Zentek (NASDAQ:ZTEK) has completed the first phase of a ~$1.1 million Innovative Solutions Canada contract to develop a countermeasure for highly pathogenic avian influenza (HPAI) A(H5N1). The project, which began in November 2024, involves collaboration with McMaster University's Li Lab to create both prophylactic and therapeutic solutions using multivalent aptamer technology.

The development phase has successfully produced a lead candidate countermeasure that matched the performance of a monoclonal antibody positive control in recent in vitro neutralization experiments. The project is now moving to the testing phase, where the team will evaluate in vivo performance against H1N1 and the current H5N1 2.3.4.4b clade.

The initiative is supported by government testing partners including Health and Emergency Preparedness Canada (HERC) and Defence Research and Development Canada (DRDC), addressing the global avian influenza outbreak that has affected over 1,000 dairy cattle herds across 17 U.S. states.

Zentek (NASDAQ:ZTEK) has announced the completion of a Canada Revenue Agency (CRA) audit regarding the company's 2018 and 2019 renunciation of Canadian exploration expenses (CEE). The audit, completed on January 14, 2025, focused on flow-through common shares private placements that raised $4,210,000.

The CRA's reassessment for 2018 resulted in a reclassification of approximately $507,000 (16.895%) of renounced amounts, as they did not meet CEE definition requirements. This led to a Part XII.6 tax assessment of $59,693. A similar reclassification is expected for 2019, with details pending.

The company will indemnify affected subscribers within 20 business days for tax attributable to disallowed CEE renunciations, with maximum liability estimated at approximately $527,000. Subscribers affected by CRA reassessments are directed to contact fts@zentek.com for indemnification claims.
