Star Metro - Eagle Plains and Tana Resources Execute Option Agreement for the MPW Copper-Gold Project, British Columbia

Key highlights include:

• Historical trenching returned 1.12% Cu over 35m, including 7.12% Cu over 5m ¹

• Historic exploration has documented

  • multiple mineralized intrusions similar in nature to the Mount Polley Intrusive Complex (MPIC) ²

  • coincident geophysical and geochemical anomalies that support the presence of additional prospective intrusions ³

• Exploration by Eagle Plains has located down-ice basal till gold grain counts indicative of potential proximal sources ⁴

Chuck Downie, President and CEO of Eagle Plains commented "Grass roots fieldwork by Eagle Plains and past operators at MPW has identified many of the geological indicators associated with porphyry and epithermal mineralizing systems and we look forward to working with the Tana team to advance the Project."

"We are excited to add the Mount Polley West project to the Tana portfolio and work with the Eagle Plains, one of the top project generators," commented Tana CEO Vic Koraijan. "The historic compilation in combination with the recent work by Eagle Plains has identified excellent porphyry and epithermal targets in a known mineral rich belt," he added.

To exercise the Option, Tana must make a series of cash payments and share issuances to Eagle Plains and fund exploration expenditures on the Project. These payments, share issuance and expenditures are separated into two phases, with the First Option entitling Tana to acquire a 60% interest in the Project by paying CA$250,000, issuing an aggregate of 2,750,000 common shares to EPL and funding CA$3,000,000 in exploration expenditures on the Project by over a four-year term, including $75,000 in expenditures in 2025. Pursuant to the Second Option (if elected by Tana), Tana may acquire an additional 15% interest in the Project (for a 75% total interest) by notifying Eagle Plains of its intent to increase its interest to 75%, and by completing a bankable feasibility-level study on the Property prior to December 31, 2031.

If either the First Option or the Second Option is exercised, a 2% smelter return royalty will be granted to the Eagle Plains over part of the property, 1% of which may be repurchased for CA$1,000,000.

Eagle Plains will serve as Operator under the terms of Option and will reserve the right to use TerraLogic Exploration Inc. as geoscience consultant. Following the exercise of either the First Option or the Second Option, Tana and Eagle Plains shall then form a 60/40 or 75/25 joint venture ("JV") to further explore and develop the Property.

Some of the above results were taken directly from MINFILE descriptions and assessment reports (ARIS) filed with the BC government. Management cautions that historical results were collected and reported by past operators and have not been verified nor confirmed by a Qualified Person but form a basis for ongoing work on the subject properties. Management cautions that past results or discoveries on proximate land are not necessarily indicative of the results that may be achieved on the subject properties.

The Mount Polley West property lies in the Quesnel Trough and is underlain by the Triassic Nicola Group volcanics and volcaniclastics intruded by coeval and younger small stocks, plugs and dykes of syenitic to monzodioritic composition, a setting similar to the Mount Polley Mine approximately 5 kilometres to the east. In addition, 10 documented BC MINFILE mineral occurrences lie within the property boundaries, primarily copper showings.
