ASX Announcement

Target Generation Drilling Underway on Emerging Bunjarra Gold Trend

Highlights

• ➢ Infill aircore drilling has commenced at Bunjarra to follow up recent exciting aircore hits up to 10m @ 3.61g/t Au[1] in composite sampling.

• ➢ Bunjarra hosts a variety of strong bedrock gold targets, with gold anomalism identified in multiple geological locations below a blanket of shallow transported cover.

• ➢ Drilling will tighten traverse spacing along an evolving 2km mineralised trend in the southern part of the Licence and will allow targeting to be refined for a maiden Reverse Circulation (RC) program to test fresh-rock gold targets.

• ➢ Results are awaited from first-pass aircore drilling over promising soil-covered lithostructural targets at Edjudina Range and Cosmo, and additional 1m re-sampling at Bunjarra and Box Soak. Samples are at the laboratory and results will be reported when available.

• ➢ Site works also underway ahead of drilling at the advanced Bluetooth Gold Prospect, where a program of shallow RC drill holes will follow-up historical drill intercepts[2] including 12m @ 1.31g/t Au to end of hole (EOH), 15m @ 0.95g/t Au, 8m @ 1.66g/t Au and 2m @ 5.07g/t Au EOH.

• ➢ The Company continues to pursue its strategy to bring forward new, commercially relevant gold prospects in this highly prospective and productive sector of WA’s Eastern Goldfields.

Solstice Minerals’ Chief Executive Officer and Managing Director, Mr Nick Castleden, said:

“Solstice continues its search for stand-alone scale gold mineralisation on its extensive Yarri Project landholdings. Bunjarra has risen to the top of our greenfield hit-list following recent exploration success that included composite aircore results to 10m @ 3.61g/t Au , supporting an adjacent hit of 2m @ 1.85g/t Au[3] . Bunjarra is a classic Eastern Yilgarn gold target, with strong indications of gold in a compelling ‘buried’ structural setting. The field team have worked hard to re-start aircore drilling in short order and this campaign will guide maiden RC drilling to test the fresh rock geology below a leached weathering profile.”

Bunjarra Follow-up Aircore

Solstice Minerals Limited (ASX: SLS, Solstice , the Company ) is pleased to advise that aircore drilling has re-commenced at the Company’s emerging Bunjarra Project in WA. This round of drilling is designed to tighten line spacing to a density that will allow optimal design for maiden RC drill-testing.

In the southern part of the Licence, where a >2km trend of gold anomalism is taking shape , infill aircore traverses will straddle existing wide-spaced drill lines (between 200m and 500m apart) and followup a recent result of 10m @ 3.61g/t Au (in 5m composite samples) in BJWAC066 (supported by 2m @ 1.85g/t Au in adjoining BJWAC002) and 1m @ 4.49g/t Au in BJWAC041[4] , located 800m to the north ( Figure 1 ).

Additional drilling will be carried out around strong anomalism in historical drilling, including 1m @ 14.8g/t Au[5] adjacent to a local felsic intrusive in the north-west of the Licence, and in other places where past drilling has returned base-of-oxidation gold anomalism in consecutive drillholes.

The combined gold results to date at Bunjarra highlight the potential for mineralised bedrock structures in multiple locations, with widespread >0.10g/t Au anomalism recorded in drillholes over many

kilometres of strike. Gold mineralisation typically sits at the interface between oxidised and unoxidised bedrock, a typical Goldfields geochemical setting and an indicator of proximal bedrock gold mineralisation.

Bunjarra lies approximately 70km northwest of Northern Star’s (ASX: NST) Porphyry mining centre, 20km southeast of Saturn Metals’ (ASX: STN) Apollo Hill gold deposit and along strike from a significant gold drill-out to the south ( Figure 2 ). The Licence is covered by a blanket of shallow transported alluvial material that has limited the effectiveness of previous exploration.

Reconnaissance Aircore Programs – Edjudina Range and Cosmo

Results are awaited from first-pass aircore drilling completed over promising soil-covered litho-structural targets at Edjudina Range and Cosmo ( Figure 3 ). The targets at Edjudina Range are below shallow

transported cover and along strike from the Company’s advanced Statesman Well Project , while drilling at Cosmo tested below a local alluvial channel that obscures underlying prospective geology.

The Cosmo target lies immediately north of the Hobbes tenement, which was recently sold to a subsidiary of Northern Star Resources Limited (ASX: NST) for $12.5M[6] .

Additional 1m resampling of mineralised composite samples at Bunjarra and Box Soak has also been carried out. All samples have been submitted for analysis and results will be reported when available.

Bluetooth RC Drilling

On-ground preparations continue for first-stage RC drilling at the Company’s advanced Bluetooth Gold Prospect on the Box Soak tenement group.

The Prospect has been shallowly drilled in the 1990’s and hosts historical drill intercepts that include 12m @ 1.31g/t Au to EOH , 15m @ 0.95g/t Au , 8m @ 1.66g/t Au and 2m @ 5.07g/t Au EOH that report to zones of silicified chert, ironstone and quartz veining extending over more than 1km of strike ( Figure 4 ). Historical RC drilling is at 100m line-spacing, and in places with only one effective hole per drill section.

Approximately 20 shallow RC holes have been designed ( Figure 4 ). Drilling will improve the understanding of geological controls at this Prospect and results will guide future infill, step-out and extensional exploration drilling. Drilling is planned to commence in the December 2024 Quarter once the current program of aircore drilling at Bunjarra has been completed.

Forward Planning

The Company continues to work-up further quality greenfield gold targets on its 1,730 square kilometres of Yarri Project tenure, with a focus on testing targets that offer potential for ‘stand-alone’ scale. The current aircore drilling campaign at Yarri is likely to continue through the remainder of 2024, with the aim of bringing forward more new targets for RC drilling.

About the Yarri Project

The Company’s Yarri landholding is close to existing infrastructure, with dedicated haul roads and ore processing facilities typically within 50–100km. In this infrastructure-rich area, even modest scale gold mineralisation has potential to be commercialised, as underscored by the sale of the Company’s Hobbes tenement.

With an extensive belt-scale footprint in WA’s Eastern Goldfields, the Company continues to offer strong leverage to gold exploration success. A robust cash position provides Solstice with excellent flexibility to expand its asset base beyond its current Projects, and the Company continues to review a number of compelling business development opportunities.
