Heritage Intersects Multiple High-Grade Intercepts Up to 21.74 g/t Au in Drill Core
from Multiple Visible Gold Intersections, at the Melba Project
VANCOUVER, BC, May 6, 2026 – Heritage Mining Ltd. (CSE: HML FRA: Y66) (“Heritage” or
the “Company”) is pleased to announce results from the ongoing drilling program at Melba Project ,
located ~22km northeast from Kirkland Lake and 90km southeast of Timmins in Northeastern Ontario,
Canada. Assays are reported from drill hole ML3855-001, which returned:
• 9.34g/t Au over 2.00m from 67m (Including 18.25g/t Au over 1.00m from 67.0m), visible
gold noted in core (Figure 1,3)
• 6.07g/t Au over 2m from 92.50m (Including 21.74g/t Au over 0.50m from 93m) visible
gold noted in core (Figure 1,2,3)
• 1.33g/t Au over 1.5m from 97m visible gold noted in core (Figure 1, 2, 3)
Drill hole M3800-001 has been completed and core is being processed for assay (Figure 3). M3800-
002 will commence drilling soon and the Company will be undertaking oriented core measurements
to determine the strike and dip of the multiple vein sets.
Melba Project – Multiple Visible Gold Occurrences Return High-Grade Gold

“Multiple high-grade intervals have been returned from multiple visible gold intersections in drill hole
ML3855-001. Furthermore, recently completed drill hole ML3800-001 tested the Company’s concept
of a “stacked vein system” at Melba. Drill hole ML3800- 002 will test deeper levels of the veins
intersected in ML3800-001. We continue to believe that the broader zones of quartz veins and veinlets
could converge into a much larger mineralized system at Melba.” Commented Peter Schloo, President,
CEO and Director of Heritage.

Geological Commentary:
Gold Mineralization occurs within a Rhyolitic Tuff/Fragmental lithology comprising yellow-grey
strongly siliceous, fragmental lithologies interbedded with narrow intervals of lithic wacke. Visible
gold was observed in DDH ML3855-001 at 67.80m in a brecciated/sheared quartz vein (70deg) TCA
that returned 9.34g/t Au over 2.00m from 67m (Including 18.25g/t Au over 1.00m from 67.0m)
(Figure 1,3). The “Blue Vein” is a brecciated, sheared quartz vein with localized, cm-scale fault
gouge. Multiple occurrences of visible gold were also observed in the Blue Vein (ML3855-001),
which assayed 6.07g/t Au over 2m from 92.50m (Including 21.74g/t Au over 0.50m from 93m).
Visible gold occurrences are shown in Figures 1-3.
The mineralized zone is strongly structurally controlled, containing multi-generational veins hosting
breccia-, shear- and extension-related features. Vein morphologies and overprinting relationships are
products of multiple fluid ingress events, which are characteristic of large orogenic-style gold
deposits globally. Diamond drill intersections suggest a braided system of shear-hosted veins with
intervening altered wall-rocks in the damage zones. The braided character of the veins and the
historical mapping from Melba underground workings have imparted variable orientations to
mineralized and wall-rock structures, which will be assessed with a forward program of oriented core
drilling.
The Melba project is located ~22km northeast from Kirkland Lake and 90km southeast of Timmins in
Northeastern Ontario, Canada. The project is comprised of ~3,886Ha. Melba lies along the Ross Fault,
which is a splay off the Porcupine-Destor Fault Zone and is associated with development -stage and
historic producing gold mines: McEwen Mine (Grey Fox Mine, +1Moz Au) ~22km away, and the Ross
Mine (+1Moz Au) ~16km away.
Technical Program
Heritage Mining adheres to a strict QA/QC protocol for handling, sampling, sample transportation and analyses.
Chain-of-custody protocols are designed to ensure security of samples until their delivery at the laboratory.
Drill core was boxed, covered and sealed at the drill rig site. Core boxes were labelled with the official drillhole
name and identified in numerical sequence starting from beginning of the hole to the end. Wooden blocks with
the corresponding down hole meterage were inserted after every drill run. Drill core boxes were transported by
drilling contactors to the onsite logging facility where Company personnel would take over the core handling.
Sampling, Sub-sampling, and Laboratory Analysis for Heritage Mining Melba Project. All drilling at the Melba
project recovers NQ core. Drill core is systematically cut in half using a diamond saw. A qualified geologist
examines the drill core, marking intervals for sampling and indicating the cutting line. Sample lengths are
typically 1.0 metre, adjusted to a minimum length of 0.5 metre as necessary to respect lithologi cal and/or
mineralogical contacts and to isolate narrow veins or structures that may contain higher-grade mineralization.
Technicians saw the core along the cutting lines determined by the geologist. One half of the core is retained as
a witness sample, while the other half is submitted for analysis. Individual sample bags are securely sealed and
placed into sealed rice bags, which are then clearly marked with their contents. Heritage Mining submits samples
for gold determination by PhotonAssay to Paragon Geochemical - Timmins. (“Paragon”). Paragon operates
under a commercial contract with Heritage Mining. Drill core samp les are shipped to Paragon for sample
preparation at their facilities in Timmins, Ontario. Paragon is an ISO/IEC 17025:2017 accredited laboratory for
the PhotonAssay method in addition to a variety of diverse metal determination methods. Analytical Procedures
The Paragon procedure for PhotonAssay involves lab applying preparation codes INV-SAM (sample logging
via barcode), PREP-PKG (weigh, dry at 100C, crushing to 70% passing 2mm, riffle split ~500g into a PA jar
and 250g for pulverization to 85% passing 75 micr on) followed by analytical code Au- PA01 which is a non -
destructive gold analysis method using high- energy X -rays with a gold detection range from 0.015 ppm to
350ppm. After gold assays are returned, Heritage then may choose to perform multi-element assays on selected
samples based on the gold results first with Paragon. In these cases, an aliquot is taken from the previously
prepared 250g split for analysis by 48MA-MS (4 acid digestion followed by multi-element ICP-MS analysis for
a 48 element suite).
