Touchstone Exploration Retail Offer

CALGARY, ALBERTA (October 24, 2025) - Touchstone Exploration Inc. ("Touchstone" or the "Company") (TSX, LSE: TXP) announces a retail offer to raise up to £0.68 million via BookBuild (the "Retail Offer") by way of the issue of up to 6,181,818 new common shares with no par value ("Common Shares") in the capital of the Company (the "Retail Offer Shares") at an issue price of 11 pence per Retail Offer Share (the "Issue Price").

In addition to the Retail Offer, the Company is also conducting a placing of new Common Shares (the "Placing Shares" and together with the Retail Offer Shares, the "New Common Shares") at the Issue Price (the "Placing" and together with the Retail Offer, the "Issue"). A separate announcement has been made regarding the Placing and its terms. For the avoidance of doubt, the Retail Offer is not part of the Placing.

The Issue Price represents a discount of approximately 2.2 per cent to the closing share price of 11.25 pence per existing Common Share on October 23, 2025, being the last practicable date prior to the announcement of the Placing.

The proceeds of the Retail Offer will be utilised in the same way as the proceeds of the Placing, as set out in the separate announcement of the Placing released by the Company at 7.00 a.m. on October 24, 2025.

The Retail Offer is conditional on the New Common Shares to be issued pursuant to the Retail Offer being admitted to trading on the Toronto Stock Exchange ("TSX") and the AIM market ("AIM") operated by the London Stock Exchange ("Admission"). Admission of the New Common Shares pursuant to the Retail Offer is expected to take place on or around 8.00 a.m. (London time) on October 30, 2025. Completion of the Retail Offer is conditional, inter alia, upon the completion of the Placing.
