Murchison Minerals Confirms Broad Intervals of Ni-Cu-Co Sulphide Mineralization at the PYC Target on the HPM Project - Receives First Batch of Assay Results
March 7th, 2022 (Burlington, ON): Murchison Minerals Ltd. (“Murchison” or the “Company”) (TSXV: MUR, OTCQB: MURMF) is pleased to announce the first assay results from the inaugural drill program at the PYC Target on the 100% - owned 576 km2 HPM (Haut-Plateau de la Manicouagan) Project, located in Quebec. The assay results for drill holes PYC21-007 & 008 come from the PYC target – a large, 1.95 km EM anomaly that was identified in the summer of 2021 as a target for bulk-tonnage low-grade magmatic sulphide mineralization. The results from the first two holes confirm extensive shallow nickel, copper, and cobalt sulphide mineralization, the area remains open at depth and along strike. Samples from the remaining six holes are still at the lab, and the Company is eagerly awaiting the results.
- Successful confirmation of Murchison’s systematic exploration approach utilizing airborne electromagnetic (EM) survey methods to identify conductive anomalies that potentially correspond to metal-rich sulphide, beep-mat surveying and backpack drilling to evaluate anomalies for near-surface Ni-Cu-Co mineralization, followed by diamond drilling to test the depth extent of mineralization
- Modern VTEM survey covers approximately 15% of the 576 km2 HPM Project from which 50 EM anomalies have been interpreted. These targets range from bulk-tonnage low-grade targets like PYC through to high-grade showings like Barre de Fer, located only 1.5 km away (best historic results from HPM-08-03 of 43.15 m at 1.73% Ni, 0.90% Cu, and 0.09% Co)
- The PYC drilling results, when paired with those from the historical work and the prospecting completed at Barre De Fer and Syrah, confirm the presence of an extensive Ni-Cu-Co bearing magmatic sulphide system at the HPM Project
- Hole PYC21-007 drilled to a depth of 158 m intersected three broad zones of Ni-Cu-Co-bearing sulphide mineralization totalling 62.21 m of composite thickness (Table 1), including:
- 25.5 m grading 0.30% Ni Eq (72.5 m to 98.0 m) including 8.6 m at 0.49% Ni Eq (78.4 m to 87.0 m) and 0.96% Ni Eq over 1.57 m (85.43 m to 87.0 m at 0.57% Ni, 0.19% Cu, and 0.11% Co)
- 27.41 m grading 0.23% Ni Eq (3.24 m to 30.65 m) including 1.8 m at 0.52% Ni Eq (3.8 m to 5.6 m)
- Hole PYC21-008 drilled to a depth of 182 m intersected five broad zones of Ni-Cu-Co bearing sulphide mineralization totalling 69.9 m of composite thickness (Table 1), including:
- 39.5 m grading 0.24% Ni Eq (5.5 m to 45.0 m) including 7.6 m at 0.37% Ni Eq (25.4 m to 33.0 m) and 1.26% Ni Eq over 0.58 m (43.08 m to 43.66 m at 0.76% Ni, 0.11% Cu, and 0.16% Co)
- 13.0 m grading 0.27% Ni Eq (From 75.0 m to 88.0 m) including 1.47% Ni Eq over 0.7 m (76.6 m to 77.3 m at 0.88 Ni, 0.21% Cu, and 0.17% Co)
- The bulk of mineralization in holes PYC21-007 & 008 comprises two broad, parallel lens of Ni-Cu-Co sulphide mineralization hosted in a fine-grained dark-coloured micro-gabbro, separated by approximately 30 metres of unmineralized gabbro
- Assay results are pending for the remaining six holes which tested 0.55 km of the 1.95 km total strike length at the PYC target. Holes PYC21-007 & 008 were completed towards south-east end of the VTEM anomaly
- The PYC Target is only one of multiple Ni-Cu-Co prospects on the 100% – owned HPM Project, which is strategically located 8 km from a rail line and within 30 km of Hart-Jaune hydroelectric power generating facility – located in Quebec, one of the world’s most stable and best mining jurisdictions

”The price of nickel is at decade highs, and furthermore the compound annual demand for class one nickel is projected to continue to strengthen throughout the decade. As a result, Murchison is very well positioned to strengthen shareholder value through unlocking the mining-camp scale nickel-copper-cobalt sulphide mineralization at HPM. Discovering responsibly-sourced energy metals from stable jurisdictions – like those we are exploring for at the HPM Project in Quebec and BMK in Saskatchewan – is our focus.Troy BoisjoliPresident and CEO
”The extensive size of the PYC mineralizing system is impressive, demonstrated by the considerable drill intervals we see in the holes released today. The bulk tonnage potential is significant, and PYC further demonstrates the exploration potential of the HPM property – there is nickel mineralization on surface at many of our targets. We have only begun to explore HPM and are eager to continue working the project. Our plans for 2022 will help establish the potential at HPM with a second phase of VTEM survey work commencing this spring followed by prospecting and drill programs - big things are happening and we are excited about the 2022 program.”John ShmyrVice President of Exploration
2021 Fall HPM Drilling Campaign
Today’s assay results demonstrate the depth-continuity of mineralization observed on surface during the summer prospecting program, and the mineralization correlates with a 1.95 km-long electromagnetic anomaly (EM) (see August 16th, 2021 release).
