High-grade gold mineralization intersected near surface, 200 metres southwest of the current pit shell, with 73.5 g/t Au over 1.35 metres.
Gold mineralization intersected up to 100 metres northeast of the current mineral resource estimate, with up to 8.0 g/t Au over 1.0 metres.
Results of drilling east of the deposit to fill in larger gaps at 50 m centres include 12.75 g/t Au over 1.7 metres, 12.3 g/t Au over 0.75 metres, 12.0 g/t Au over 0.8 metres, 10.9 g/t Au over 0.6 metres and 10.2 g/t Au over 1.1 metres.
The current drilling program on McKenzie Break is ongoing and another program is planned for 2022.
MONTREAL, Dec. 02, 2021 (GLOBE NEWSWIRE) -- MONARCH MINING CORPORATION (“Monarch” or the “Corporation”) (TSX: GBAR) (OTCQX: GBARF) is pleased to announce significant new assay results from ongoing drilling on the McKenzie Break deposit, located 25 kilometres north of the Corporation’s wholly owned 750 tonne-per-day Beacon mill. These drill results are part of Monarch’s 2021 McKenzie Break exploration program, which consists of a total of 56 holes for approximately 19,000 metres. Earlier results from the program were reported on October 20 (3.93 g/t Au over 5.45 m), June 22 (70.8 g/t Au over 0.4 m) and March 22, 2021 (8.46 g/t Au over 13.8 m). The results for the remaining 18 holes are expected to come in over the next couple of months.
The current exploration program is focused on expanding the size of the McKenzie Break gold deposit and supplementing the recently updated mineral resource estimate (the “2021 MRE”, see press release dated Feb 8, 2021). Based on recent results outside the 2021 MRE envelope, the current program has indeed succeeded in expanding the deposit to the southwest and northeast.
The new assay results presented below are among a total of 91 intersections from 31 drill holes (see Tables 1 and 2). Most of those intersections lie outside the 2021 MRE blocks and wireframes. Monarch continues to test the outer limits of the deposit with holes at 50-metre centres.
Highlights of near-surface results intersected approximately 200 metres southwest of the 2021 MRE include:
MK-21-286: 73.5 g/t Au over 1.35 m, followed by a deeper zone grading 1.38 g/t au over 4.95 m.
MK-21-306: 50 metres south of hole MK-21-286, intersected widespread low-grade mineralization, including 0.92 g/t Au over 17.0 m and a deeper zone grading 0.98 g/t Au over 11.5 m.
MK-21-305: 50 metres north of hole MK-21-286, returned 2.39 g/t Au over 2.0 m, followed by a deeper zone grading 4.5 g/t Au over 0.7 m.
Highlights of grades intersected more than 100 metres northeast of the 2021 MRE include:
MK-21-290: 4.0 g/t Au over 1.0 m, followed by a deeper zone grading 8.0 g/t Au over 1.0 m.
MK-21-294: 50 metres west of hole MK-21-290, returned 4.5 g/t Au over 1.0 m followed by a lower zone of 5.5 g/t Au over 1.0 m.
Highlights of grades intersected east of the resource and including those intersected more than 50 metres from the 2021 MRE include:
MK-21-268: 12.75 g/t Au over 1.7 m.
MK-21-295: 12.0 g/t Au over 0.8 m and 4.29 g/t Au over 2.6 m.
MK-21-297: 10.9 g/t Au over 0.6 m.
MK-21-299: 12.3 g/t Au over 0.75 m.
MK-21-300: 10.2 g/t Au over 1.1 m.

Monarch has now extended the mineralized envelope an additional 200 metres to the southwest (updip) and 100 metres to the east and northeast (downdip). The current mineralized envelope now measures 1,100 metres by 600 metres and has been tested from surface to a maximum vertical depth of 430 metres. The McKenzie Break deposit continues to remain open for expansion and shows good grade and continuity.
“McKenzie Break continues to show great high-grade gold potential,” said Jean-Marc Lacoste, President and Chief Executive Officer of Monarch. “Ongoing drilling continues to push the outer limits of the resource envelope and is generating input for a mineral resource estimate update expected to begin in 2022.”
Monarch will continue exploration drilling on the McKenzie Break property to the end of 2021, on the current drilling pattern, with holes every 50 metres. A new drilling program planned for 2022 will include continued testing of the current outer limits of the resource estimate, drilling of a large target area between the resource pit shell and the recent intercepts 1 km to the south of the pit shell, and drilling of regional exploration targets located approximately 9 kilometres south of the deposit.

