Koonenberry IP survey identifies six priority drill targets along Sunnyside Shear Zone
Koonenberry's IP surveying maps >2km strike of Sunnyside Shear Zone at its Enmore project Survey identifies six priority drill targets with coincident gold and arsenic in soil anomalism Same survey technique expected to help unlock 30km of prospective zones across project Special Report: Fresh from defining bulk tonnage gold potential at the Sunnyside prospect, Koonenberry Gold has completed induced polarisation geophysics that identified six high-priority drill targets along the Sunnyside Shear Zone in NSW. The survey mapped the Sunnyside Shear Zone as a linear resistivity low within the granite, which is the preferred host rock to the extensive gold mineralisation intersected at Sunnyside. Koonenberry Gold (ASX:KNB) said the Sunnyside Shear Zone was interpreted to pinch and swell along its >2km strike length, potentially providing dilational sites for gold mineralisation where the structure opened up. The six drill targets are identified along first and second order structures, which are considered important fluid pathways for gold mineralisation, with coincident gold and arsenic in soil anomalism. Use of IP surveys in mapping first and second order structures is expected to help with exploration of the more than 30km of prospective shear zones at the broader Enmore project in northern NSW. It can also assist with ranking targets identified at the district scale. 'We have completed an electrical geophysical survey at Enmore, which has added to our understanding of the structures that are controlling mineralisation at Sunnyside,' KNB managing director Dan Power said. 'Extrapolating away from known mineralisation at Sunnyside we have identified several priority targets that are lined up along the Sunnyside Shear Zone. 'These occur within the preferred granite host rock and are supported by robust gold and arsenic anomalies in soil geochemistry. This data highlights prospectivity to the east of Sunnyside where we see the potential for extensions and repetitions to the gold mineralisation. 'A +2km long prospective zone is shown along the Sunnyside Shear Zone at the contact between the granite and sediments with coincident gold and arsenic in soils and high-grade rock chip results highlighting six priority drill targets which remain untested.' Survey analysis and forward plan KNB initially carried out the gradient array IP survey on a 400m by 400m area covering the main area of drilling at the Sunnyside prospect. It was designed to map any chargeable features from sulphides observed in the drilling and/or resistivity contrast to map changes in geology and alteration. This found the resistivity was mapping the shear structures, geology and other cross-cutting structures with a significant level of detail, leading the company to extend the survey towards the east before a separate survey was planned and completed at Hand in Hand. While dipole-dipole IP surveying was found to be unsuitable for drill targeting at Sunnyside, the results indicated that GAIP might be suitable for mapping first and second order structures which are considered important fluid pathways for gold. The company is planning +10,000m of drilling to follow-up on its successful maiden drilling at Sunnyside. This will test the continuity and extensions to mineralisation at Sunnyside as well as test the Sunnyside Shear Zone, particularly to the east where the company has identified a ~2km strike length of highly prospective granite associated with gold and arsenic soil anomalies. Wide-spaced, relatively shallow historical drilling in this area contained anomalous gold, adding further to the prospectivity of this zone. Additional soil sampling has also been conducted along the Borah Fault, a parallel fault to the Sunnyside Fault with encouraging results that will require drill testing.

Spark Confirms Four High-Priority Lithium Drill Targets in Brazil's Lithium Valley; 1,217 ppm Li at Macuco
Vancouver, British Columbia--(Newsfile Corp. - July 18, 2025) - Spark Energy Minerals Inc. (CSE: SPRK) (OTCID: SPARF) (FSE: 8PC) ("Spark" or the "Company") has confirmed four high-priority lithium drill targets at its flagship Arapaima Project in Brazil's Lithium Valley. This milestone marks a major step toward Spark's first-ever drill campaign in one of the most lithium-rich jurisdictions in the world. "These four drill targets reflect months of rigorous fieldwork and geochemical validation," said Eugene Hodgson, CEO and Chair. "With pegmatite swarms, strong lithium values, and immediate access, Spark is positioned for a major exploration breakthrough. We're unlocking real discovery potential in one of the world's most important battery metal jurisdictions." Highlights Four drill-ready lithium targets identified: Testa, Pedro, Robertinho/Bob, and Macuco Rock sample returns up to 1,217 ppm Li at Macuco 62 rock samples and 20 stream sediment samples collected to date in July 15 new stream sediment samples advance rare earth and gallium exploration over Caladão Granite Figure 1: A charnokite sample (ARA-CR-240) was collected for total chemical analysis (whole-rock geochemistry). To view an enhanced version of this graphic, please visit: Charnockite is a high-grade metamorphic rock formed deep in the Earth's crust under intense heat and pressure. It often hosts valuable minerals due to its complex geological history and is commonly associated with ancient, stable continental regions known for mineralization. Charnockite is a known source rock for REE (rare earth element) mineralization and is expected to guide short-term REE drill targeting. The collected sample (ARA-CR-240), shown in Figure 1, will undergo full chemical analysis to assess its potential for containing economically important element s. Drill-Ready Lithium Targets Identified Fieldwork conducted during the week of July 7–11 focused on advancing and confirming priority lithium-bearing pegmatite targets across four key areas: Água Branca – Testa Target: Stream sediment anomalies and confirmed pegmatite dikes make this a high-conviction drill target. An existing access route at the top of the hill enables rapid mobilization. Pedro Target (Toninho de Biza mine): A 1.2 km historic road has been surveyed for reopening, enabling efficient access to mapped pegmatite swarms. Córrego da Lagoa / Lorentino – Robertinho & Bob Targets: Planning is underway for initial drill holes at the Robertinho target, with potential follow-up at the adjacent Bob site. Macuco Target: A standout sample from black mica in a shallow pit returned 1,217 ppm lithium —one of the highest to date. Follow-up work confirms the area as a top-priority drill target. Caladão Granite – Advancing Rare Earth and Gallium Discovery Spark continues to expand geochemical coverage across the Caladão Granite, an intrusive unit with demonstrated potential for rare earth elements (REEs) and gallium. Fifteen new stream sediment samples were collected this week to complement earlier campaigns that returned elevated REE and gallium values in adjacent areas. Next Steps & Shareholder Catalysts Spark is actively progressing toward its first drill campaign in Brazil, with multiple targets advancing in parallel. Immediate priorities include: Finalizing access and permitting at four confirmed drill targets Completing stream sediment coverage over the REE- and Ga-rich Caladão Granite Integrating geochemical and geological data to optimize drill collar placement and prioritize short-term drill targets for lithium and REE Spark Energy Minerals is positioning itself as a key exploration player in Brazil's Lithium Valley — a globally strategic jurisdiction for future-facing metals.
