First Mining Advances Exploration and Identifies New Targets at the Birch-Uchi Greenstone Belt Project

21.06.2023  |  CNW

VANCOUVER, June 21, 2023 - First Mining Gold Corp. ("First Mining" or the "Company") (TSX: FF) (OTCQX: FFMGF) (FRANKFURT: FMG) is pleased to report exploration results from the Swain and Sol d'Or properties in the Birch-Uchi Greenstone Belt Project ("BUGB Project" or the "Project") located in northwestern Ontario, Canada, near the Company's Springpole Gold Project (the "Springpole Project"). Results from field and drilling programs on these two properties have identified new gold mineralization in favourable geologic settings with a potential for unlocking new discoveries. Work completed in 2022 and work planned for 2023 include components of soil geochemistry, prospecting and mapping, airborne geophysics, and diamond drilling programs.

Highlights of the Exploration Advancements:

  • Identification of key exploration elements in the Grace Deformation Zone over a structural strike length of 6.5 km
  • Discovery of a new gold-in-soil anomaly, including a gold assay of 724 ppb Au, with open opportunity for expansion and infill
  • Return of rock grab samples from the Sol d'Or property, including a high-grade sample of 34.7 g/t Au, confirming potential for a high-grade host environment, and additional samples from the Swain property, including one at 9.3 g/t Au
  • Completion of a 150-line km airborne geophysical survey with advanced processing and modelling supporting forward targeting
  • Identification of six discrete electromagnetic conductive plate models from geophysical modelling favourable for further targeting and resolution advancement
  • Drilling of five priority holes at the Swain property validating a geologic setting of favourable host rocks including notable alteration and mineralization, and including drill intersects of up to 0.64 g/t Au over 5.6 m, and 0.34 g/t Au over 14.9 m

"We continue to be encouraged by the results of our initial exploration phases," stated Dan Wilton, CEO of First Mining. "Building key datasets and evaluating regional host settings in our consolidated district has supported the growth of an important prospectivity pipeline which includes over 80 current targets. The additional targets and potential mineral discovery in our district-scale Birch-Uchi land package provides tremendous upside to our already robust Springpole Project."

Swain - Sol d'Or Targeting

The Swain and Sol d'Or property areas are located approximately 7 km southwest of First Mining's western-most property boundary at the Springpole Project. Exploration targeting is focused along the northwest-southeast striking Grace Deformation Zone ("GDZ"), and the north-south striking Uchi Deformation Zone ("UDZ"), targeting iron carbonate alteration assemblages, and anomalous arsenic and copper values generated from recent field exercises are planned for immediate follow up. The 2022 field campaign by First Mining returned a high gold-in-soil assay of 724 ppb which is associated with mapped shearing and quartz veining within 300 m of the GDZ, an area that has historically produced numerous exploration targets within the Birch-Uchi Greenstone belt, including the historic Sol d'Or mine operated in the 1930's. Prospecting by First Mining in the vicinity of the historic mine returned grab samples with anomalous gold, including one sample at 34.7 g/t Au, further supporting the targeted areas' gold endowment. Mineralization is associated with increased silica and carbonate-altered mafic to intermediate volcanic units and banded iron formations that are host to brecciated and discrete quartz veining, and sulphides. The dominant sulphide mineralization is fine grained, disseminated pyrite and arsenopyrite, averaging an abundance of 1-5%. Most mineralization found across the property is associated with, or found within, the GDZ.

2022 Swain Diamond Drilling

The 2022 Swain diamond drilling campaign comprised 5 drill holes totalling 1,557 metres and was completed as scout-level drill testing along and proximal to the GDZ, in areas prospective for gold mineralization based on geology, grab sampling, geophysics, and structural architecture (see Figure 1). Recent and historical field work identifies grab samples at Swain that returned gold grades of 2.93 g/t Au and 1.59g /t Au, indicative of notable gold endowment with an opportunity to advance and vector within a mineralization system over a meaningful strike length. Mineralization potential has been modelled in 3D with a focus on outward growth and vectoring to areas of higher grade and width (see Figure 2). Select assay results from the Swain drill program are reported below in Table 1, and drill locations are provided in Table 2.

The exploration drilling campaign carried out on the Swain property has been successful in advancing base datasets and target vectoring with exploration validation through the identification of favourable host rock lithologies over zones of meaningful width with increased alteration, veining and mineralization. Results have delineated an area of interest over one kilometre of strike length coincident with the influence of the GDZ structure, which includes drill intercepts of 0.64 g/t Au over 5.6 m, and 0.34 g/t Au over 14.9 m (hole SWL22-001). Initial work has identified important indicators that support further vectoring down strike of the GDZ where additional target work-ups will focus on anomalous soil geochemical values (including 724 ppb Au) at the Hogwarts target and rock grab sample values including 34.7 g/t Au at the Sol d'Or target.

2022 Exploration Field Campaign

Soil Survey Program

A soil survey was designed across the properties to infill any soil sampling gaps from historical data across the GDZ and UDZ. A soil grid targeting the GDZ was designed at 300 m line spacing and 100 m station spacing, and a soil grid targeting the UDZ was designed at 200 m line and station spacing. A total of 159 soil samples were collected across the Swain property. This soil survey was successful in delineating new high priority targets for additional follow-up work and testing. This is highlighted by the 724 ppb Au soil sample which was collected at the newly found Hogwarts target. Infill soil sampling and mapping programs have been designed for follow up in 2023. This survey was also successful in further enhancing the understanding of structures across the property from elevated gold pathfinder elements found along the GDZ and UDZ. A total of 26 soil samples reported below detection limits of 5 ppb Au.

