Signature Resources Announces Results of Gold Deportment Study and Appointment of Stacy Freudigmann to Advisory Board January 20, 2026 5:35 PM EST | Source: Signature Resources Ltd. Toronto, Ontario--(Newsfile Corp. - January 20, 2026) - Signature Resources Ltd. (TSXV: SGU) (OTCQB: SGGTF) (FSE: 3S30) ("Signature" or the "Company") is pleased to announce results from an independent gold deportment and mineralogical study completed by SGS Canada Inc. ("SGS") on composite samples from the four main identified gold zones within the Company's Lingman Lake Gold Project in northwestern Ontario. Highlights from the deportment study: - Gold occurs primarily as free milling gold and gold-silver alloys in the high grade portion of the system, consistent with other Canadian greenstone-hosted gold systems. - The majority of the gold grains are exposed or partially exposed, indicating favorable processing characteristics (P80 passing ~150 micron ("µm")). - Samples returned gold recoveries ranging from 92.6% - 96.6% across the four gold zones. - The association between gold mineralization and arsenopyrite is minimal with less than 1% by weight in three samples, and 2.2% by weight in the fourth sample. - Results suggest comparable gold metallurgy across multiple higher-grade geological domains at Lingman Lake.

This study was a significant step in advancing our understanding of the mineral potential and geology of the deposit, and in conjunction with the recently completed initial mineral resource estimate (MRE), provides fresh insights into the Lingman Lake project. In addition, the Company wanted to reconcile the gold associations documented in the Department of Mines & Resources Report completed in 1948, that implied a gold-arsenopyrite association at Lingman Lake. "Our objective with this study was to understand where the gold is present in the system, how it occurs and gain some initial insights to guide on potential recovery of mineralization. Despite a fairly coarse grind size, the results indicate that the higher-grade portion of the gold mineralization at Lingman Lake is largely exposed and would respond to gravity and leaching. These are encouraging technical indicators at this early stage of the project. The appointment of Stacy Freudigmann as a member of the advisory board comes at an important time in our advancement of the property and reflects our growing confidence in the Lingman Lake project. Stacy's vast experience in metallurgical studies and project development and his counsel in tailoring our metallurgical programs will be invaluable as we advance the project forward towards feasibility and eventually production. We believe his willingness to join our journey is a great compliment to our Company." _Dan Denbow – President and CEO_ The sampling comprised composite samples from high grade sections representing the four main identified gold zones. The mineralogical test work was undertaken using a target grind of 80% passing ~150 µm. The aim of the initial sampling was to collect material to gain an understanding of the primary gold association and deportment, focusing our initial investigation on the high-grade portion of the deposit. Additional studies will be completed on the lower grade mineralization moving forward in order to confirm those associations and recoveries. This information is considered an important incremental step in defining potential process routes and will further the understanding of the metallurgical response through the entire deposit.

Test work included chemical assays, mineralogical characterization, heavy liquid separation (gravity concentration), microscopic gold grain analysis, and cyanide leach testing. The study demonstrated that a significant portion of the high-grade gold can be recovered using gravity methods, with additional recovery achieved through standard cyanide leaching of the float tails. Based on the combined mineralogical and metallurgical assessment, SGS estimated overall gold recoveries would likely range from approximately 79.8% to 96.6%. Figure 3 Illustrates the initial recoveries using these methods. Microscopic analysis further indicated that most gold grains are not locked within sulphide or silicate minerals.

Overall, the bulk mineralogy data correlates with the chemical assay results (Figure 4) reflecting a systematic transition from the silica-dominated WZB to feldspar and chlorite rich NZB, then to SZA with additional amphibole and calcite and finally to CZA, which is characterized by major dolomite content. The high silica and dolomite associations in the WZB and CZA respectively are indicative of an active hydrothermal system precipitating gold within changing temperature-pressure conditions. All four samples displayed only trace amounts of arsenopyrite. **Figure 4 - Chemical Characteristization of the Four Composite Samples** To view an enhanced version of this graphic, please visit: https://images.newsfilecorp.com/files/8296/280987_fig4signatureresource.jpg Source: SGS Inc - Report 21021-01 - Page iv The comprehensive characterization of gold minerals detected by TIMA scanning using the polished section of the four composite samples is shown in Figure 5.
