ROCKEX MINING PROVIDES CORPORATE UPDATE - POSITIONED FOR ONTARIO’S

ELECTRIC ARC FURNACE TRANSITION AND DEMAND FOR HIGH-QUALITY IRON UNITS

February 18, 2026 – Thunder Bay, Ontario - Rockex Mining Corporation (“Rockex” or the “Corporation”)

(CSE: RXM) is pleased to provide a corporate update as it believes global market trends, evolving

steelmaking requirements and government priorities around domestic supply chains and economic

resilience are creating a more constructive backdrop for the C orporation’s 100% owned Lake St. Joseph

Iron Project in northwestern Ontario. With the project at the preliminary economic assessment ( “PEA”)

stage, Rockex views this period as an opportune time to re -engage potential strategic partners and

stakeholders to assess interest on next -step de-risking work required to advance a potential pathway to

project development.

“We invite interest from strategic partners, end users and other stakeholders aligned with advancing

domestic iron units and strengthening Canadian industrial supply chains ,” said Pierre Gagné, Chief

Executive Officer of Rockex . “In light of government focus on national security interests, w e believe that

the quality, size and location of the Lake St. Joseph Iron Project make it an attractive opportunity to help to

address those interests.”

The Project

Rockex’s Lake St. Joseph Iron Project hosts a large hematite/magnetite resource that the Corporation

believes could be developed into a source of high-quality iron units such as hot briquetted iron (“HBI”). HBI

can complement scrap-based electric arc furnace (“EAF”) steelmaking by supporting consistent chemistry

and low impurities—an increasingly important consideration as Canadian EAF capacity expands, including

at Ontario facilities such as Algoma Steel in Sault Ste Marie.

Project PEA Summary

The 100%-owned Lake St. Joseph Iron P roject includes an Indicated Mineral Resource of 1.287 billion

tonnes at 28.39% iron (Fe), plus an Inferred Mineral Resource of 108 million tonnes at 31.03% Fe, at Eagle

Island in northwestern Ontario. The Corporation’s 2015 updated PEA was prepared by CIMA+ and

evaluated the potential for production of approximately 4.3 million tonnes per year of HBI over a 30 -year

mine life. The 2015 PEA reported a pre-tax NPV of approximately $9.42 billion at a 6% discount rate (post-

tax NPV of approximately $6.85 billion at a 6% discount rate) , based on an HBI price assumption of

US$350/t and other assumptions applicable at that time (see the Corporation’s news release on October

27, 2015, and related Preliminary Economic Assessment filed at that time on the Corporation’s SEDAR

profile and currently available on the Corporation’s profile at www.sedarplus.ca). The Corporation’s 2015

PEA was prepared in 2015 based on commodity prices, costs, sales, revenues and other assumptions and

projections which were current at that time, many of which have changed over the intervening years and

may make the analysis in some respects outdated. Readers should refer to the Co rporation’s technical

disclosure and its other filings on its SEDARplus profile for full assumptions, sensitivities and risk factors

associated with the 2015 PEA and with the Corporation’s ongoing business and activities.
