Horizon Minerals Ltd (ASX: HRZ) has announced the results of its Share Purchase Plan (SPP), which closed on 10 March 2026. The SPP raised approximately $4.65 million, in addition to the successful $175 million placement to new and existing institutional and sophisticated investors announced on 19 February 2026. The SPP offered eligible shareholders the opportunity to subscribe for a maximum value of $30,000 worth of new fully paid ordinary shares at a price of $1.08 per share, which was the same price paid by investors under the placement. The Company received valid applications from eligible shareholders for 4,306,909 new SPP shares, representing a shortfall of approximately 4,925,350 shares. Horizon Minerals has reserved the right to place any shortfall shares at its discretion, subject to compliance with ASX Listing Rules and shareholder approval. Managing Director Grant Haywood thanked existing shareholders for their ongoing support and participation in the SPP, stating that the additional funds raised will supplement the transformational placement completed earlier in the month as the Company progresses development of the Black Swan processing hub.
