of the 206.58 sq. km Property.
Work at the Cathedral Area consisted of approximately 3.1 sq. kilometers of geological mapping, collection of 100 rock samples in support of the geological mapping program, 11 line-kilometers of IP surveying, collection of 507 soil samples along all IP lines and 6 samples submitted for petrographic study.
The Showings within the main zone of the Cathedral Area have returned up 13.90% Cu and 6.85 g/t Au from the Cathedral Showing, 4.72% Cu and 1.33 g/t Au from the Cathedral South Showing, 11.10% Cu and 2.77 g/t Au from the Arc Showing and 3.13 % Cu and 0.32 g/t Au from the Gully Showing.
Rock sampling undertaken during the 2020 work program was designed to support geological mapping, but significant results were returned. Selected results from grab samples that returned greater than 0.3 % Cu include:
Sample # | Cu % | Au g/t | Ag g/t | Sample Type |

Selected results from chip samples that returned greater than 0.3% Cu and/or greater than 0.2 g/t Au include:
Sample # | Width(m) | Cu % | Au g/t | Ag g/t |
2255 | 0.43 | 3.600 | 0.555 | 7.10 |

Styles of mineralization at the Cathedral Area include stockwork and disseminated porphyry-type and vein-hosted. Copper occurs as chalcopyrite and rare bornite. Late stage quartz veins containing high-grade gold values define the Pinncale Showing, located approximately 740 metres to the north of the main zone of the Cathedral Area. These veins have returned up to 20.10 g/t Au and 3.29% Cu.
Highly chargeable bodies of disseminated and fracture-controlled copper-gold mineralization appear proximal to and associated with an interpreted north-south trending moderately southeast dipping syenite. A tilted or off-set and possible hidden extension of a copper-gold alkalic porphyry system dominated by potassic, propylitic and sodic altered diorite, quartz monzonite/quartz monzodiorite intrusive phases is interpreted for the Cathedral Area.
Approximately 300 meters to the east of the syenite, in an area of cover, an IP anomaly that is approximately 500 meters wide by 1,000 meters long has the potential for a related blind porphyry system. This area contains a significant increase in chargeability and resistivity similar to increased features within the main showings of the Cathedral Area, which contained significant copper and gold mineralization. The chargeability extends to a minimum of 200 meters in depth and in areas where increased chargeability extends proximal to surface, anomalous copper-in-soil is observed.
The 2020 program was successful in gaining an understanding of the controls on the copper-gold mineralization and identifying areas to be tested by diamond drilling. Determining controls on mineralization was assisted by the development of a geological model for the drill ready areas, which has been interpreted to be a tilted alkalic porphyry. Figures illustrating the 2020 results are presented below.
IMC is planning an aggressive drilling program for 2021. A total of 6,150 meters of drilling has been identified to initially test the highly prospective targets identified during the 2020 work program. These targets have been identified from contingent geochemistry, geology and geophysics based on the following coincident criteria:
- Surface outcrop and sub-crop grab sampling from 2013 to 2020 of the Cathedral Area that has averaged 0.37 % Cu, 0.23 g/t Au, 1.26 g/t Ag in 442 samples;
- Time domain, pole-dipole IP resistivities of 1,000 background up to 2,500 ohm-m and
chargeabilities of 5.14 background up to 24.45mV/V;
- Soil sampling that has defined copper-gold-arsenic anomalies coincident with IP anomalies;
- Previously unmapped geology that is characterized by Duckling Creek Syenite Complex, which hosts the Lorraine Deposit located 18 kilometres to the south of the Cathedral Area; and
- Alkalic-porphyry related alteration and mineralization over an area of 4 sq. kilometers.
T. Greg Hawkins, P.Geo, Chairman of the Board of IMC, stated "Based on the exploration at the Cathedral Area to date, the area demonstrates a very strong potential for hosting (alkalic) porphyry style copper-gold mineralization, and we look forward to an extensive drilling program this coming exploration season on the Cathedral prospects as well as other areas within the Company's 206 sq. kilometer property."
All samples were transported by the exploration team manager. Rock samples were cut by rock saw with one half delivered to ALS Minerals (ALS) of North Vancouver, BC for sample preparation and analysis while the other half of the sample was retained for reference. Analysis consisted of multi-element ICP-MS and gold by fire assay with assays performed on over limits.
Further examination of data and sampling collected from other areas near the Cathedral Area will be reported in the near future.
