Heritage Mining's Sampling Program Reports Highest Gold Assay Ever at the Drayton-Black Lake Project, 2,330g/t Gold

Channel Sampling Program Confirms Multiple High-Grade Gold-Silver Vein System

VANCOUVER, Nov. 29, 2022 - Heritage Mining Ltd. (CSE:HML) ("Heritage" or the "Company") is pleased to announce the results from its recent channel sampling program that evaluated fourteen prospects over five targets in the Alcona and Moretti areas (Table 1) located in the northeastern half of the Company's 15,257 Ha Drayton-Black Lake Project ("DBL"). DBL is located approximately 20km northeast of Sioux Lookout, Ontario (Fig. 1) and covers 30 km of the Central Volcanic and Southern Sedimentary domains within the Eagle-Wabigoon-Manitou ("EWM") Greenstone Belt, which also hosts Treasury Metals Inc.'s (TSX: TML) Goliath Gold-Silver Complex immediately to the southwest.

Channel Sampling Highlights

• Sampling program evaluated fourteen prospects in the Alcona and Moretti areas

• All channels reported anomalous gold silver and base metal mineralization, significant results include:

Alcona-New Millennium (Figure 1)

• T7 Area - 11.2g/t Au and 51.4g/t Ag over 1.0m

• T9 Area - 5.31g/t Au and 25.0g/t Ag over 0.5m

• Quartz vein subcrop material discovered near to T9 shows visible gold and assayed 2,330g/t Au

Moretti-Main (Figure 2)

• North Vein Prospect - 7.85g/t Au over 2.0m; incl. 19.2g/t Au and 72.8g/t Ag over 0.8m

• channel was done near to where a rock chip grab sample assayed 208g/t Au (see press release November 04, 2022)

Alcona-Main (Figure 3)

• Central Vein Set - 2.72g/t Au over 5.1m; incl. 9.41g/t Au and 25.7g/t Ag over 0.8m

• Central Vein Set - 21.9g/t Au and 121g/t Ag over 1.0m

• North Vein Set - 7.85g/t Au over 2.0m; incl. 19.2g/t Au and 72.8g/t Ag over 0.8m

• Alcona Pond - 4.94g/t Au over 4.0m; incl. 15.75g/t Au and 45.1g/t Ag over 1.0m

Peter Schloo, CEO of Heritage Mining commented, "Our first pass channel sampling results have exceeded our expectations, confirming multiple high-grade Au-Ag mineralized vein systems at surface at Alcona, New Millennium and Moretti, similar to Treasury Metals' Goliath gold project. These initial results have provided Heritage with valuable information on the style and tenor of gold and base metal mineralization at DBL, as we plan a more systematic field program for the winter months and into the 2023 exploration season. The team collected a sample of quartz vein subcrop near T9 that reported a whopping 2,330g/t gold, this is the highest reported gold assay at DBL. It is our interpretation that gold, silver, and polymetallic mineralized quartz veins and stockwork zones extend along strike and with depth, and that our ongoing regional evaluation program will continue to identify new veins across this highly under-explored land package. The 2022 field team has done excellent work and our boots on the ground strategy continues to pay off as we further develop the Drayton-Black Lake Project."

Summary:

Phase 1 channel sample results confirm widespread Au-Ag mineralization hosted in deformation zones ranging from discrete 3-5m wide shear structures (New Millennium) to broad (> 200m) composite deformation zones (Alcona Main Area). Channel results along with grab samples confirm the presence of extensive, structurally controlled and locally high-grade Au-Ag mineral systems.

Mineralization is typically associated with several styles of quartz-carbonate (+/- sulphide) veins ranging in thickness from less than 1.0cm to greater than 50cm wide. Vein orientations vary locally but in general reflect related and consistent structural settings at the prospect and target levels. Geophysical data indicates subtle folding patterns in magnetostratigraphy (e.g., mafic / felsic volcanic units) at both Alcona Main and New Millennium area, in addition to complex regional shear patterns throughout DBL. In several instances, veins and vein arrays are consistent with interpreted axial-parallel orientation and displacement. Many vein array orientations are also consistent with regional-scale structural elements that have not been previously recognized. This provides new context to historic results including more recent (e.g., 2018-2021) till geochemistry completed by previous operators.

Multi-element data from the Alcona Area suggest a strong positive relationship between Au-Ag-Te along with positive correlations between Au and several other potential pathfinder elements. Notably, mineralization at Moretti-Main displays lower Ag:Au ratios suggesting multiple mineralization styles may occur in the northeastern half of the Drayton-Black Lake property. This is similar to Treasury Metals' Goliath gold project (i.e. Goliath-Goldlund-Miller deposits) located 25-65 km to the southwest in the EWM Greenstone Belt.

The Company is currently compiling and interpreting mapping and sampling data from the 2022 field program along with processing and interpretation of its newly acquired regional airborne Mag/EM survey data. In conjunction with data from previous operators, staff are now preparing a follow-up program for a planned 2023 drill campaign.

Alcona-New Millennium

At least two mineralized deformation corridors consisting of multiple discrete zones of deformed volcanic rocks and shear parallel quartz veins.

• Additional prospecting around historic trenches recovered a sample of mineralized quartz vein float with visible gold that returned 2,330g/t (D909175)

• Heritage staff were able to expose and sample a small portion of in situ quartz vein and this sample (D909173) returned 18.9g/t Au

Nine (9) channels were completed over the T1, T7 and T9 prospects comprising an area of 500m by 200m. There are two distinct structural trends identified at New Millennium: oriented N-S (T1) and E-W (T7 and T9).

