LIGHTHOUSE GOLD PROVIDES CLARIFICATION REGARDING HISTORICAL DRILL RESULTS AT SARDINE HILL AND UPDATE ON PRIVATE PLACEMENT

Further to the news releases dated June 15, 2026, and Oct. 20, 2026, respecting the Mariwa-Sardine Hill-Lower Cuyuni gold property located within the Oko gold district in Guyana, Lighthouse Gold Inc. is providing clarification regarding certain historical drill results referred to in the prior releases. The company also announces an update on the timing of the closing of its previously announced private placement.

Clarification regarding historical drill results

The prior releases referred to historical drilling at the Sardine Hill zone, including a reported mineralized interval of 113.5 metres grading 1.39 grams per tonne gold and a deeper interval of 93 metres grading 0.69 g/t gold. Upon further review, the company has not been able to confirm that the drill hole or holes from which the historical drill results were derived are located within the boundaries of the property. Accordingly, readers should not assume that the historical drill results are located on the property, and the references to the historical drill results in the prior releases should be read subject to this clarification.

The historical drill results are drawn from historical reports prepared by International Roraima Gold Corp. (September, 1997) and AngloGold (September, 2002). The historical reports predate, and are not compliant with, National Instrument 43-101 (Standards of Disclosure for Mineral Projects) and do not identify drill hole locations by UTM co-ordinates, but instead by reference to a historical local grid. The location of the historical drill holes relative to the property boundaries is therefore not based on accurate UTM positioning, known used horizontal datum and reference spheroid, and is subject to greater uncertainty than would otherwise be the case.

Until the historical drill holes can be reliably located relative to the property boundaries, the company is not in a position to comment on whether the historical drill results lie inside or outside of the property. As part of its previously announced compilation and validation of historical exploration data, the company intends to locate the historical drill holes relative to the property boundaries and will provide an update once that work has been completed. However, given the analysis of all historical geological, geochemical and geophysical data, the management of the company is still of the technical opinion that the property merits significant modern exploration activities and studies, inclusive of drilling and intends to pursue such activities and studies from the proceeds of the announced private placement.

The company reiterates that the historical drill results and other historical exploration results referred to in the prior releases have not been independently verified by the company, were not prepared in accordance with National Instrument 43-101 and should not be relied upon as indicative of future exploration success. The company has not completed sufficient work to verify the historical information, and a qualified person has not done sufficient work to classify the historical estimates or results as current mineral resources or reserves.

The scientific and technical information contained in this news release has been reviewed and approved by Gregory Smith, PGeo, a director of the company, a qualified person as defined by NI 43-101.

Private placement update

The company also announces, further to the news releases dated Oct. 22, 2026, and Oct. 23, 2026, that its previously announced private placement is continuing. The company now expects to close the private placement during the week of Nov. 9, 2026, rather than on or about Nov. 4, 2026, as previously announced. Closing of the private placement remains subject to customary conditions, including acceptance by the Canadian Securities Exchange, and there is no assurance that the private placement will be completed on the terms described or at all.
