About this update from Noble Plains Uranium Corp

[{"type":"text","content":" Highlights Maiden resource estimate prepared in accordance with NI 43-101 standards of 5.32 million pounds Indicated and 1.04 million pounds Inferred - delivered just eight months after closing the Project acquisition. Beat the upper limit of the prior Exploration Target by every key metric: a 30% increase in grade and a 40% increase in GT (grade × thickness) versus the upper limit of the Exploration Target over the mineralized zone in WWC's August 2025 Duck Creek Technical Report. Only half the story told so far: the 2025 drill program covered just 2.5 miles of an approximately 5.25-mile mineralized trend, leaving roughly 2.75 miles of largely untested strike on the Company's expanded claim position.

The estimate, prepared by WWC Engineering (\"WWC\") of Sheridan, Wyoming, follows the Company's successful drilling campaign and represents a foundational milestone for Noble Plains. \"Today's resource announcement is a defining moment for Noble Plains and, importantly, one we've delivered in well under a year from the day we closed on Duck Creek. Our thesis was simple: take a historically drilled, brownfield uranium asset in one of the best uranium addresses in North America, execute with discipline and efficiency to convert it into compliant pounds.
