The Fort Worth Press - Eagle Plains and Sun Summit Make Greenfields Discovery at the Orbit Project, Toodoggone District, BC.

Sample Highlights

About the Orbit Project

The core area that makes up the Orbit Property was identified through the advanced interpretation of remote sensing data originally collected to evaluate the company's Theory Project, located 14 kms to the west and currently under option to Sun Summit. Deliverables provided by EarthDaily Analytics, identified a large area to the east of the Theory Project with hydrothermal alteration likely associated with minerals such as white mica, sericite and illite, typical indicators of porphyry mineralization. The 2025 program prospected less than 5% of the anomaly area. Several samples have been sent for petrographic analysis to Precision Petrographics of Langley, BC, with results pending.

Highlights

Strategic, Low-Cost Acquisition: Mineral rights were acquired by staking through Mineral Titles Online and issued under the new BC Mineral Claims Consultation Framework (MCCF). The Orbit acquisition makes Eagle Plains a significant rights holder in the Toodoggone District with combined ownership and Net Smelter Royalty (NSR) interests in over 17,000 hectares.

Unexplored: Within the claim boundary there are no documented Assessment Reports filed with the BC Government (ARIS) and no MinFile occurrences, with the closest known mineral occurrence from the Calypso Zone being 8 kms away. Management believes that the absence of historical exploration may be due, in part, to a lack of geophysical and geochemical anomalies. At a regional scale, publicly available geophysical data does not show significant magnetic anomalism typical to porphyry deposits of the region. Similarly, the Regional Geochemical Survey (RGS) database does not exhibit strong anomalies in the tributaries draining the property. For these reasons it is probable that the 2025 program is the first ever geologic investigation of the property.

Tier-1 Geology

The Orbit Project straddles the Quesnellia and Stikinia terranes, host to many of BC's producing and past producing porphyry deposits, and is underlain by prospective Early Jurassic granodioritic rocks of the Pitman Batholith in fault contact to the west with Lower to Middle Jurassic sedimentary and volcanic rocks of the Hazelton Group of Stikine terrane. Available geologic data from the BCGS currently exists at a regional scale only and continued field work will work toward refining a property scale geologic map.

Prominent Exploration District: The Toodoggone is regarded as a highly prospective, deposit-rich, under explored geologic region in north-central BC. It's best known for the past-producing Kemess Mine currently owned by Centerra Gold Inc. ("Centerra"). Centerra recently announced a positive mineral resource update and PEA on the Kemess Main, South, Underground and East Deposits with average grades of 0.39 g/t Au and 0.18% Cu ⁽¹⁾. The district has recently attracted investment from other senior mining companies including Freeport-McMoRan who is now 60% owner and operator of the Joy Project, originally optioned from Amarc Resources, after spending over $35 million in exploration ⁽²⁾. Significant exploration success at the Joy Project includes the recent discoveries of the Aurora (271m of 0.98 g/t Au, 0.25% Cu, and 1.93 g/t Ag) and Twin Deposits (300m of 0.51 g/t Au, 0.23% Cu and 0.5 g/t Ag) in 2024 and 2025 respectively ^(3,4). Another senior producer, AngloGold Ashanti, recently invested >$38 million into Thesis Gold and Silver Inc. to fund activities related to the Lawyers-Ranch gold-silver project ⁽⁵⁾.

A formal Agreement has been reached with Sun Summit whereby a definitive Joint Venture (JV) will be formed by December 31, 2026 to facilitate continued exploration on the property. Eagle Plains has been named the operator and ownership will initially be Sun Summit (51%) and Eagle Plains (49%). Planning is underway for a follow-up program in 2026 in conjunction with both the Theory and JD projects.

"The identification of widespread mineralization and alteration at Orbit have us excited to continue exploration this summer.", commented Jesse Campbell, Vice President of Exploration for Eagle Plains. "The traverse that found Calypso ended in mineralization and there are high priority targets that have yet to be prospected. We're also encouraged that the tenor of mineralization is consistent with several of the known, bulk tonnage deposits of the region. 2025 was an exceptional year for Eagle Plains with the discoveries of the Saboteur Zone at the Theory Project and the Calypso Zone at Orbit. In this modern exploration era, it's becoming rarer to make a significant grassroots discovery so we are very proud of our team to do it twice in just a single season.".

Quality Assurance and Quality Control

Rock samples collected during the 2025 surface program were submitted to ALS Geochemistry in North Vancouver, BC - an ISO/IEC 17025-accredited laboratory. Samples were sealed in the field, stored securely, and transported by Terralogic personnel to maintain chain of custody.

Analytical methods for rocks included full multi-element characterization by four acid digestion with ICP finish (ALS method ME-MS61). Gold was analyzed by 30 g fire assay with AAS finish (ALS method Au AA23). Samples returning >10 g/t Au were re-assayed using fire assay with gravimetric finish (ALS method Au GRA21). Due to the small sample size and brief duration of the project there were no field duplicates or Certified Reference Material standards introduced in the field. ALS preformed internal QA/QC checks including duplicates and standards. There were no significant exceedances noted by ALS.

On October 2, 2024, Eagle Plains announced the formation of a separate division within the Company that will give Eagle Plains' shareholders direct exposure to strategic opportunities in Canadian green energy transition. As a wholly owned subsidiary of Eagle Plains, Osprey Power Inc. ("OP") will focus on identifying and advancing innovative and diverse clean energy project portfolios in target markets throughout Canada, with an initial focus on Western Canada.

Eagle Plains' core business is acquiring grassroots critical- and precious-metal exploration properties. The Company is committed to steadily enhancing shareholder value by advancing our diverse portfolio of projects toward discovery through collaborative partnerships and development of a highly experienced technical team.

Expenditures from 2010-2025 on Eagle Plains-related projects exceed $41M, the majority of which was funded by third-party partners. This exploration work resulted in approximately 50,000m of diamond-drilling and extensive ground-based exploration work facilitating the advancement of numerous projects at various stages of development.

Throughout the exploration process, our mission is to help maintain prosperous communities by exploring for and discovering resource opportunities while building lasting relationships through honest and respectful business practices.
