STERLING EXPANDS MINERALIZED FOOTPRINT TO 2KM WITH NEAR SURFACE INTERCEPT IN 850M EASTERN STEP OUT

Sterling Metals Corp. has released assay results from initial drilling on a new eastern pad at its Soo copper project near Batchewana Bay, Ontario. The new holes were collared approximately 850 metres east of SC-26-16, the previous eastern limit of the MEPS copper zone.

SC-26-20 returned 206.2 m grading 0.28 per cent copper equivalent from 49.8 m to 256.0 m, including progressively higher-grade intervals of 100.5 m grading 0.40 per cent CuEq, 38.6 m grading 0.65 per cent CuEq and 20.0 m grading 0.98 per cent CuEq. Within the higher-grade portion of the hole, stronger copper is locally associated with massive to semi-massive magnetite containing abundant chalcopyrite and locally covellite. The scale of the stepout, the broad mineralized interval and the early-stage nature of the eastern target create a substantial follow-up opportunity across the intervening and surrounding ground.

Highlights:

• Initial drilling from a new eastern pad, located approximately 850 m east of the current MEPS limit, expands Soo copper's drilled mineralized footprint to approximately two kilometres east-west. Substantial ground between MEPS and the new pad, and around the eastern target, remains untested.
• SC-26-20 intersected 206.2 m grading 0.28 per cent CuEq (0.22 per cent Cu) from 49.8 m to 256.0 m, including 100.5 m grading 0.40 per cent CuEq (0.31 per cent Cu), 38.6 m grading 0.65 per cent CuEq (0.49 per cent Cu) and 20.0 m grading 0.98 per cent CuEq (0.76 per cent Cu). The highest-grade portion of SC-26-20 is locally associated with massive to semi-massive magnetite and bornite.
• All drill holes contain chalcopyrite, bornite, covellite and molybdenum with very low pyrite content suggesting eastern continuity of the same underlying porphyry copper system responsible for the two-kilometre mineralized footprint.
• Register for the coming webinar on Nov. 4 at 12 p.m. ET, where chief executive officer Mathew Wilson will walk through the latest results, what they could mean for a new domestic source of critical copper and the milestones investors should watch in the months ahead.

Mr. Wilson, CEO, commented: "In just 18 months of drilling, the MEPS discovery has demonstrated scale, near-surface bulk tonnage potential [and] the capacity for tremendous grades, and the two-kilometre mineralized footprint suggests this is only going to get better. Such a continuous and robust copper system, located in an extremely well-accessed area capable of year-round exploration and exceptional cost-efficiency, makes Soo copper a unique project. The Soo copper project shows all the signs that it has the potential to deliver the copper that Canada and Ontario needs, at a time when the need has never been greater."

Technical discussion

The three holes reported here were drilled from the same new pad approximately 850 m east of SC-26-16, the current eastern limit of the MEPS copper system. SC-26-19 was drilled west-northwest toward MEPS while SC-26-20 and SC-26-21 were drilled southeast at different dips. This first-pass program tested whether mineralization continued beyond MEPS. Together with previously reported drilling, the new eastern holes expand the drilled mineralized footprint at Soo copper to approximately two km east-west.

SC-26-20 was drilled to a final depth of 512.23 m at a dip of minus 70 degrees and an azimuth of 132 degrees. The hole intersected 206.2 m grading 0.28 per cent CuEq from 49.8 m to 256.0 m. Mineralization strengthens downward, with 100.5 m grading 0.40 per cent CuEq from 155.5 m to 256.0 m, including 38.6 m grading 0.65 per cent CuEq from 186.7 m to 225.3 m and 20.0 m grading 0.98 per cent CuEq from 205.3 m to 225.3 m. The strongest mineralization occurs at approximately 218-metre-to-225-metre depth and is associated with massive to semi-massive magnetite containing abundant chalcopyrite and locally covellite.

Within the magnetite-rich portion of SC-26-20, two adjacent samples between 221.90 m and 223.65 m returned 5.42 per cent and 4.53 per cent CuEq, respectively. The association between stronger copper grades and massive to semi-massive magnetite provides a distinctive feature for follow-up targeting. The eastern drilling also shows alteration and geological characteristics that differ from MEPS, including a relative lack of porphyry observed to date. Sterling plans to compare core-scanning and alteration data from the eastern holes with MEPS to refine vectors toward the strongest parts of the eastern system.

SC-26-19 was drilled to a final depth of 321.0 m at a dip of minus 45 degrees and an azimuth of 280 degrees. The hole returned 62.4 m grading 0.29 per cent CuEq from 202.6 m to 264.9 m, including 31.3 m grading 0.42 per cent CuEq with an average of 566.94 parts per million molybdenum. A shallower interval returned 20.1 m grading 0.20 per cent CuEq from 31.9 m to 52.0 m. The interval from 77.5 m to 114.0 m was not sampled for assay after GeologicAI scanning indicated that this portion of the hole did not contain copper above approximately 0.1 per cent. The bottom part of this hole consistently contains the higher Mo grades encountered in this hole in addition to a narrow altered felsic porphyry dike suggesting the approach of a mineralized stock as was intercepted in the bottom of SC-26-16 located 850 m to the west.

SC-26-21 was drilled to a final depth of 402.0 m at a dip of minus 48 degrees and an azimuth of 132 degrees. It returned 59.3 m grading 0.20 per cent CuEq from 156.0 m to 215.3 m, including 4.1 m grading 0.52 per cent CuEq from 211.2 m to 215.3 m. Collectively, these first three eastern holes materially expand the area of known copper mineralization. With substantial ground still untested, Sterling is focused on defining the geometry, scale and higher-grade portions of this emerging eastern zone and its relationship to the MEPS discovery zone.

Sampling procedures -- quality assurance/quality control

Analytical services were provided by Actlabs, an independent accredited analytical laboratory. Drill core was logged and split with a diamond saw, and half-core samples were securely stored prior to shipment to the laboratory.

Samples were prepared by crushing, splitting and pulverizing before multielement analysis following a near-total four-acid digestion. Selected sample pulps were analyzed for gold by fire assay. The laboratory program included blanks, controls, duplicates and certified reference materials, supplemented by Sterling's systematic insertion of blanks, duplicates and certified reference materials as part of the company's internal QA/QC program.

About the Soo copper project

The Soo copper project sits just 20 minutes off the Trans-Canada Highway, one hour north of Sault Ste. Marie and 20 km from rail and deepwater access. With near-surface copper mineralization, demonstrated scale and grade, and proximity to existing infrastructure, Sterling believes Soo copper has the potential to emerge as a critical Canadian copper project.
