Murchison Minerals Intersects 277.3 Metres of Nickel-Bearing Sulphide Mineralization at the Syrah Target and Confirms Grades of 5.01% NiEq or 16.25% CuEq at the Lac Paradis Prospect

BURLINGTON, ON / ACCESSWIRE / February 7, 2023 / Murchison Minerals Ltd. ("Murchison" or the "Company") (TSXV:MUR)(OTCQB:MURMF) is pleased to announce assay results from the diamond drillholes completed at the Syrah Target as part of the 2022 Summer Exploration Program on the 100% - owned HPM (Haut-Plateau de la Manicouagan) Project, located in Quebec. At the Syrah Target - which lies approximately 300 m to the northwest of the Barre de Fer (BDF) Zone - Nickel-Copper-Cobalt mineralization has been traced on surface over a 775 m strike length. These drillhole results confirm the presence of extensive disseminated nickel-bearing sulphide mineralization extending to depth. Murchison is confident the disseminated mineralization intersected in its first drill program is a key vectoring tool towards discovery of more massive to semi-massive mineralization within the target area to the south.

Additionally, the Company is pleased to announce backpack drill results from the initial prospecting program confirming the presence high-grade nickel-copper-cobalt on surface at it's 100% owned Lac Paradis Prospect. Lac Paradis Prospect is located approximately 120 km southwest of the HPM Project area and was initially acquired by the Company in January of 2022.

Highlights

• SYR22-001 intersected extensive disseminated Ni-Cu-Co bearing sulphide mineralization over 277.3 m:
  • 277.3 m grading 0.22% NiEq. or 0.70% CuEq. (58.00 to 335.33 m) in SYR22-001
    • Including 30.33 m at 0.33% NiEq. or 1.08% CuEq. (305.00 to 335.33 m)
    • Includes 4.80 m at 0.54% NiEq. or 1.75% CuEq. (323.7 to 328.5 m)
• Mineralization intersected at Syrah confirms the presence of a large magmatic sulphide system but does not explain the conductive geophysical anomaly. The target remains highly prospective to host high-grade nickel-bearing sulphide mineralization
• At the Lac Paradis Prospect, the backpack drill results are highly prospective confirming high-grade Ni-Cu-Co sulphide mineralization:
  • 1.55 m backpack drill core grading 1.43% NiEq. or 4.65% CuEq.
    • Including 0.37m grading 5.01% NiEq. or 16.25% CuEq. (0.00 to 0.37 m)
  • 1.40 m backpack drill core grading 2.11% NiEq. or 6.84% CuEq.
    • Including 0.46 m at 4.06% NiEq. or 13.17% CuEq. (0.40 to 0.86 m)

Murchison Minerals President and CEO Troy Boisjoli comments:

"Today's release is a confirmation of the upside potential of the HPM project. Syrah is just one of the many known nickel-bearing sulphide showings along the 5 km BDF Trend, and adjacent 7 km long PYC Trend. The confirmation that mineralization continues at depth, along with how the geoscience has evolved our understanding of this extensive nickel-bearing sulphide system are positioning the HPM Project as one of the only true newly discovered nickel-sulphide districts globally."

Murchison Minerals Vice-President of Exploration John Shmyr comments:

"We are pleased with the results at Syrah, we feel the results to date are strong evidence of a significant magmatic nickel system being present. We see similar large broad zones of disseminated sulphide adjacent to the high-grade mineralization at Barre de Fer. The 3 holes were drilled to test a strong area in the airborne VTEM data but reprocessing of the previous EM surveys indicate that southern portion of the anomaly as being prospective and this agrees with the higher-grade surface mineralization located there. We are eager to drill this target soon."

2022 Syrah Drill Results

During the Summer 2022 Exploration Program a fence of three diamond drillholes were completed at the Syrah Target. The drillholes were spaced approximately 75 to 125 m apart, testing an area proximal to mineralization intersected in hole HPM-08-14 -completed in 2008, returning grades of 0.18% Ni Eq. (0.12% Ni, 0.09% Cu, 0.02% Co) over 15.62 m. To date, sulphide mineralization at Syrah has consisted of broad disseminated zones of pyrrhotite and chalcopyrite, with lessor amounts of pentlandite, hosted within a gabbronorite. Half-metre intervals of semi-massive sulphide mineralization were intersected in SYR22-001 and SYR22-002. These broad zones of nickel-bearing sulphide mineralization confirm the presence of a magmatic sulphide system, which may have the same source as the high-grade BDF Zone. Future exploration work will be focused on the southern extents of the anomaly. Surface mineralization at Syrah was mapped using a beep mat, with the best prospecting results discovered in the southern most extents of the Syrah target -the best grab sample results returned grades of 0.74% NiEq. (0.58% Ni, 0.24% Cu, 0.05% Co).

Lac Paradis Prospect Results

Murchison conducted an extensive prospecting program on the HPM project during the 2022 summer exploration program. As part of this program, the technical team completed reconnaissance prospecting at its Lac Paradis Prospect, at a previously identified showing. The Lac Paradis Prospect is located at the south end of Lac Manicouagan, approximately 17 km north of the Manic-5 Hydroelectric Dam, and 120 km southwest of the HPM property. The Lac Paradis Prospect was staked by Murchison in January of 2022. Nickel mineralization was discovered by prospecting in 2003 along a forestry road, the mineralization contains grades of 2.9% Cu and 5.26% Ni in grab samples in disseminated to semi-massive sulphide patches in meta-pyroxenite associated with leucogabbro and olivine-bearing ultramafic dyke. Four shallow BQ holes were drilled in 2006 totaling 217.34 m, with no samples collected and no notable mineralization intersected. The lack of exploration paired with the high-grade nature and presence of ultramafic magmatism (Figure 3) make the Lac Paradis highly prospective. Murchison will complete more extensive prospecting in future programs utilizing a beep mat to attempt to locate additional mineralization associated with the ultramafic intrusions.

QA/QC

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 every 10th 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.
