About MetalQuest Mining

MetalQuest Mining (MQM) owns 100% of Lac Otelnuk and is working to develop one of the largest Iron

projects in North America. The Lac Otelnuk Iron Project is located in Quebec’s Labrador Trough and is

approximately 165 km by air northwest of the Town of Schefferville, and 1200 km northeast of Montreal

by air. The Company has recently acquired a portion of the underlying net smelter return (NSR)

royalty on the Project, https://metalquestmining.com/news/metalquest-mining-amends-royalty-on-its-

lac-otelnuk-iron-project-in-quebec/.

The Quebec government has transferred 100% of the claims into MQM’s name and management is

accumulating a vast amount of technical data as approximately $120 million has been expended on the

project to date. Going forward, one of our primary objectives will be to continue to work with Naskapi First

Nation of Kawawachikamach with whom we have an Exploration and Pre -Development Agreement as of

November 2023.

A Gap Study Analysis was completed a s of February 18 th, 2026, by AtkinsRéalis, a global engineering

leader and lead author of the 2015 feasibility study, provided a clear framework for the Project’s next stage

of advancement. Importantly, the review did not identify any issues that would preclude continued

advancement of the Project. MetalQuest is advancing Lac Otelnuk through a phased approach focused on

technical validation, modernization opportunities, infrastructure and logistics planning, ESG and permitting

progress, and updated economic evaluation, with the goal of creating long-term value for shareholders and

stakeholders.

On December 3rd, 2025, MetalQuest Mining (MQM) announced the acquisition of the ROF-1 Project, a

critical minerals land package in Ontario’s Ring of Fire totaling 1,034 claim s (~20,800 hectares, ~52,000

acres). The Ring of Fire is one of Canada’s most important emerging critical minerals districts,

supported by growing infrastructure and government attention as the region advances toward

potential development. ROF-1 Project is located approximately 10 km from major nearby deposits and

has identified exploration potential for VMS -style mineralization and multiple untested target corridors

based on historic work and technical review. https://metalquestmining.com/news/metalquest-secures-

The previously announced acquisition of the Fishhook Polymetallic Project represents MetalQuest’s

second step in building a broader multi-project Ring of Fire strategy, with the Company continuing

to review additional opportunities in the region. https://metalquestmining.com/news/metalquest-

New Age Metals Inc., a significant shareholder of MetalQuest Mining Inc. with approximately 14.39%,

has recently advanced into the Ring of Fire through the acquisition of new exploration properties,

reflecting increasing exploration momentum within the district. New Age Metals’ activities are

independent of MetalQuest’s operations.

New Age Metals is focused on the discovery and advancement of platinum group metals and other critical

minerals projects in North America and has identified the Ring of Fire as a strategic area for long -term

growth. The expansion of its exploration portfol io within this emerging district highlights continued

industry interest in early -stage, district -scale opportunities supported by improving infrastructure,

government engagement, and regional exploration activity.

With the acquisition of the Fishhook Polymetallic Project in the Ring of Fire, on the January 23 rd,

2026 New Age Metals Inc. and MetalQuest Mining Inc. have assembled approximately 62,800

hectares (~155,200 acres), consisting of 3,067 mining claims, subject to a 1.0% NSR with a 0.5%

buyback, forming a portfolio of early -stage exploration ground considered pro spective for critical

minerals. The companies will continue to evaluate further acquisitions in the district.

MetalQuest believes that the alignment of shareholder interest and regional exploration focus further

supports the Company’s strategy of disciplined land acquisition and systematic exploration within

the Ring of Fire.

MetalQuest Mining also recently acquired the West Cameron Gold Project located in the Kenora Mining

District of Northwestern Ontario. The Project is situated along the same regional structural corridor that

hosts the Cameron Lake Gold Deposit and is consid ered prospective for structurally controlled gold

mineralization. The Company is currently reviewing historical exploration data and planning follow -up

exploration programs designed to advance and evaluate the Project’s discovery potential.

The initial phase of work, planned for Winter/Spring 2026, at the recently acquired Superior Iron Project

will comprise systematic ground truthing, detailed geophysical surveys, and comprehensive environmental

baseline studies. These programs are designed to enhance the geological model, refine the understanding

of mineralized zones, and delineate high -priority drill targets to support the next stage of exploration and

project development.