The mineralization consists of half metre- to metre-scale semi-massive to massive sulphides – as well as intermittent sulphide breccias and disseminated sulphides over tens of metres within a dark fine-grained gabbros.
The Company has assays pending from the remaining six holes at the PYC target, which tested 0.55 km of the 1.95 km strike length of the VTEM conductor. The mineralization at the PYC target when paired with results from the adjacent Barre de Fer prospect located 1.5 km to the ESE demonstrates the camp-scale potential of the HPM Project to host high-grade Ni-Cu-Co mineralization at shallow depth.
The results from the fall 2021 drill campaign have demonstrated that Murchison’s exploration methodology is effective in locating Ni-Cu-Co mineralization at the HPM Project. This methodology consists of airborne EM survey work, following-up on the airborne anomalies using a beep mat, then sampling using a backpack drill. Mineralization discovered using the backpack drill provides an inventory of ranked targets that can be tested in 2022.

About HPM Project
The HPM project is located east of the Manicouagan structure, the site of a major 215 Ma impact event. The extensive reservoir at Manicouagan supports five hydro-power plants. The existing Quebec Cartier rail line, located eight kilometres west of the PYC project area, links Labrador City to Port Cartier and Sept Iles, two major iron ore port facilities.
The project is located within the Haut-Plateau de la Manicouagan area. The claims host prospective gabbroic, ultramafic and anorthositic bodies within the Manicouagan metamorphic complex and are associated with significant nickel-copper-cobalt sulphide mineralization first identified by Falconbridge in 1999, and discovered extensive nickel bearing sulphide mineralization at Barre de Fer during drilling in 2001 – 2002. Pure Nickel and Murchison Minerals Ltd.’s predecessor – Manicouagan Minerals – continued drilling in the area until 2008.
The majority of the past drilling at the HPM project targeted the Barre de Fer geophysical conductor and confirmed the presence of nickel-copper-cobalt sulfiphide mineralization over approximately 300 metres strike length to a depth of 280 metres. The mineralization remains open at depth and partially along strike.
After Murchison Minerals Ltd. acquired 100% ownership of the property in 2019, the Company has focused exploration work on the camp-scale potential of the region. Aerial EM surveys completed in the spring of 2021 identified more than 50 anomalous conductors. Prospecting crews were able to traverse 3 of the more than 50 anomalies, and discovered new outcrops of nickel-bearing sulphide mineralization in the process. The prospecting program was followed by an inaugural drill program at the PYC target area – an EM anomaly with a 1.95km strike length. Assay results are expected in Q1 2022. Subsequent to the completion of the drill program at PYC, the Company increased its dominant land position in the Haut- Plateau region from 139 km2 to 576 km2.
Murchison has implemented and is adhering to a strict Quality Assurance/Quality Control program. NQ-size core was drilled, and mineralized intervals were marked by geologists during core description. The marked intervals were sampled using a core saw, one-half is kept as a witness sample at core facility in Saguenay, Quebec and the other assigned a unique number and placed within a plastic bag. The specific gravity of each sample was measured using the mass-in-air / mass-in-water method. Samples were shipped directly to SRC Geoanalytical Labs in Saskatoon, Saskatchewan. The samples were ground and prepared for analysis by the lab using total digestion. Analyzes were performed using ICP-OES for nickel, copper, and cobalt. Every 25th sample sent to the lab was a field duplicate (quarter core), blanks and certified reference material were also submitted approximately every 25th sample.
