VANCOUVER, British Columbia, July 2, 2025 (GLOBE NEWSWIRE) – DMG Blockchain Solutions Inc. (TSX-V: DMGI) (OTCQB: DMGGF) (FRANKFURT: 6AX), a vertically integrated blockchain and data center technology company, today released its preliminary operational results for June 2025: - Bitcoin mined: 23 BTC (down from 31 BTC in May 2025) - Hashrate: 1. 56 EH/s (down from 1. 89 EH/s in May 2025) - Bitcoin balance: 341 BTC (down from 350 BTC in May 2025) In June 2025, DMG’s realized hashrate declined 18% due to an unscheduled nearly two-day electrical outage at its Christina Lake facility and ongoing challenges with its hydro infrastructure. A regional lightning storm caused a main substation breaker to trip, necessitating extensive repairs. Additionally, manufacturer quality control issues led to contamination-related downtime in DMG’s hydro infrastructure, which is actively being resolved. The Company expects that with further servicing and monitoring, the hydro mining capacity’s hashrate can approach its 0. 4 EH/s potential, even during summer heat, as the hydro miners are designed to operate at ambient temperatures above 40°C though at reduced efficiency. Leveraging experience from its initial 6-megawatt hydro mining container build-out, DMG plans to source new hydro infrastructure from alternative manufacturers for the planned expansion at Christina Lake. The Company will retain existing electrical distribution and shelving while procuring key hydro components from top-tier vendors to facilitate the transition from air-cooled to direct liquid-cooled mining and improve supply chain and integration quality control. DMG intends to build a pilot hydro system this summer at Christina Lake ahead of its goal to expand to 3 EH/s by the end of 2025. As of June’s end, DMG’s bitcoin holdings totaled 341 BTC. The Company sold bitcoin during the month to fund operations and reduce its loan balance with Sygnum Bank, in line with previous guidance. New Bitcoin Mining Site Agreement Outside British Columbia DMG has executed a binding agreement to develop a new data processing center powered by low-cost renewable energy in a Canadian province outside British Columbia, supporting its long-term strategy to locate mining where energy costs are minimal. Once operational, the new site is expected to add approximately 1 EH/s of mining capacity, contingent on equipment selection and commissioning, currently targeted for the second half of 2026. CEO Sheldon Bennett stated, “June presented unexpected challenges with our mining infrastructure, yet we continue progressing toward relocating our operations to areas with cheaper energy. We are advancing discussions with Canadian government agencies, focusing on the Department of National Defence, amid Canada’s increased military spending with AI as a priority.

We remain encouraged by Systemic Trust’s custody client onboarding and platform expansion beyond custody. ” Grant of Stock Options and RSUs DMG granted a total of 201, 607 stock options and 1, 275, 000 restricted stock units (RSUs) to employees and directors.
