DOUBLEVIEW GOLD CORP. ACHIEVES A MAJOR BREAKTHROUGH IN SCANDIUM RECOVERY FROM COPPER PORPHYRY TAILINGS

Doubleview Gold Corp. has released positive first-phase preoptimization results from its two-year, novel scandium-focused metallurgical test program. These results confirm the technical viability of recovering high-purity scandium oxide alongside copper, gold, cobalt and other metals from the company's 100-per-cent-owned flagship Hat polymetallic deposit in Northern British Columbia.

This breakthrough development marks a global first: the successful recovery of scandium from copper porphyry flotation tailings to a scandium oxide product.

The primary objective of this extensive test program, conducted at SGS Canada Inc., was to establish a viable proprietary flow sheet enabling scandium to be included in the coming, updated mineral resource estimate and preliminary economic assessment, potentially as measured, indicated or inferred resources. The company's maiden resource estimate (July 25, 2024) highlighted a scandium potential of 300 million to 500 million tonnes grading approximately 40 parts per million Sc2O3.

"The scandium resource potential is based on the drill holes on the property drilled for July 25, 2024, maiden resource estimate for other metal content than scandium. The potential quantity and grade are conceptual in nature, there has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the target being delineated as a mineral resource."

Early metallurgical testwork demonstrated that scandium could be extracted from copper flotation tailings. Subsequently, through an innovative robust testwork program at SGS Canada Inc., it has been demonstrated that scandium in flotation tailings can be recovered to a high-purity discandium trioxide product (Sc2O3).

Key metallurgical results include:

• Primary scandium extraction (leach): 82 per cent;
• Overall scandium recovery to high-purity Sc2O3 product: 88 per cent.

Future work to advance the Hat project will focus on continuous pilot plant testing and further optimization to improve primary extraction and enhance final product purity.

Farshad Shirvani, president and chief executive officer of Doubleview, stated: "Today's results are a game-changer for the Hat project and potentially for the entire scandium industry on the world stage. World scandium supply is severely limited although there are several scandium projects currently being considered for development. Our metallurgy program shows that, at Hat, we can recover high-value scandium directly from the tailings of a standard copper flotation circuit, using acid produced from internally generated pyrite. If the Hat project advances to production, scandium could become a high-margin bonus on top of a potential world-class copper-gold-cobalt operation.

"Now that we've established the technical viability of scandium recovery, the next steps will focus on pushing extraction and overall recovery as high as possible through continued optimization and pilot-scale testing. I could not be more excited about what the future holds for Doubleview shareholders and all our stakeholders."

What is scandium?

Scandium (atomic weight 45.10, density 2.5), a close relative of the rare earth elements, possesses exceptional properties when alloyed with other metals, particularly aluminum. It is lightweight and corrosion resistant, and, as an alloy, is capable of dramatically improving strength, heat resistance and weldability without adding significant weight. When combined with aluminum, scandium forms alloys that achieve the strength of steel while maintaining the light weight of aluminum, enabling revolutionary applications in transportation, aerospace and clean energy. Scandium's scarcity, produced in limited quantities globally, primarily as a byproduct, makes it a high-value critical mineral, with prices often exceeding $5,000 per kilogram. Its applications span aerospace, defence and, increasingly, the clean energy sector, where it plays a pivotal role in advancing sustainable technologies. Global scandium resources are dominated by projects in Australia and northern Europe. Canadian deposits potentially can allow diversity of supply within a stable and mature mining jurisdiction.
