Kali Metals has identified nine new gold targets across a 118-square-kilometer area at its Marble Bar project in Western Australia, expanding its exploration footprint ahead of a field program scheduled to begin in mid-October 2026. The new zones, designated as areas A through I, extend significantly beyond the four previously drilled occurrences at the site, boersennews.de reported.
The fresh targets were delineated using soil geochemistry and high-resolution drone imagery gathered during the September 2026 quarter, according to boersennews.de. Previous diamond drilling at those established locations returned high-grade intercepts, including 2.6 meters grading 10.8 grams of gold per ton from an 8.7-meter depth in hole MBDD004, and 1.8 meters grading 7.4 grams of gold per ton from the surface in MBDD002.
Targeting the Warrawoona Group at the Project Western Margin
Particular focus is directed toward the western perimeter of the tenement holdings.
Edgar batholith. The terrain features a complex assemblage of granitoids, basalts, felsic volcanics, and sediments. While the close geological proximity of known gold occurrences acts as a primary vector for exploration, the company notes that geographical nearness alone does not guarantee a commercially viable deposit.
Historical Drill Results Set Comparative Benchmarks
Alongside the diamond core assays, the company references historical reverse circulation drilling data from earlier phases to provide context for potential structural continuities. Phase II drilling produced intercepts such as 3 meters grading 3.6 grams of gold per ton from 41 meters depth in hole MBRC081, and 5 meters grading 1.0 gram of gold per ton from the same depth in MBRC082. Earlier Phase I drilling yielded 5 meters grading 2.3 grams of gold per ton from the surface in MBRC001, alongside 4 meters grading 3.2 grams of gold per ton from the surface in MBRC003.
These historical figures originate strictly from the four previously evaluated prospects rather than the newly minted exploration zones. The upcoming field campaigns aim to determine whether these mineralized gold structures extend into the newly outlined 118-square-kilometer expanse.
Helicopter-Supported Fieldwork Scheduled for October
A helicopter-assisted reconnaissance program will launch in mid-October 2026 to execute systematic mapping, outcrop checks, and rock chip sampling across all nine targets within a ten-day window, according to boersennews.de. Concurrently, technical teams will process data from a project-wide hyperspectral survey. This remote-sensing technique reads light spectra to identify specific mineral signatures, helping geologists refine target boundaries and assess alteration halos.
Cultural heritage surveys are also running in parallel across selected tracts, including extensions around the previously drilled prospects. The integration of hyperspectral maps, surface geochemistry, and field observations will establish a prioritized ranking system to determine which specific targets warrant subsequent phase-testing through deep drilling.
Frequently Asked Questions About the Marble Bar Exploration
Where is the Marble Bar gold project located?
The project spans an area situated roughly 10 to 15 kilometers east of Marble Bar in Western Australia, covering approximately 118 square kilometers along the western edge of the Mt. Edgar batholith.
What methods were used to identify the nine new targets?
Kali Metals used soil geochemistry—measuring low-level gold concentrations in the dirt—combined with high-resolution drone imagery gathered during the September 2026 quarter to map out areas A through I.
When will the next phase of fieldwork begin?
A helicopter-supported mapping and rock-sampling program is slated to kick off in mid-October 2026, designed to cover all nine newly identified zones over an intensive ten-day schedule.
