Sankamap Metals Inc. (CSE: SCU) (‘Sankamap’ or the ‘Company’) further to the Company’s news release dated October 21, 2025, the Company continues to work towards the filing of its annual audited financial statements and management’s discussion and analysis for the fiscal year ended June 30, 2025 (the ‘Required Filings’).

The audit of Sankamap’s subsidiary is nearing completion and is expected to be finalized within the next few days. Sankamap has provided the auditor with all required planning materials and supporting documentation; however, the commencement of Sankamap’s audit in full remains dependent upon the completion of the subsidiary audit. From Sankamap’s perspective, all necessary preparations for the audit have been completed, and only potential adjustments, if any, are anticipated following the finalization of the subsidiary audit. Sankamap continues to anticipate that the audited financial statements will be completed and filed on or before November 28, 2025.

The Required Filings were due to be filed by October 28, 2025. In connection with the anticipated delays in making the Required Filings, the Company made an application for a Management Cease Trade Order (‘MCTO‘) under National Policy 12-203 Management Cease Trade Orders (‘NP 12-203‘) to the Alberta Securities Commission, as principal regulator for the Company, and the MCTO was issued on October 29, 2025. The MCTO restricts all trading by the Company’s CEO and CFO in securities of the Company, whether direct or indirect. The issuance of the MCTO will not affect the ability of persons who are not directors, officers or insiders of the Company to trade their securities. The MCTO will remain in effect until the Required Filings are filed or until it is revoked or varied.

The Company expects to proceed with the filing of its interim first-quarter financial statements shortly after the Required Filings have been completed and submitted.

Both the Company and its auditors are working diligently towards the completion and filing of the Required Filings, and the Company will provide additional updates.

The Company confirms that it intends to satisfy the provisions of the alternative information guidelines described in NP 12-203 by issuing bi-weekly default status reports in the form of a news release until it meets the Required Filings requirement. The Company has not taken any steps towards any insolvency proceeding and the Company has no material information relating to its affairs that has not been generally disclosed.

About Sankamap Metals Inc.

Sankamap Metals Inc. (CSE: SCU) is a Canadian mineral exploration company dedicated to the discovery and development of high-grade copper and gold deposits through its flagship Oceania Project, located in the South Pacific. The Company’s fully permitted assets are strategically positioned in the Solomon Islands, along a prolific geological trend that hosts major copper-gold deposits; including Newcrest’s Lihir Mine, with a resource of 71.9 million ounces of gold¹ (310 Mt containing 23 Moz Au at 2.3 g/t P+P, 520 Mt containing 39 Moz Au at 2.3 g/t indicated, 81 Mt containing 5 Moz Au at 1.9 g/t measured, 61 Mt containing 4.9 Moz Au at 2.3 g/t Inferred).

Exploration is actively advancing at both the Kuma and Fauro properties, part of Sankamap’s Oceania Project in the Solomon Islands. Historical work has already highlighted the mineral potential of both sites, which lie along a highly prospective copper and gold-bearing trend, suggesting the possibility of further, yet-to-be-discovered deposits.

At Kuma, the property is believed to host an underexplored and largely untested porphyry copper-gold (Cu-Au) system. Historical rock chip sampling has returned consistently elevated gold values above 0.5 g/t Au, including a standout sample assaying 11.7% Cu and 13.5 g/t Au²; underscoring the area’s significant potential.

At Fauro, particularly at the Meriguna Target, historical trenching has returned highly encouraging results, including 8.0 meters at 27.95 g/t Au and 14.0 meters at 8.94 g/t Au³. Complementing these results are exceptional grab sample assays, including historical values of up to 173 g/t Au³, along with recent sampling by Sankamap at the Kiovakase Target, which returned numerous high-grade copper values, reaching up to 4.09% Cu. In addition, limited historical shallow drilling intersected 35.0 meters at 2.08 g/t Au³, further underscoring the property’s strong mineral potential and the merit for continued exploration. With a commitment to systematic exploration and a team of experienced professionals, Sankamap aims to unlock the untapped potential of underexplored regions and create substantial value for its shareholders.

(TheNewswire)

Vancouver, British Columbia, November 5th, 2025 TheNewswire – Prismo Metals Inc. (the ‘ Company ‘ ) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce that Walnut Mines LLC, the owner of the Hot Breccia claims optioned as to 75% by the Company, has agreed to extend certain dates to complete cash payments and exploration expenditures.

Alain Lambert, CEO of Prismo said: ” Prismo remains firmly committed to advancing the Hot Breccia Project, located in the heart of Arizona ‘ s historic copper belt. We appreciate the cooperation of Walnut Mines LLC in extending certain milestone obligations, which provides the Company with additional flexibility as we assess a range of strategic alternatives. Each of these paths is designed to position Prismo to commence drilling on what we consider one of the most compelling copper exploration opportunities in Arizona and the broader United States. ‘

Dr Linus Keating, manager of Walnut Mines LLC, enthusiastically commented: ‘Walnut and Prismo remain firmly dedicated to advancing Hot Breccia towards drill discovery. Accomplishing that goal requires that we continue to work together and support each other. This extension will provide the necessary time, and better focus resources, to succeed at Hot Breccia.’

