Azimut Announces Initial Mineral Resource Estimate for the Patwon Gold Zone, Elmer Property, James Bay Region, Quebec
LONGUEUIL, Quebec, Nov. 21, 2023 (GLOBE NEWSWIRE) -- Azimut Exploration Inc. (“Azimut” or the “Company”) (TSXV: AZM) (OTCQX: AZMTF) is pleased to announce the results of the initial mineral resource estimate (“MRE”) for the Patwon Gold Zone on its 100% owned Elmer Property in the Eeyou Istchee James Bay region of Quebec:
- Indicated resources: 311,200 ounces in 4.99 million tonnes grading 1.93 g/t Au
- Inferred resources: 513,900 ounces in 8.22 million tonnes grading 1.94 g/t Au
The MRE, prepared according to National Instrument 43-101 (“NI 43-101”), confirms the quality of the gold mineralization in the Patwon Zone and supports additional exploration to further expand the mineral inventory. Two objectives have been defined for the upcoming drilling program, which is scheduled to commence in early 2024:
- Expand the Patwon Gold Zone, which remains open near surface along strike, using shallow drill holes from surface down to a vertical depth of 300 metres; and
- Follow up on significant gold-bearing zones along shear zones directly on strike or subparallel to Patwon. The main drill-ready target zones have a cumulative strike length of 20.5 kilometres.
HIGHLIGHTS (see Figures 1 to 6)
- The initial MRE comprises:
Open-pit mineral resources using a 0.55 g/t Au cut-off:
Indicated: 309,200 ounces (“oz”) in 4.97 million tonnes (“Mt”) grading 1.93 g/t Au
Inferred: 310,700 oz in 4.21 Mt grading 2.29 g/t Au
Bulk underground mineral resources using a 1.05 g/t Au cut-off:
Inferred: 163,700 oz in 3.49 Mt grading 1.46 g/t Au
Selective underground mineral resources using a 1.90 g/t Au cut-off:
Indicated: 2,000 oz in 0.022 Mt grading 2.83 g/t Au
Inferred: 39,500 oz in 0.52 Mt grading 2.36 g/t Au
- As noted above, the MRE considers three potential mining methods for Patwon. The MRE is based on approximately 60,609 metres of diamond drill core in 167 holes drilled by Azimut between November 2019 and March 2023. A complete list of results is available on the following webpage: Elmer Drilling Data.
- 3D modelling of the gold zone indicates that Patwon remains open along strike and at depth. Incremental drilling at shallow depth along strike could add resources to the initial MRE. Patwon is currently defined along a strike length of 600 metres, from surface to a vertical depth of 860 metres (900 m down-dip), with an average estimated true width of 35 metres and a dip of 75° to the north. The open-pit resources are defined from surface to a maximum depth of 376 m. The key geologic features of the zone are described in Table 1 in the press release issued on June 29, 2023.
- A sensitivity analysis indicates low variability of the MRE under various gold price and cut-off grade scenarios, underscoring the robustness of the Patwon Gold Zone.
- Preliminary metallurgical tests indicate non-refractory free-milling gold that is easily recoverable through a combination of gravity circuit and conventional cyanide leaching. Recovery rates reach up to 94%, with gravity recoveries up to 37%. (see press releases of May 4 and November 21, 2021).
- Several target areas outside the Patwon Zone have been tested by 15,554 metres of diamond drill core in 75 holes drilled by Azimut. The results from these programs have been very encouraging (see press release of June 29, 2023). Follow-up drilling is part of the work planned for 2024.

Notes:
- These mineral resources are not mineral reserves as they do not have demonstrated economic viability. The MRE follows current CIM Definition Standards (2014) and CIM MRMR Best Practice Guidelines (2019). A technical report supporting the MRE will be filed within 45 days in accordance with NI 43-101. The results are presented undiluted and are considered to have reasonable prospects for eventual economic extraction (“RPEEE”).
- The independent and qualified persons (“QPs”) for the mineral resource estimate, as defined in NI 43-101, are Martin Perron, P.Eng., Chafana Hamed Sako, P.Geo., and Simon Boudreau, P.Eng., all from InnovExplo Inc. The effective date is November 14, 2023.
- The estimate encompasses six (6) mineralized domains and one (1) dilution zone developed using LeapFrog Geo and interpolated using LeapFrog Edge.