• T9 was assessed over 40m of strike with three (3) channels. Anomalous gold mineralization was encountered in all channels. Highlights include (total length):

  • CH-22-18 (1.5m) - 0.81g/t Au over 1.5m; incl. 1.19g/t Au and 9.06g/t Ag over 0.5m

  • CH-22-17 (3.0m) - 4.69g/t Au and 23.4g/t Ag over 0.5m

  • CH-22-16 (4.2m) - 5.31g/t Au and 25.0g/t Ag over 0.5m

• T7 was assessed over 10m with three (3) channels. Anomalous gold mineralization was encountered in all channels. Highlights include (total length):

  • CH-22-11 (3.0m) - 11.2g/t Au over and 51.4g/t Ag over 1.0m

• T1 was assessed over 50m strike with three (3) channels. Anomalous gold mineralization was encountered in channel CH-22-15 (0.229g/t Au and 1.15g/t Ag over 1.0m).

• Field staff also uncovered a large, previously unsampled, outcrop in the T7 prospect area with extensive veining and alteration. Systematic chip sampling across 5m (N=6) returned anomalous gold values up to 1.3g/t Au.

Moretti

Mineralized deformation corridor over 2,500m of strike 500m wide consisting of discrete zones of deformed volcanic rocks and shear parallel quartz veins ranging from cm to metre scale.

At Moretti-Main, six (6) channels were completed over the north and south vein prospects comprising an area of 150m by 130m. Both steep, shear-parallel veins and shallow discordant vein sets were evaluated.

• At the north vein prospect, a large, well exposed shallow-dipping discordant (to the NE-trending Moretti shear) vein was channeled along strike to assess the bulk gold tenor of that vein and confirm historical sample results. Highlights include (total length):

  • CH-22-40 (10.0m) - 7.12g/t Au over 10m; incl. 51.5g/t Au and 1.38g/t Ag over 1.0m.

    • Including internal dilution with no cutoff applied

  • The results compare well with historical sampling.

  • High-grade gold samples typically exhibit low Ag/Au ratios, in contrast to those from the Alcona area.

• At the south vein prospect, two shear-parallel veins were channeled, and both returned positive gold values. Highlights include (total length):

  • CH-22-30 (1.5m) - 1.23g/t Au over 1.5m

  • CH-22-31 (3.0m) - 1.58g/t Au over 1.0m

At Moretti-Black Lake, fifteen (15) channels were completed on multiple new and historical prospects.

• Au values ranged from below detection to trace with a positive correlation between Au and Ag noted even in the lower tenor results.

• Several of the channel sites were selected to test local deformation zones with well-developed ductile shear fabrics and moderate to intense carbonate alteration. Quartz veins were typically mm-scale with an Fe-carbonate association.

Many vein array orientations are also consistent with regional-scale structural elements that have not been previously recognized. This provides new context to historic results including more recent (e.g., 2018-2021) till geochemistry completed by previous operators.

Alcona-Main

Mineralized deformation corridor over 1km strike by 200m wide consisting of multiple discrete zones of deformed volcanic rocks and shear parallel quartz veins open in all directions.

• A total of 18 channel samples where completed, anomalous gold mineralization was encountered in all channels.

• Confirm widespread Au-Ag mineralization at surface hosted in broad composite deformation corridors (200m) which is similar to the similar to the Goliath Deposit at Treasury Metals.

ABOUT THE DRAYTON-BLACK LAKE PROJECT

The Drayton-Black Lake Project is located near the town of Sioux Lookout in Northern Ontario and comprises more than 15,000 Ha within the Eagle-Wabigoon-Manitou ("EWM") Greenstone Belt along strike of and contiguous with Treasury Metals Inc.'s Goliath Gold-Silver Complex. There are numerous historic high-grade gold (silver, copper) prospects throughout the property within the Central Volcanic domain. All set within a broad multi-kilometer regional-scale deformation corridor with associated secondary and tertiary structural elements. Mineralization is typically shear-hosted quartz-carbonate veins with minor sulphides (1-5%). Locally, mineralized massive sulphide (Py +/- Cpy) occurrences have been documented. Some of the more sulphide rich Au + Au-Ag occurrences in the Southern Sedimentary domain have been notionally reclassified (e.g., Treasury Metal Goliath Deposit) as a hybrid or pre-orogenic atypical greenstone gold (POAGG).

Heritage employs a rigorous quality management system for field sampling and analysis. All samples and sample sites are described, photographed and geo-referenced and digitally archived at the time of sample collection. Material is securely bagged at the sample site and returned to the field office for secure storage. Sampled are delivered by Company personnel to the ALS laboratory in Thunder Bay, Ontario for prep. Samples are crushed (min. 1 kg) and pulverized (250 g; PREP-31A). Au values are determined by 50 g fire assay (Au-AA24), overlimit (Au) are treated with a gravimetric finish (Au-GRA22) and overlimit Ag are treated with acid digestion and ICP/FA finish (Ag-OG62). Multi-element analysis is provided by ICP-MS (ME-MS61). Blind duplicates, blanks, and CRM (Certified Reference Materials) are inserted on a regular basis and pulps and rejects are retained for check and duplicate analysis.
