Signature to drill 3,000 m in fall 2025

Mr. Dan Denbow reports SIGNATURE RESOURCES REFINES 2025 FALL DRILLING TARGETS USING 3D IP SURVEY, ANNOUNCES EQUITY RAISE Signature Resources Ltd. has provided details of the proposed diamond drill hole program to be completed in the fall of 2025. It is contemplated that the company would drill six DDHs for approximately 3,000 metres. One of the key findings from the National Instrument 43-101 technical report published July 31, 2025, was that the deposit remained open laterally along the east/west trend and at depth. The company has defined this drill program based upon the modelling work culminating from historical drilling results and areas of interest defined by geophysical work looking at the strong correlation of mineralization with high chargeability and low resistivity. The targets identified for the coming program are considerably larger than the ones associated with drilling done to date. "The company remains focused on completing fundamental work that will continue to demonstrate the potential of significantly expanding the mineral resource of the Lingman Lake property. The 3-D IP survey identified anomalies which correlated to known mineralized zones. To this end, part of the drill program will test the west zone 590 metres west of DDH LM24-13 and 14, which were the most westerly holes drilled in 2024, and to a vertical depth of up to 475 m. This work is another example of the thorough fundamental work that has been undertaken to prove the potential of the Lingman Lake deposit, which will also assist with vectoring regional targets," said J. Dan Denbow, CFA, president, chief executive officer and director. The company is also announcing that it is undertaking a non-brokered private placement of flow-through units and non-flow-through units for gross proceeds of up to $3-million. It is anticipated that insiders will subscribe for at least 20 per cent of the offering. 3-D Alpha induced polarization and mag surveys A geophysical interpretation report was produced by Simcoe Geoscience Ltd. on Dec. 18, 2021, that identified a number of anomalies based upon the analysis of a 3-D Alpha IP wireless time domain distributed induced polarization and ground magnetic survey. The survey comprised an area of three kilometres (east/west) by 1.6 kilometres (north/south) and to a depth of 600 metres covering the main area surrounding the Lingman Lake mine. As a result of the 2024 drill program and with continuing geological model refinement, correlation with the 3-D IP survey has identified many areas of opportunity, laterally along the currently defined mineralized zones and untested areas north and south of the currently defined mineralized zones. The objective of the survey was to map the chargeability, resistivity and total magnetic field intensity responses associated with disseminated and sub-massive sulphides associated with structurally controlled gold mineralization similar to historic west, north, central, south and the 11650N zones documented on the property. 2025 fall drilling program For the past two years, the company has been focused on upgrading its historical database through digitizing its data, increased mapping of the area, and over all improving its ability to deliver better identification and delineation of the mineralized zone. The 2024 drill program was purpose built for the completion of the company's initial mineral resource estimate delivered earlier this year. Signature is able to combine all the historical data, resource modelling and the geophysical work from the 3-D Alpha IP study to improve targeting along trend and at depth. The objective of the fall program is to continue extending the resource along the east-west strike and to test the extent of mineralization at depth below the currently defined resource. Target Section-A (507780E) is located at the east end of the Lingman Lake gold zones and slices anomaly AZ three feet, being 400 m long, more or less in the middle of it. High chargeability is associated with low resistivity where the north zone anomaly converges at depth with the larger IP feature just as in the above Section 507600E. Two holes along a drill fence are planned. One hole will be about 500 m in length drilled to vertical depth of 410 m below surface, designed for a separation from 88 to 76 m of about 90 m. The other hole will be about 600 m in length to vertical depth of 490 m with a separation from the previous mentioned hole of about 215 m. Section 507600E is in the area of the merging of the south, central and north zones, as well as the convergence of IP zones both in chargeability and resistivity. It is where significant mineralization was encountered in drill holes LM 24-06 and 07. High chargeability is associated with low resistivity as defined in anomalous area AZ-3f. A hole of 500 m to 550 m is planned to intersect the downdip extensions of all of the zone with the south zone expected at a 220-metre vertical depth and the north zone at 325-metre vertical depth. The anomalous zone AZ-3a to 3b correlates with the 11650 and south zone mineralized shear alteration structures. The IP responses consist of high chargeability, low resistivity and moderate to high magnetic susceptibility. The south zone in the area of this section has a horizontal width at and near surface exceeding 50 m. A 600-metre drill hole is planned for this section to intersect the 11650, south, central and north zones. The hole will likely be planned to hit the south zone at a vertical depth of 190 m and the north zone at a vertical depth of 300 m. Several shallow drill targets (AZ-1b, 2a and 3b, and DZ-2) occur near the top edge of the anomaly interest, which has moderate IP responses that are more similar to observations in the central zone east of the diabase dike. Drill holes LM24-13 and 14 which are located 230 m east of this section likely intersected the near-surface expression of the anomaly. The elevation (275-metre depth) of the deep zone (DZ-3b) and target Az-2aa are planned to be tested by a 500-metre drill hole. The anomalous zone AZ-1a to 1e correlates with north zone and west zone shear alteration structures with AZ-1a located at the western end of the zone. The anomaly of interest in Section 505900E is anomaly AZ-1a with a deep zone (DZ-1a) drill target. The anomaly is interpreted to be an area of high chargeability with low resistivity and strong magnetic susceptibility response situated along the northwestern strike extension of the west zone. This section is situated 590 m northwest of drill holes LM24-13 and 14. A 500-metre drill hole will be designed to intersect the target at a vertical depth of 290 m. Equity financing The company is offering a non-brokered private placement of flow-through units and non-flow-through units for gross proceeds of up to $3-million. It is anticipated that insiders will subscribe for at least 20 per cent of the offering. Each FT unit is being offered at six cents and is composed of one share of common stock of the company and one-half of one common share purchase warrant. Each whole warrant will be exercisable for one additional common share at a price of 10 cents per warrant share for a period of 12 months following the date of issuance. Each NFT unit is being offered at 5.5 cents per share and is composed of one share of common stock of the company and one-half of one common share purchase warrant. Each whole warrant will be exercisable for one additional common share at a price of 10 cents per warrant share for a period of 12 months following the date of issuance. All securities issued pursuant to this proposed private placement will be subject to the exchange hold period and legend accordingly. The net proceeds from the offering will be used for the 2025 fall drilling program, loan repayment and general working capital purposes. It is expected that over half of the proceeds will be used for the drilling program and the rest for the loan repayment and general working capital purposes, including accrued invoices to a non-arm's-length party. The company may pay up to 7 per cent of the gross proceeds as finders' fees. None of the proceeds will be used for investor relations service providers. Amended related-party loan The company also announces that it has amended the loan agreement with a related party to provide interim financing for general corporate activities dated Jan. 2, 2025. The loan maturity date has been extended to Oct. 30, 2025. The loan is provided on a non-cost basis to the company with no interest, finders' fees or bonuses payable to the lender. The company anticipates repaying the loan through future equity financings. The company confirms that the loan agreement meets the exemption requirements and complies with TSX Venture Exchange Policy 5.9 and Multilateral Instrument 61-101. The transaction remains subject to the approval of the TSX Venture Exchange.
