Heritage Mining Confirms Visible Gold at Melba Mine Project

VANCOUVER, BC — February 12, 2026 — Leads & Copy —

Heritage Mining Ltd. has announced the confirmation of visible gold in core from its Melba Mine Project. The discovery was made outside the current internal model previously announced on February 9 and 10, enhancing the exploration potential of the project located in Northeastern Ontario, Canada.

The company (CSE: HML FRA: Y66) identified fine-grained visible gold in core sample ML3840-001 at approximately 31 meters. Four such identifications have been made, and the core is undergoing logging and sampling.

Peter Schloo, President, CEO, and Director of Heritage, commented that the identification of additional visible gold enhances the exploration upside and positive potential of Melba early in the initial exploration program. He anticipates further updates soon.

The Melba Project is situated about 22 kilometers northeast of Kirkland Lake and 90 kilometers southeast of Timmins, encompassing approximately 3,886 hectares. It lies along the Ross Fault, a splay off the Porcupine-Destor Fault Zone, associated with development-stage and historic producing gold mines, including McEwen Mine (Grey Fox Mine, +1Moz Au) 22km away and the Ross Mine (+1Moz Au) 16km away.

Heritage Mining has identified at least four instances of fine-grained gold mineralization within a shallow, previously unidentified zone. The gold is found in sheared quartz veinlets within a silicified quartz diorite intrusion, accompanied by up to 3% pyrite across a 2-meter interval.

The company adheres to a strict QA/QC protocol for handling, sampling, transportation, and analyses. Chain-of-custody protocols ensure sample security until delivery at the laboratory. Drill core is boxed, sealed, and labeled at the drill rig site, then transported to the onsite logging facility.

Drill core, NQ size, is systematically cut in half, with a qualified geologist marking intervals for sampling. Sample lengths are typically 1.0 meter, adjusted to a minimum of 0.5 meter to respect lithological or mineralogical contacts. Technicians saw the core along the geologist's cutting lines, retaining one half as a witness sample and submitting the other for analysis in sealed bags.

Samples are submitted for gold determination by PhotonAssay to Paragon Geochemical - Timmins, an ISO/IEC 17025:2017 accredited laboratory. Paragon's PhotonAssay procedure involves sample logging, drying, crushing, and riffle splitting, followed by a non-destructive gold analysis method using high-energy X-rays with a gold detection range from 0.015 ppm to 350 ppm. Heritage may perform multi-element assays on selected samples based on the initial gold results, using a 48MA-MS analysis for a 48-element suite.

The drill program design, QA/QC, and interpretation of results are performed by qualified persons using 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. All Heritage Mining results have passed stringent quality control protocols. The company has not completed economic evaluations of its Melba Project, which currently has no resources or reserves.

Mitchell Lavery P. Geo, Strategic Advisor for the Company, serves as the qualified person.

Heritage Mining Ltd. is a Canadian mineral exploration company advancing its Ontario Project Portfolio in Northwestern and Northeastern Ontario. The Drayton-Black Lake, Contact Bay, and Scattergood projects are located near Sioux Lookout, while the Melba Property is located near Ramore, Ontario.
