MONARCH MINING CORPORATION (TSX: GBAR) (OTCMKTS: GBARF) is pleased to announce the first set of results from its 2020-2021 exploration diamond drilling program on its wholly-owned McKenzie Break project, located 25 kilometres north of Val-d’Or, Québec. The results include several significant intersections as Monarch continues to expand the high-grade section of the recently estimated resource towards the south, east and west.
“We are very pleased that we have been able to expand the mineralized envelope beyond the limits of the previous resource estimate with wide intersections from holes like MK-20-259, and that there is continuity between drill holes, even with 50-metre step-outs,” said Jean-Marc Lacoste, President and Chief Executive Officer of Monarch. “We are continuing to follow and expand this high-grade section of the resource estimate by drilling, and will also be testing similar features elsewhere on the newly-expanded property.”
Phase 1 diamond drilling was carried out on 50-metre step-out holes, with 5,912 metres drilled. Assay results are available for 6 of the 12 holes drilled. The most significant result includes 8.46 g/t Au over 13.8 metres from hole MK-20-259, drilled 50 metres south of hole MK-20-255, which had returned an assay of 13.95 g/t Au over 14.35 metres (see press release dated July 23, 2020). Strong results were also obtained 50 metres west of hole MK-20-255, with 19.5 g/t Au over 1.0 metre and 7.83 g/t Au over 1.0 metre in hole MK-20-257. Other significant results are shown on figure 1 and in table 1, below.

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 Corporation will continue drill testing the limits of the mineralized envelope as well as other priority targets on the property, including targets on the newly-staked claims to the south (see press release dated March 8, 2021), with its 8,700-metre Phase 2 drilling program. Drilling is expected to resume in April or May following the spring break-up.
Table 3: Combined resources (in-pit and underground) by category for the McKenzie Break deposit at the selected cut-off grades
|Area (cut-off grade)||Indicated resource||Inferred resource|
|Pit-constrained (0.50 g/t Au)||1,441,377||1.80||83,305||2,243,562||1.44||104,038|
|Underground (2.38 g/t Au)||387,720||5.03||62,677||1,083,503||4.21||146,555|
|1||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.
|2||The database used for this mineral estimate includes drill results obtained from historical records and up to the
recent 2018-2020 drill program.
|3||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.
|4||These cut-offs were calculated at a gold price of C$1,980 ounce.|
|5||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.
|6||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.
|7||The geological interpretation of the deposits was based on lithologies and the typical mineralized interval mainly
composed by diorite hosted shear zones.
|8||The mineral resource presented here was estimated with a block size of 5m X 5m X 5m for the pit-constrained and
|9||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.
|10||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.
|11||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.
|12||Estimates use metric units (metres, tonnes and g/t). Metal contents are presented in troy ounces (metric tonne x
grade / 31.10348).
|13||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.
|14||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 in accordance with National Instrument 43-101 standards.
Sampling consists of sawing the NQ-size core into equal halves along its main axis and shipping one of the halves to the 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, blanks and duplicates.
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.
