Metallica Metals Commences Surface Exploration Program at Sammy Ridgeline Ni-Cu-PGM Project

Vancouver, British Columbia--(Newsfile Corp. - August 9, 2022) - Metallica Metals Corp. (CSE: MM) (OTCQB: MTALF) (FSE: SY7P) (the "Company" or "Metallica Metals") is pleased to announce that field mapping and prospecting work has commenced on the Ni-Cu-PGM Sammy Ridgeline Project ("Sammy Ridgeline" or the "Project") in the Thunder Bay North District of Ontario, Canada. Sammy Ridgeline is located approximately 50 km northeast of Thunder Bay, with the two claim blocks lying on either side of Clean Air Metal's Thunder Bay North Project (Figure 1). The exploration program is scheduled to run until the end of the summer field season and will consist of geological and structural mapping, grab and channel sampling, and possible trenching. The Project has numerous showings and mineral occurrences comprised of molybdenum, copper, zinc, lead, silver, tin, tungsten and uranium, but was never previously explored for platinum and palladium (PGM's). The field program will largely focus on confirming PGM geophysical exploration targets that were developed from a detailed study using data from the 2021 MobileMT airborne survey (refer to the Company's news release dated May 16, 2022).

Exploration Program Summary:

  • Completing prospecting and geological mapping across the entirety of the two Sammy Ridgeline claim blocks and sampling any mineral occurrences (Figure 2). An exploration permit has been submitted to the Ontario Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF) to complete trenching work and is pending approval.

  • The field program will focus on eleven Ni-Cu-PGM targets generated across the combined East and West blocks (see Figures 3 and 4). Of particular interest are targets displaying remanent magnetism, which can be a feature of PGM deposits, that also have important structures in close proximity.

  • Revisiting existing showings and mineral occurrences to evaluate their potential for further exploration and drilling targets.

  • Any geophysical targets buried under thick overburden cover may be trenched to expose the bedrock to map the geology and collect grab and channel samples.

Aaron Stone, CEO of Metallica Metals commented, "The Metallica Metals team is excited to have commenced the Company's inaugural surface exploration program on its Sammy Ridgeline Project. The property is located only 50 km from the major hub of Thunder Bay and on either side of Clean Air Metals' significant Thunder Bay North PGM discovery. The project boasts ease of access with a strong road network already in place, and outcropping geology is plentiful across the two blocks, which bodes well for exploration. Metallica Metals is very happy with the competent local team we've assembled to complete the exploration program at Sammy Ridgeline. We look forward to seeing the results from this mapping and prospecting program".

A local Thunder Bay geologist with over 20 years of industry experience has been engaged by Metallica Metals to oversee the Sammy Ridgeline exploration program with assistance from a local field technician. With a strong set of data in hand, the Company is confident in the exploration potential of the Sammy Ridgeline Project.

Mineral Resource Estimate Sources and Cautionary Statements: The Sammy Ridgeline Project is contiguous to the Clean Air Metals Thunder Bay North Project. The Thunder Bay North Project is host to two significant deposits, Current Lake and Escape Lake, which together comprise an underground-constrained mineral resource estimate with an Indicated Resource of 14.5 million tonnes at 1.58 g/t Pt and 1.54 g/t Pd (8.12 g/t PtEq) and an Inferred Resource of 8.1 million tonnes at 0.67 g/t Pt and 0.69 g/t Pd (4.07 g/t PtEq) (MRE source: NI 43-101 Technical Report on the Thunder Bay North Project, Northern Ontario, Canada with an effective date of December 1, 2021 and filed on SEDAR under Clean Air Metals Inc.). The Sammy Ridgeline Project is also adjacent to the Impala Canada Lac des Iles PGM Mine. The Lac des Iles Mine contains proven and probable mineral reserves of 40.9 Mt at an average grade of 2.31 g/t Pd for 3.04 Moz of contained Pd (MRE source: NI 43-101 Technical Report on the Feasibility Study for Lac des Iles Mine with an effective date of July 4, 2018 and filed on SEDAR under Impala Canada Ltd.). Readers are cautioned that mineralization and mineral resource and mineral reserve estimates on adjacent and/or nearby properties are not necessarily indicative of mineralization on the Sammy Ridgeline Project (please refer to additional cautionary statements below).
