Minto Metals Reports Multiple High-Grade Copper Intersections From Follow-up Drilling at Minto North Including 1.91% Copper Over 34.59 Metres

WHITEHORSE, YT, Feb. 2, 2023 /CNW/ – Minto Metals Corp. (“Minto” or the “Company”) is pleased to report the progress from its 2022 exploration drilling program at the Minto Mine located within the Selkirk First Nation’s Territory in central Yukon, Canada.

The Company reports updated drill results from its recently completed 2022 exploration drilling program at Minto North. Drill hole 22EXP045 cut 1.91% Copper (“Cu”) over 34.59 metres (“m”) including 4.80% Cu over 10.10 m drill width from 194.19 m downhole in follow-up, step-out drilling from drill hole 21EXP003 (see press release date March 15, 2022) that cut 1.58% Cu over 28 metres. These and other  results represent mineralization west of the current NI 43-101 resource at Minto North (see NI 43-101 Preliminary Economic Assessment Technical Report, Minto, Yukon, Canada with an effective date of March 31, 2021).

Additional Highlights (Figure 1):

Hole 22EXP044

• 1.71% Cu over 20.14 m including 2.43% Cu over 11.14 m from 200 m downhole;

Hole 22EXP047

• 0.45% Cu over 49.38 m including 1.18% Cu over 5.63 m from 223.74 m downhole; and 

Hole 22EXP048

• 0.28% Cu over 60.46 m including 1.40% Cu over 1.99 m from 199.03 m downhole.

David Benson, Vice-President Exploration commented, “We are pleased and encouraged by the results from follow-up, step-out drilling at Minto North. This drilling has confirmed the existence of a consistent, robust mineralized system west of the historical Minto North Pit. These results give us full confidence to proceed with further delineation drilling at Minto North and the expectation to increase the Company’s mineral inventory in 2023.”

“We have a five-year plan with the objective to increase our mineral resource base. The ultimate goal is to achieve a 12 to 15 year life of mine at Minto. A 26,000-hectare underexplored land package in the historic Minto copper belt should allow us to develop new advanced exploration projects,” commented Chris Stewart, President & CEO. “I am looking forward to the planned 84 hole, 30,000 metre drilling program which follows up on 2021-2022 discoveries. We will regularly update the market as results return from the lab.”  

Assay and Drillhole Analysis

As of December 31st, 2022 Minto has completed 53 holes for 28,438 metres (Figure 1). Previous results for 2022 were reported in the press release dated April 28, 2022 and October 20, 2022. Drilling was conducted under the conditions and authorizations of Quartz Mining Land Use Permit# LQ00565 issued by the Department of Energy Mines and Resources, Yukon Government (Figure 2). Results released today are from five drill holes totalling 2,261 m (see Table 1 for Drill hole information and Table 2 for Assay results).

Results reported today (Figures 3&4) were drilled as 50-metre step-outs from mineralization intersected in hole 21EXP003 (see March 15, 2022 release) and 22EXP042 (see October 20, 2022 release) that successfully intersected 28 m @ 1.58% Cu including 9 m @ 3.50% Cu and 20 m @ 2.20% Cu including 5.05% Cu over 3.65 m, respectively. Hole 22EXP044 was drilled 50 m north of 21EXP003 returned 20.14 m @ 1.71% Cu including 11.14 m @ 2.43% Cu.  Hole 22EXP045 was drilled approximately 50 m southeast of 21EXP003 and returned 34.59 m @ 1.91% Cu including 10.10 m @ 4.80% Cu.   Hole 22EXP046 was drilled approximately 50 m west of 22EXP042 but failed to return significant quantities of Cu mineralization.  Holes 22EXP047 and 22EXP048 were drilled 100 m and 150 m east of 22EXP045, respectively and returned thick, lower-grade Cu mineralization (49.38 m @ 0.45% Cu and 60.46 m @ 0.45% Cu, respectively), vertically 50 m deeper than mineralization encountered in holes 21EXP003, 22EXP042, -44 and -45. 

Mineralized host rocks (quartzo-feldspathic migmatite) and sulphide speciation (bornite and chalcopyrite) are consistent in all holes reported with a direct correlation between sulphide content and Cu grade. The results reported herein are well correlated with a moderate-strong chargeability anomaly (Figure 3) detected during a 2010 Orion 3D DC-IP survey performed by Quantec Geoscience on the Mine Property.   Current interpretation suggests a western, fault-displaced downwards extension of the Minto North orebodies.  The chargeability anomaly associated with mineralization reported measures approximately 350 metres by 150 metres. 

Outlook

The Company completed 28,438 m from 53 drill holes of Exploration drilling in 2022. Currently, the Company is awaiting the QA/QC reports and final assay results from the assay lab for portions of 28 additional holes (4,832 samples submitted).  These are expected and will be reported later in Q1 2023. Of particular interest are results at Minto East drilled during September – October. In Q1 2023, the Company expects a preliminary report from ALS Goldspot Discoveries that utilized the historical geoscience and engineering database and newly acquired geophysics from 2022. This report will include machine learning derived prospectivity heat-maps highlighting areas with a high probability for mineralization, prioritized drill targets and an updated 3D geological model. The Company is planning an aggressive resource growth and discovery drill program for 2023 and will provide guidance following Board approval in the coming weeks.
