The visible gold was found at a depth of 72.40m within an 8m shear zone. Due to favorable mineralization, the drill hole has been extended to approximately 150m. The company is awaiting assay results and adheres to strict QA/QC protocols for sample handling and analysis. The Melba Project is situated near historic gold mines and covers an area of approximately 3,886 hectares." datetime: "2026-03-12T10:00:04.000Z" locales: - [zh-CN](https://longbridge.com/zh-CN/news/278859474.md) - [en](https://longbridge.com/en/news/278859474.md) - [zh-HK](https://longbridge.com/zh-HK/news/278859474.md) --- # Heritage Confirms the Third Visible Gold Occurrence in Core and Extends Drill Hole to Length ~150m at Melba Project (TheNewswire) VANCOUVER, BC, March 12,2026 – TheNewswire– Heritage Mining Ltd. (CSE: HML FRA: Y66)(“Heritage” or the “Company”) is pleased to announceconfirmation of more Visible Gold in Core in sampled Diamond Drillhole ML3840-003 from 72.40m within an approximate ~8m shear zone atthe Melba Mine Project (“Melba”) with its ongoing diamond drillprogram (Figure 1,2). Melba Project – VisibleGold: Figure 1: ML3840-003 at 72.40m, visible gold atmillimeter scale “The identification of the thirdinstance of visible gold within an ~8m shear zone at ~72m depth isvery encouraging. We have also extended the planned depth ofML3840-003 to ~150m due to favourable mineralization, assays pending.We look forward to updating our stakeholders on additional explorationresults in short order.” Commented PeterSchloo, President, CEO and Director of Heritage.

The target zone is a shearedfelsic volcaniclastic and conglomerate contact. Melba, located ~22km northeast from Kirkland Lake and90km southeast of Timmins in Northeastern Ontario, Canada. The projectis comprised of ~3,886Ha. Melba lies along the Ross Fault, which is asplay off of the Porcupine-Destor Fault Zone and is associated withdevelopment stage and historic producing gold mines: McEwen Mine (GreyFox Mine, +1Moz Au) ~22km away, and the Ross Mine (+1Moz Au) ~16kmaway. 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 lithological 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 samples 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 micron) 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). \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ Quality Assurance/Quality Control (QA/QC). The drill program design, QA/QC, and interpretation of results are performed by qualified persons employing a rigorous QA/QC program consistent with industry best practices. Standards and blanks account for a minimum of 10% of the samples, in addition to the laboratories’ internal quality assurance programs. Quality Control data are meticulously evaluated upon receipt from the laboratories for any failures. Appropriate corrective action is taken if assay results for standards and blanks fall outside allowed tolerances. All results disclosed by Heritage Mining have successfully passed the Company’s stringent quality control protocols. The Company does not recognize any factors of drilling, sampling, or recovery that could materially affect the accuracy or reliability of the assay data disclosed. The assay data disclosed in this press release have been verified by the Company’s Qualified Person against the original assay certificates. Heritage Mining notes that it has not completed any economic evaluations of its Melba Project , and the project does not currently have any resources or reserves. Qualified Person Mitch Lavery P.