More specifically, the extensions are as follows: (i) extend the milestone date to complete exploration expenditures of $1,750,000 from January 31, 2026 to January 31, 2027; and (ii) extend the milestone date to complete exploration expenditures of $2,000,000 from January 31, 2027 to January 31, 2028 and (iii) extend the milestone date to complete the final cash payment of $275,000 to Walnut Mines LLC from January 31, 2026 to July 31, 2026.

Prismo ‘ s Hot Breccia project lies at the heart of the Arizona Copper Belt, which hosts several globally significant porphyry copper deposits.  Examples of these significant deposits are Freeport McMoRan’s Miami-Inspiration mining complex, BHP’s San Manuel mine, Rio Tinto and BHP’s Resolution deposit and others (see Figure 1).

Figure 1. Location of the Hot Breccia Project in the Arizona Copper Belt.

Historical drilling carried out in the mid to late 1970 ‘ s by a Rio Tinto subsidiary intersected high-grade copper mineralization at depths ranging from 640 to 830 meters below surface. Several holes targeted an area with a coincident magnetic high, believed to be caused by magnetite skarn that was cut in the drill holes and that occurs in xenoliths in cross cutting dikes exposed at the surface. Prismo believes those intercepts may represent the periphery of the upper portion of a large mineralized system.

Support for the Company ‘ s mineralization model at the project comes from several sources, including the results of historical drilling, geophysical surveys, distribution of dikes with xenoliths of Cu-bearing skarn, the 2023 ZTEM survey as well as the results of an AI study. The anomalous target area identified in Prismo ‘ s modelling measures 1,100 meters by 1,150 meters.

Dr. Craig Gibson, Chief Exploration Officer of Prismo stated: ‘ The copper exploration target at Hot Breccia has geophysical, geochemical and geological features characteristic of many porphyry copper deposits. The project area has a regional setting similar to BHP-Rio Tinto’s Resolution copper deposit located 40 kilometers to the northwest of Hot Breccia and which is considered to be one on the greatest copper discoveries in the history of North American mining. ‘ He added: ‘ The drill program is intended to drill through the entire prospective Paleozoic carbonate stratigraphy into the postulated porphyry body/breccia zone. The exploration team will take advantage of geological information provided by each hole during drilling to refine targeting of subsequent holes. ‘

Historical drill holes cut high grade skarn mineralization including 23 meters with 0.54% Cu at 640 meters depth (hole OC-1), 18 m with 1.4% Cu and 4.65% Zn at 830 meters depth (hole OCC-7), and 7.6 m with 1.73% Cu and 0.11% Zn at 703 meters and 4.6 meters with 1.4% Cu and 0.88% Zn at 716 meters (OCC-8).  Mineralization occurs within a several hundred-meter-thick altered zone hosted in favorable Paleozoic carbonate rocks that underly a sequence of Cretaceous andesitic volcanic rocks. These carbonates are the same rocks that host the high-grade copper mineralization at Freeport ‘ s nearby Christmas mine.  The historic drilling intersected a blind mineralized intrusion associated with the skarn mineralization, providing an immediate drill target that is believed to be the source of the mineralization at Hot Breccia (Figure 2). Several magnetic highs in the region surrounding the proposed intrusion may also indicated buried skarn mineralization and provide additional exploration targets.

About Hot Breccia

The Hot Breccia property consists of 1,420 hectares in 227 contiguous mining claims located in the world class Arizona Copper Belt between several very well understood world-class copper mines including Morenci, Ray and Resolution (Figure 1). Hot Breccia shows many features in common with these neighboring systems, most prominently a swarm of porphyry dikes and series of breccia pipes containing numerous fragments of well copper-mineralized rocks mixed with fragments of volcanic and sedimentary derived from considerable depth. Prismo performed a ZTEM survey last year that identified a very large conductive anomaly directly beneath the breccia outcrops.

Sampling at the project has shown the presence of copper mineralization associated with dacite dikes that transported fragments of strongly mineralized carbonate rocks to the surface from depths believed to be 400-1,000 meters. Drilling deep holes is necessary to tap into the source of these mineralized fragments found at surface.

Assay results from historic drill holes are unverified as the core has been destroyed, but information has been gathered from memos, photos and drill logs that contain some, but not all, of the assay results and descriptions.  Technical information from adjacent or nearby properties does not mean nor does it imply that Prismo will obtain similar results from its own properties.

Data on previous drilling and geophysics is historical in nature and has not been verified, is not compliant with NI 43-101 standards and should not be relied upon; the Company is using the information only as a guide to aid in exploration planning.