About McKenzie Break
Gold mineralization occurs in an elongated diorite unit or lens within a shallow embayment of the Pascalis Batholith. Monarch continues to have drilling success beyond the limits of the recent resource update provided by Geologica and GoldMinds (see Table 3 and press release dated February 8, 2021). The mineralized envelope currently measures 1,100 metres by 600 metres and has been tested down to a vertical depth of 430 metres. The Corporation will continue testing the limits of the defined mineralized envelope as well as other priority targets on the property with its drilling program, of which approximately 17,000 metres have been drilled to date, in 50 holes. Drilling has been ongoing since April 2021, with one or two drill rigs.

Notes:
Mineral resources which are not mineral reserves do not have demonstrated economic viability. An Inferred Mineral Resource has a lower level of confidence than that applying to a Measured and Indicated Mineral Resource and must not be converted to a Mineral Reserve. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, market or other relevant issues. The quantity and grade of reported inferred resources are uncertain in nature and there has not been sufficient work to define these inferred resources as indicated or measured resources.
The database used for this mineral estimate includes drill results obtained from historical records and up to the recent 2018-2020 drill program.
Mineral resources are reported at a cut-off grade of 0.50 g/t Au for the pit-constrained and underground mineral resources are reported at a cut-off grade of 2.38 g/t Au within reasonably mineable volumes.
These cut-offs were calculated at a gold price of C$1,980 ounce.
The pit-constrained resources were based on the following parameters: mining cost $3.5/t, processing, transportation + G&A costs $27/t, Au recovery 95%, pit slopes 15 degrees for overburden and 50 degrees for rock.
The underground reasonably mineable volumes were based on the following parameters: mining cost $98/t, processing, transportation + G&A costs $27/t, Au recovery 95%, dilution of 15% at 0 g/t Au with a minimum stope dimension of 10m x 10m x 5m.
The geological interpretation of the deposits was based on lithologies and the typical mineralized interval mainly composed by diorite hosted shear zones.
The mineral resource presented here was estimated with a block size of 5m x 5m x 5m for the pit-constrained and for underground.
The blocks were interpolated from equal length composites calculated from the mineralized intervals. Prior to compositing, high-grade gold assays were capped to 60 g/t Au applied on 0.6-metre composites.
The mineral estimation was completed using the inverse distance squared methodology utilizing two passes. For each pass, search ellipsoids followed the geological interpretation trends were used.
Tonnage estimates are based on rock specific gravity of 2.77 tonnes per cubic metre for all the zones. Results are presented undiluted and in situ.
Estimates use metric units (metres, tonnes and g/t). Metal contents are presented in troy ounces (metric tonne x grade / 31.10348).
This mineral resource estimate is dated February 1, 2021, and the effective date for the drillhole database used to produce this updated mineral resource estimate is September 28, 2020.
No economic evaluation of the resources has been produced.
The resource estimate was prepared by Merouane Rachidi, P.Geo., Ph.D., and Claude Duplessis, P.Eng., of GoldMinds Geoservices Inc., both qualified persons under National Instrument 43-101.
Sampling consists of sawing the NQ-size core into equal halves along its main axis and shipping one of the halves to AGAT Laboratories in Mississauga, Ontario, for assaying. The samples are crushed, pulverized and assayed by fire assay, with atomic absorption finish. Results exceeding 3.0 g/t Au are re-assayed using the gravity method, and samples containing visible gold grains are assayed using the metallic screen method. Monarch uses a comprehensive QA/QC protocol, including the insertion of standards and blanks.
The technical and scientific content of this press release has been reviewed and approved by Louis Martin, P.Geo., the Corporation’s qualified person under National Instrument 43-101.
