Heritage Mining Ltd. Reports Preliminary Results from Drayton-Black Lake Project
Heritage Mining Ltd. reported the preliminary results from its ongoing exploration program at the Company's flagship Drayton-Black Lake project and provide an update on upcoming exploration activities. The Drayton-Black Lake Project is located in northwestern Ontario, approximately 20 km northeast of Sioux Lookout, Ontario, totaling approximately 15,257 Ha and lying near the northern margin of the Wabigoon Sub province within the Abrams Minnitaki Lake ("AML") Greenstone Belt along strike of and contiguous with Treasury Metals Inc.'s Goliath Gold-Silver Complex. The Company initiated its inaugural field program at the Drayton-Black Lake Project after a systematic review of archived mineral exploration data for the Drayton-Black Lake Project area. The new Heritage dataset, which includes surface exploration and diamond drilling data for over twenty base and precious metal mineral occurrences and prospects, was compiled from public data and virtual data rooms of several property vendors. Company identified high potential gold, gold-silver and gold-copper areas (incl. targets/prospects) for follow-up work. These include the Moretti, Alcona, Split Lake, Alkenore, McCombe, Drayton and Forster areas. A Phase I field program has been completed for several areas. The program, which began in July with three field crews, focused on priority targets/prospects within the initial exploration areas and consists of confirmation mapping and sampling along with detailed regional prospecting. New logging roads and new compilation data provide good spatial control and efficient access to throughout the property. All samples in Phase I of the 2022 field program were analyzed for gold and copper only. Project and Exploration Highlights (Area/Target/Prospect) large land package in a prospective, under-explored greenstone belt along strike of Treasury Metals Inc.'s Goliath Au-Ag Complex: New logging roads provide unprecedented access throughout the Drayton Black-Lake Project. Regional prospecting has identified new mineralized prospects close to new logging roads. Secured additional land position (Split Lake Extension), wholly owned, totaling 1,036Ha. Completed a 1,574 l-km airborne geophysical survey (Mag /EM) over the Property: High resolution (100m line spacing) helicopter magnetometer and electromagnetic (ProspecTEM) survey data provided new detailed map control regional structural interpretations. Detailed magnetic map patterns (identified in the magnetic derivative data sets based on interpreted folds, flexures and fault patterns) highlight the structural complexity of the property and provide context for first pass target evaluation and the newly identified prospects. EM anomalies will be field checked into the fall as certain styles of mineralization in AML greenstone belt are associated with semi-massive sulphides. Several targets/prospects in the Drayton-Black Lake Project have a precious metal - base metal association, which has been confirm in the current field program. Several styles of high-grade mineralization have been noted based on field observations and early assay results from the Phase I field program (confirmation mapping and sampling of priority targets): Alcona Area (includes Alcona Mine, Alcona West, New Millennium Targets and other prospects): Confirmation sampling and prospecting on exposed bedrock at the Alcona Mine prospect (vein 1, vein 2, vein 3 and central vein) and the Alcona Mine West ("AMW") prospect identified extensive quartz-carbonate vein arrays in strongly sheared (E-W trending) metavolcanic rocks; locallyassociated with extensive sulphide mineralization (vein and altered wall rock) consisting of galena, pyrite, chalcopyrite and minor pyrrhotite: Sampling of central vein 3 returned values of 58.1 g/t, 33.5 g/t and 0.006 g/t Au. Sampling of veins 2 and 3 returned results of 0.057 g/t, 0.128 g/t and 2.3 g/t Au. Confirmation sampling and prospecting on exposed bedrock in Trench 2 and Trench 5 (historic trenching) at Alcona New Millennium prospect identified extensive shear-hosted mineralized quartz-carbonate +/- sulphide veins: Sampling of individual veins in Trench 5 prospect yielded results of 0.013 g/t, 3.75 g/t, 46.5 g/t 32.6 g/t Au. Sampling of individual veins in Trench 2 prospect yielded results ranging from below detection to one sample of 4.21 g/t Au. Confirmation sampling and prospecting at AM-W identified a more complex vein array in this area comprised of variable trending quartz veins (5-75 cm wide) in a folded and sheared metavolcanic rock package: Sampling of individual veins returned values of 1.345 g/t, 12.45 g/t, 6.09 g/t and 24.6 g/t Au from the Pond Target (Powerline prospect). Moretti Area (includes Moretti ("Main Trench"), Rosnel, Bellekeno, Clamshell Lake and Black Lake Targets and other prospects) Prospecting and chip sampling results included: Bonanza Prospect: Grab samples from o/c returned grades up to 0.949 g/t Au. New "Corner" Prospect identified adjacent to logging road: 20 m wide zone of sheared altered metavolcanic rocks. Narrow stockwork veins throughout (Py, Cpy +/- Aspy). Two samples returned values of 0.137 g/t and 0.136 g/t Au. Results pending for other prospects. Assay results are pending from several of the other exploration areas, targets and prospect. The Company's field crew continues to conduct prospecting, mapping and sampling on priority target areas. Upcoming field work will focus on more detailed systematic mapping and sampling (e.g., channel sampling of exposed mineralized vein systems) of priority areas (Moretti, Alcona Mine, Alcona West and Alcona New Millennium). Detailed mapping will focus on i) vein classification, orientation and mineralization, ii) wall rock identification, alteration and mineralization,ii) gold (silver) deportment and iv) expanded multi-element analysis to determine exploration vectors and prioritize current targets for the planned drill program. Additional prospecting will be completed around i) priority areas, ii) historic targets not yet investigated and iii) new prospects identified in Jul-Aug field work. Upcoming desktop work will include i) continued compilation of historic data, ii) processing enhancement and interpretation of new geophysical (Mag+EM) data, iii) review and analysis of historic till sample data (i.e. 2018-2020 ODM till - Au grain studies) and iv) drill target preparation (e.g., 3D compilation and interpretation).
