Kingfisher Metals Confirms Early Jurassic Porphyry Mineralization Across Hank-Mary District, a Fertile Window Between Mitchell Cu-Au and Brucejack Au-Ag Deposits

Multiple U-Pb and Re-Os dates between 190-186 Ma establish that the Hank-Mary district formed within a minimum 4-million-year period during a key regional gold-rich mineralization window. The closest age porphyry deposit is Mitchell (KSM), the largest Cu-Au porphyry deposit in Canada and the closest age epithermal deposit is Brucejack Au-Ag.

VANCOUVER, BC / ACCESS Newswire / April 28, 2026 / Kingfisher Metals Corp. (TSXV:KFR)(FSE:970)(OTCQB:KGFMF) ("Kingfisher" or the "Company") is pleased to announce new U-Pb zircon and Re-Os molybdenum geochronology results from the Hank-Mary district on its 933 km² HWY 37 Project, Golden Triangle, British Columbia. The initial results demonstrate that magmatic-hydrothermal activity across the Hank-Mary district is part of highly fertile and gold-rich mineralizing time in the region. These dates overlap with established ages for the Mitchell porphyry deposit at the nearby KSM project, the largest undeveloped Cu-Au porphyry deposit in Canada and is close to the age of the Brucejack epithermal Au-Ag deposit (Table 1 & Figure 1 - 3).

Key Highlights:

• Similar age as Mitchell Cu-Au porphyry deposit: Porphyry mineralization at Hank, Williams & Mary (~190-186 Ma) overlaps with the Mitchell deposit (~196-189 Ma).

• Similar timing to Brucejack Au-Ag epithermal deposit: Epithermal gold mineralization at Hank (~188-184 Ma) ties closely with the Brucejack deposit (~184-183 Ma).

• One large system: Ages from Hank, Mary, and Williams all fall within the same range, suggesting a single, large mineralizing system that defines the district.

• Geological age as a fertility indicator: These ages match the Early Jurassic Texas Creek intrusive suite of rocks, known for hosting major porphyry deposits in the Golden Triangle.

Dustin Perry, CEO and President of Kingfisher, states, "These initial geochronology results validate our exploration model and confirm our belief that the Hank-Mary district represents a large, fertile porphyry system. The confirmation that mineralization across Hank, Mary, and Williams falls within the same Early Jurassic window as the Mitchell and Brucejack deposits highlights strong parallels to two of the most significant gold-rich systems in Canada."

Geochronology Results

Two complementary dating methods applied across the Hank district from three studies:

U-Pb zircon geochronology constrains the crystallization age of host intrusions, the timing of magma emplacement, and is performed on zircon mineral separates from intrusive rock samples.

Re-Os molybdenite geochronology directly dates ore-forming hydrothermal events by measuring the radioactive decay of rhenium to osmium in molybdenite (MoS₂), a common porphyry mineral. Molybdenite often precipitates from later-stage hydrothermal fluids during mineralization, Re-Os ages are interpreted to reflect the youngest ages of porphyry mineralization. The results in Table 1 present new data from the British Columbia Geological Survey research by Roddy Campbell presented at Rock Talk 2026², new data from Kingfisher Metals and includes one previous result from the Williams deposit.

Interpretation: District and timing relative to the Mitchell and Brucejack deposits

District Scale

The similar-age results across Hank, Mary, and Williams (~190-186 Ma) are consistent with a district-scale magmatic centre capable of generating multiple porphyry deposits, analogous to the multi-phase, multi-centre architecture of the world's largest porphyry districts.

Mitchell

The Mitchell deposit (KSM project) has an interpreted span of mineralization ~192 to 190 Ma with youngest magmatism ending around 189 Ma⁴. Early results from the Hank district indicate porphyry mineralization is between 190 and 186 Ma, with overlap in age with the Mitchell porphyry. Mitchell is the closest in age porphyry system in the region, located approximately 75 km from Hank, and is Canada's largest undeveloped Cu-Au deposit. This time window is considered highly prospective.

Brucejack

Epithermal gold at Hank emplaced after ~188 and before 184 Ma⁵. This timing ties closely with the nearby Brucejack deposit, where epithermal Au - veins are formed between 184-183 Ma⁶. Brucejack is the only known system in the region with this timing, making it a strong analogue for Hank. However, more work is needed to better define the exact age of gold mineralization at Hank.

Background: Geological Age and Porphyry Fertility

New and recently published geochronology places the Hank district in one of the most fertile periods in BC, between Mitchell porphyry (KSM) and Brucejack epithermal Au-Ag deposits. Within these prospective time windows in the region, multiple deposits can be mineralized simultaneously across a large district that is fed by a common district-scale magmatic hydrothermal system.

Geological age is a powerful predictor of porphyry copper-gold and epithermal Au-Ag fertility. In the Golden Triangle of northwestern British Columbia, some of the most significant Cu-Au porphyry deposits and epithermal Au-Ag deposits which include the world-class KSM system and nearby Brucejack deposit are genetically linked to Early Jurassic (~196-185 Ma) Texas Creek magmatism (Figure 3).
