Sun Peak Drills 39.0 Metres of 1.38% Copper and 0.84% Zinc and 19.42 Metres of 1.17% Copper, 2.59% Zinc and 22.35 G/T Silver at Safra Vms Project, Saudi Arabia

VANCOUVER, BC / ACCESS Newswire / September 8, 2026 / Sun Peak Metals Corp. (TSXV:PEAK)(OTCQB:SUNPF) ("Sun Peak" or the "Company") today announced assay results from its maiden diamond drill program at the Company's 100%-owned Safra volcanogenic massive sulphide ("VMS") Project in the Kingdom of Saudi Arabia ("KSA" or "Saudi Arabia"). The initial 10-hole program totalled 1,242 metres and tested the Safra Main and Safra South targets.

All seven holes drilled at Safra Main returned mineralized intervals of disseminated to massive sulphide, confirming that the mineralized system identified at surface continues below surface and remains open at depth and along strike for follow-up testing.

The results demonstrate that Sun Peak's integrated approach of combining geological mapping and interpretation with ground gravity and ground Time Domain Electromagnetics (TDEM) surveys can successfully develop geological models and generate drill targets, providing increased confidence as the Company advances numerous additional targets across its Saudi Arabian portfolio.

Highlights

• 39.0 metres averaging 1.38% copper and 0.84% zinc, including 17.75 metres averaging 1.60% copper and 1.58% zinc in Hole SAF26DD008;

• 19.42 metres averaging 1.17% copper, 2.59% zinc and 22.35 g/t silver, including 3.0 metres averaging 3.08% copper, 11.72% zinc and 57.25 g/t silver. A second interval in the same hole returned 13.0 metres averaging 0.49% copper, 1.77% zinc, 1.64% lead, 69.17 g/t silver, and 0.61 g/t gold, including 6.0 metres averaging 0.96% copper, 3.35% zinc, 3.15% lead, 127.43 g/t silver, and 1.02 g/t gold in Hole SAF26DD005;

• Additional high-grade intersections include 8.85 metres averaging 1.32% copper and 6.51% zinc in SAF26DD001; 6.80 metres averaging 0.48% copper, 3.19% zinc, 34.81 g/t silver and 1.33 g/t gold in SAF26DD003; and 6.0 metres averaging 2.86% copper and 5.70% zinc in SAF26DD010.

"Our team is thrilled with the results of our first drill project in the Kingdom. We drilled exceptional intercepts of copper, zinc, gold and silver that remain open for further expansion," said Greg Davis, President and CEO of Sun Peak. "The results are very encouraging, and we see clear opportunities to extend the mineralized zones through follow-up drilling. The results validate the exploration process our team applied at Safra and confirms the geological model."

"We are applying this same disciplined methodology to numerous other targets across our Saudi Arabian portfolio," continued Mr. Davis. "In addition, we have numerous high-priority VMS and gold targets across our Saudi licenses, including Al Miyah, Washaq and targets generated across the Round 9 licenses. Our objective is to systematically drill-test this pipeline and pursue the potential for multiple discoveries across the portfolio."

"The initial drilling intersected broad zones of copper and zinc-rich VMS mineralization with associated gold and silver, confirming the significance of the Safra Main system. These encouraging results, combined with previous geophysics and surface work, provide a strong foundation for the next program," said Arron Albano, Exploration Manager of Sun Peak. "Importantly, the presence of significant mineralization has strengthened our interpretation of the untested gravity anomalies at Safra North and Safra East. Including Safra Main, these will be the next high-priority targets for follow-up exploration programs. The geological and geophysical signatures and style of mineralization observed at Safra share important characteristics with other significant VMS deposits of the Arabian-Nubian Shield."

Safra Drill Results

The maiden drill program comprised 10 diamond drill holes totaling 1,242 metres (Figures 1 and 2). At Safra Main seven holes tested coincident geological, geochemical and geophysical targets developed through surface mapping and sampling, trenching, gravity and TDEM surveys. Three holes tested conductive TDEM targets at Safra South, located approximately 1.5 kilometres south of Safra Main (Figure 1). Substantial portions of the mineralized trends, geophysical targets and their depth extent remain untested.

The Safra Main Zone remains open for expansion both to the north toward the Safra North target and south along strike, as well as at depth (Figures 3, 4, and 5). Importantly, additional strong and currently untested gravity anomalies, including Safra North, occur along the projected strike of the mineralized system providing compelling targets for follow-up exploration and drilling (Figure 1). These anomalies highlight the potential for the Safra Main mineralized system to extend beyond the limits tested by drilling to date and/or for additional zones of sulphide mineralization to occur along the broader prospective trend.

The Safra East Zone, a parallel VMS trend located approximately 1.5 km east of Safra Main, remains untested by diamond drilling. VMS-related, gossanous exhalite grab samples collected from the zone have returned up to 1.38% Cu, with additional samples returning 1.08% Cu and 0.22% Cu. Importantly, the surface mineralization is spatially associated with a strong gravity anomaly, providing a compelling coincident geochemical and geophysical target. The combination of copper-rich VMS-style mineralization at surface and the underlying gravity response highlights Safra East as a high-priority target for future drill testing and provides additional exploration upside beyond the currently drilled Safra Main Zone.

The principal mineralized intervals with assays are summarized in Table 1 and shown on Figures 3 to 5. Reported intervals are core lengths unless otherwise indicated.