- 1.0-m composites were calculated within the mineralized zones using the grade of the adjacent material when assayed or a value of zero when not assayed. High-grade capping on composites (supported by statistical analysis) was set between 15.0 and 40.0 g/t Au for high-grade envelopes, 0.2 and 12.5 g/t Au for lower-grade envelopes, and 1.0 g/t Au for the dilution envelope.
- The estimate was completed using a sub-block model in Leapfrog Edge, with a parent block size of 4m x 4m x 4m (X,Y,Z) and a sub-block size of 1m x 1m x 1m (X,Y,Z).
- Grade interpolation was obtained by the Inverse Distance Squared (ID2) method using hard boundaries.
- Density values of 2.76 to 2.8 g/cm3 were assigned to all mineralized zones.
- Mineral resources were classified as Indicated and Inferred. Indicated resources are defined with a minimum of three (3) drill holes in areas where the drill spacing is less than 20 m, and Inferred resources with two (2) drill holes in areas where the drill spacing is less than 40 m and there is reasonable geological and grade continuity.
- The MRE is locally pit constrained. The out-pit resources meet the RPEEE requirement by applying constraining volumes to all blocks (combined bulk and selective underground long-hole extraction scenario) using Deswik Mineable Shape Optimizer (DSO).
- The RPEEE requirement is satisfied by having cut-off grades based on reasonable parameters for surface and underground extraction scenarios, minimum widths, and constraining volumes. The estimate is presented for potential underground scenarios (realized in Deswik) over a minimum width of 2 m for blocks 20 to 24 m high by 16 to 20 m long at a cut-off grade of 1.05 g/t Au for the bulk long-hole method (BLH) and 1.90 g/t Au for the selective long-hole method (SLH). Cut-off grades reflect the currently defined geometry and dip of the mineralized envelopes. The potential open-pit component (OP) of the 2023 MRE is locally constrained by an optimized surface in GEOVIA Whittle™ using a rounded cut-off grade of 0.55 g/t Au. The surface cut-off grade was calculated using the following parameters: mining cost = CA$3.55/t; mining overburden cost = CA$2.49/t; processing cost = CA$22.00/t; G&A cost = CA$15.60/t; selling costs = CA$5.00/t; gold price = US$1,800/oz; USD/CAD exchange rate = 1.30; overburden slope angle = 30°; bedrock slope angle = 50°; and mill recovery = 94%. The underground MRE was based on two mining methods, the choice of which depends on the width of the mineralization. The underground cut-off grade was calculated using the following parameters: mining cost = CA$35.00/t (bulk long-hole) to CA$95.00/t (selective long-hole); processing cost = CA$22.00/t; G&A cost = CA$15.60/t; selling costs = CA$5.00/t; price = US$1,800/oz; USD/CAD exchange rate = 1.30; and mill recovery = 94%.
- Cut-off grades should be re-evaluated in light of future prevailing market conditions (metal prices, exchange rates, mining costs etc.).
- The number of metric tons (tonnes) was rounded to the nearest thousand, following the recommendations in NI 43-101. The metal contents are presented in troy ounces (tonnes x grade / 31.10348) rounded to the nearest hundred. Any discrepancies in the totals are due to rounding effects.
- The QPs are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, or marketing issues or any other relevant issue not reported in the Technical Report that could materially affect the Mineral Resources Estimate.

EXPLORATION UPSIDE
Azimut considers the 35-kilometre-long Elmer Property to remain at an early exploration stage with strong gold potential supported by the following salient features:
| 1) | A favourable geological and structural context: | ||
| - | Archean greenstone belt dominated by felsic intrusions, felsic volcanics and gabbroic sills | ||
| - | Extensive shear zones along the belt | ||
| - | Low-grade greenschist metamorphic window over a large part of the property | ||
| - | Close to a major geological subprovince boundary | ||
| 2) | The presence of numerous gold prospects outlining a highly prospective area 12 kilometres long by 3 kilometres wide, containing frequent high-grade gold values often accompanied by a broad and consistent alteration footprint (Ag-Bi-Mo-Pb-S-Te-W); and | ||
| 3) | A low level of exploration maturity with limited follow-up drilling on many of the property’s prospects. | ||
