TRIMERA METALS PROVIDES UPDATE ON TAHLO LAKE EXPLORATION PROGRAM AND ENGAGES MCS MARKET COMMUNICATION SERVICE GMBH FOR MARKETING CAMPAIGN

Trimera Metals Corp. has provided an update on proposed exploration activities for its 1,692.22-hectare Tahlo Lake porphyry copper-molybdenum-gold property, located in north-central British Columbia. The company has engaged MCS Market Communication Service GmbH to conduct a six-month digital marketing campaign in support of the company's investor relations efforts.

Tahlo Lake exploration program

The Tahlo Lake property is located approximately 11 kilometres to the northeast of American Eagle Gold Corp.'s NAK project, where drilling has identified numerous long high-grade intervals of copper-gold mineralization. The Tahlo Lake property is within a prospective belt of rocks known as the Babine porphyry copper belt. This belt, measuring roughly 20 kilometres by 80 kilometres on the east side of Babine Lake, hosts many copper-rich mineral deposits at varying stages of development, from notable occurrences to developed prospects to past-producing mines. The Tahlo Lake property is at the northern end of this prospective belt of rocks.

Given that there has been little historical exploration on the property due to extensive surficial glacial deposits that cover much of the project area, initial exploration activities are expected to focus on low-cost remote geological tools, such as prospecting, mapping, rock sampling and basal till sampling. Basal till sampling is an effective exploration technique that could identify mineralization in the underlying bedrock. In addition to boots-on-the-ground exploration, the company intends to carry out an induced polarization geophysical survey to identify subsurface disseminated sulphides. Other proposed work will include more detailed interpretation of last year's Z-axis tipper electromagnetic (ZTEM) and light detection and ranging (lidar) surveys. Company management is currently formulating the details of the proposed summer exploration program, which is expected to be completed by the end of the current summer field season. The company is to provide further details on the timing and the budget for this program within the next few weeks.

Patrick Donnelly, chief executive officer of Trimera, states: "Preparations are well under way for our inaugural field season at the Tahlo Lake project, which is within the emerging Babine porphyry belt. Given the success of our neighbour, American Eagle, I am excited to finally see us kick off exploration activities at our project, which has many geological features like that at the NAK project. I look forward to seeing the results from our summer field program."
