(\"Horizon\"\nor the \"Company\") (TSXV: HPL) (FRA: HPM) (Tradegate: HPM) is pleased to\nannounce that further to its press release dated July 23, 2026, its wholly\nowned Polish subsidiary, Energia Karpaty Zachodnie sp. z o.o. (\"EKZ\"),\nconfirms that the rig mobilization and installation is complete and the\nre-entry operations have commenced at the Lachowice 7 (L7) wellsite.\n\nThe L7 workover program is designed to confirm the long-term production flow\npotential of the naturally fractured carbonate reservoir at Lachowice. To date\nthe Company has drilled out the cement and mechanical suspension plugs and run\na milling assembly into the hole to a depth of 2,706m. Two casing pressure\ntests were conducted, and both confirmed the physical integrity of the\nwellbore. With this confirmation, the company can now move forward with the\nbalance of the program.\n\nThe work program continues as follows:\n\n * Removal of the existing downhole packer and completion equipment\n * Re-perforate the naturally fractured, Upper Devonian aged carbonate reservoir\nsection (with a gross interval of 65m) with new perforations\n * Stimulate using a diverted acid stimulation and then production test the well\nto confirm sustainable production flow performance.\n * Suspend the well for production upon completion of the Phase 1 development\nplan.\nThe workover program is on track, and the stimulation and production testing\nare expected to commence near the end of August and continue into early\nSeptember 2026 as previously disclosed.\n\nRoger McMechan, Chief Operations Officer of Horizon, commented: \"Confirming\nthe integrity of the well casing mitigates one of the key risks in re-entering\nthe well. We look forward to executing and completing the workover and\nproduction testing safely and efficiently to confirm the long-term production\ncapability of the Lachowice gas accumulation, which we believe has the\npotential to become a significant new domestic source of natural gas for\nPoland.\"\n\nThe Company will provide additional updates as operations progress.\n\nAbout Horizon Petroleum Ltd.\n\nCalgary-based Horizon is focused on the appraisal and development of natural\ngas reserves and clean energy sources to increase energy independence and\nsecurity in Europe.
