Heritage Mining begins 2024 exploration program at DBL

2024-05-22 11:01 ET – News Release

Mr. Peter Schloo reports


Heritage Mining Ltd. has commenced the 2024 exploration program at its flagship Drayton Black Lake (DBL) property. The company believes the progress achieved to date represents important milestones for systematic exploration in one of the last underdeveloped greenstone belts in Northwestern Ontario.


  • DBL target — zone 3:
    • 3-D model for evaluation and confirmation drilling of the historical 1980 not National Instrument 43-101-compliant mineral resource of 70,000 tonnes at 8.16 grams per tonne (g/t) gold (Au) high-grade ore shoot, near surface;
    • Property expansion along zone 3 gold-bearing contact — zone 3 through to zone 10.
  • DBL exploration update:
    • Soil sampling (spatiotemporal-gas-hydrocarbon (SGH)) and mapping commencement, results pending;
    • Diamond drilling to commence late Q2 2024.
  • Structural interpretation and geological modelling: Property-wide structural interpretation and 3-D geological model (32 kilometres east-west by 25 km northwest by three km vertical extent).

« We are excited to share the progress we are making at DBL, with emphasis on zone 3 target area. A testament to the systematic exploration approach ahead of drilling. Zone 3, an area that has received no additional drilling since 1937, through 3-D modelling is evidence to the potential of this project. The expansion along the gold-bearing contact zone 3 to zone 10 opens up new opportunities for discovery. With boots on the ground and field activities in full swing, we are well-positioned to advance our exploration program and unlock the full potential of our properties, » commented Peter Schloo, president, chief executive officer and director of Heritage.

DBL project — zone 3 target area

Zone 3 historical highlights to be confirmed in this year’s exploration program by diamond drilling.

Zone 3 Contact Extension Secured

Zone 3 mineralization is associated along the Contact of the Mafic Volcanics and Batholith. The Company therefore staked claims along the contact in order to secure continuity totaling ~+4km in potential strike length.

Exploration Plan Update

Soil Sample – Spatiotemporal-Gas-Hydrocarbon type analysis (SGH)

The orientation grid consisted of 88 samples taken at 25m spacing on a grid pattern. This survey targeted known mineralization at surface near the Alcona mine to determine the practicality of spatiotemporal-gas-hydrocarbon type analysis (SGH) in the local terrane. This will ensure the survey properly picks up on mineralization before initiating a property-wide survey later this summer.

Diamond Drilling is set to commence no later than June 30, 2024.

Property-wide Structural Interpretation & 3D Geology Model

Structural Interpretation:

The interpretation is heavily slanted toward the identification of favourable zones for hosting orogenic-style gold. The belt hosts geometries consistent with two major deformation events, mineralisation during either event is possible based on current information.

First pass interpretation resulted in 20 zones of structural complexity with potential to host low mean stress sites applicable to both (Figure 9).

« Gold mineralisation appears to be spatially coincident with the second-order sigmoidal, across-belt structures in the eastern end of the belt. In the west of the project area, the geometry of folded thrusts sitting at the end of, and possibly above, a major syntectonic granite pluton, has geometric affinities with the multi-million ounce Kanowna Belle gold deposit in Western Australia. Note that similar macroscale geometries to those inferred for the HML ground have been identified in Proterozoic and Archaean granite-greenstone belts globally and host world-class orogenic-style gold deposits, reinforcing the gold-discovery potential of HML’s tenement package. » Commented Dr. Brett Davis, Advisor to the Company

3D Geological Model

The Company has created the first ever property-wide 3D geological model (32km EW by 25km NW by 3km vertical extent) to model the property’s historic database, which dates back to the early 1900s and totals over 28 kilometers of drilling to date. The modelling of the database will enhance the company’s geological understanding of the property, providing new insights into styles of mineralization and their geologic controls. It is expected to unlock further targets to test in the Company’s active 2024 program.