Mapping and Prospecting Program

A total of 129 grab samples were collected during the 2022 field campaign across the properties. Highlights from the grab sample results include gold values of 34.7 g/t, 9.3 g/t, 2.9 g/t, and 1.6 g/t (see Table 3). Each highlighted sample was taken from a different target across the properties, demonstrating the potential gold endowment across multiple structures along strike.

  • Bullseye Target - sheared mineralized mafic volcanics with chalcopyrite and pyrite grab sample towards the southeast portion of the SDZ returning 9.3 g/t Au; the mineralized structure was mapped in the 2022 field campaigns and strikes continuously for 200 m towards the northeast.
  • Snake Target - samples returned gold values including 1.6 g/t and 34.7 g/t, which were collected from sulphide mineralized quartz veining proximal to the historic Sol d'Or areas of development
  • Mystical Target - shear-hosted intermediate volcanics returned 2.9 g/t Au in a mapped mineralized structure along the GDZ

2022 Airborne Geophysics Campaign

In partnership with SkyTEM, a total of 150-line km of airborne magnetics and electromagnetics ("EM") surveying was completed across the Swain & Sol d'Or properties. The survey was successful in confirmation and refinement of major structures and lithologies as well as identifying new key focal points of interest. The magnetics survey well supported high resolution delineation of the GDZ and UDZ structures, and further identifies key stratigraphic units of iron formation and ultramafic intrusive bodies. These units were then confirmed and supported in interpretation with mapping and soil geochemical data collected in 2022. Additional processing work with Mira Geosciences identified six key EM conductive plates as favourable follow-up targets for advancement in 2023. The EM conductor modelling is highlighted by two plates modelled within the Hogwarts target area. These EM targets will be further enhanced with increased mapping and soil geochemical resolution, followed by a detailed 3D geological model and drill targeting program.

Priority Swain Targets

In 2021, First Mining commenced field campaigns targeting initial field validation and assessment of historical showings. Two of the historical showings returned elevated gold; Swain Lake North, which is characterized as foliation parallel, quartz vein-hosted mineralization, returned 6.6 g/t Au; and Hodgson, characterized as quartz vein and felsic volcanic host units, returned samples with elevated Au over a 30 m long exposure. Multi-element assay results indicate a strong association between gold and arsenic anomalies at the Hodgson target as well as the Bobarris West target, a signature that has been identified further along the GDZ.

The Mystical target is hosted within a sheared intermediate volcanic unit with notable chalcopyrite mineralization, returning a 2.9 g/t Au grab sample with results aligned to prospectivity elements of the exploration model. Additional resolution of the area has been further established in drilling of hole SWL22-002 specifically testing the target further at depth.

The Hogwarts target was discovered through a significant gold-arsenic soil anomaly returned from the 2022 field campaign and was further prioritized through the 2022 airborne geophysics survey and modelling. This is a priority and prospective target for the 2023 field season, with infill mapping and soil sampling further planned to expand the geological potential and scalability of this target while understanding the regional association with known prospective targets like the Sol d'Or mine trend.

The Snake target was discovered through historic Sol d'Or mine development review, which demonstrated the potential for increased gold grades within areas of the favourable targets trend. The 2023 field season will focus on advancing the structural controls of the vein system along the Sol d'Or trend, attempting to unlock the understanding of higher-grade settings.

2023 Swain Target Outlook

For 2023, field campaigns on the Swain and Sol d'Or property areas will focus on follow-up and infill sampling, with additional detailed mapping to be focused on deformation zones and projections for the extension of alteration halos, structure and mineralization. Findings will further support integrated exploration models followed by proposed drilling campaigns in the fall of 2023.

Birch-Uchi Greenstone Belt Project

The Birch-Uchi Greenstone Belt Project represents regional scale exploration opportunities that have been consolidated by First Mining surrounding the Springpole Project. This land tenure coupled with the Springpole Project, also located in the Birch-Uchi Greenstone Belt, consists of >70,000 hectares and presents a strong opportunity for new discoveries in an area that is historically underexplored and has only seen a fraction of the exploration work that has been done in the neighbouring Red Lake and Pickle Lake greenstone belts that have been subject to earlier consolidation and discovery cycles.

First Mining has initiated district-scale screening of the Birch-Uchi Project area through a multi-phase commitment to explore and enhance mineral potential within the region.

Analytical Laboratory and QA/QC Procedures

All sampling completed by First Mining within its exploration programs is subject to a Company standard of internal quality control and quality assurance (QA/QC) programs which include the insertion of certified reference materials, blank materials and a level of duplicate analysis. Samples from the 2022 exploration programs were sent to Activation Laboratories located in Thunder Bay, Ontario where they were processed for gold analysis by 50 gram fire assay with an atomic absorption finish, and multi-element analysis (including silver) by inductively coupled plasma (ICP) method with an aqua regia digest for soil samples or four acid digest for core and grab samples. Activation Laboratories systems conform to requirements of ISO/IEC Standard 17025 guidelines and meet assay requirements outlined for NI 43-101.
