Kali Metals Uncovers 19.2 g/t High-Grade Gold at Marble Bar

High-Grade Gold Discovery: Kali Metals Uncovers 19.2 g/t Gold at Marble Bar Project

Kali Metals Limited (ASX: KM1) has announced exceptional rock chip sampling results from its Marble Bar Gold Project in Western Australia's Pilbara region, with assays revealing gold grades of up to 19.2 g/t and a cumulative 1.4km strike length of gold-bearing outcrop.

Impressive Gold Grades Confirm Significant Discovery Potential

Recent exploration at Kali's Marble Bar Project has yielded remarkable high-grade gold assays from a comprehensive rock chip sampling program conducted between March and April 2025. A total of 276 rock chip samples were collected, revealing multiple high-grade results including:

The gold mineralisation was identified across two key prospects:

• Tiger Gold Prospect: Approximately 1.1km strike length mapped with 37 rock chip samples taken, yielding up to 19.2 g/t gold with an average grade of 2.3 g/t Au (using a 10 g/t top-cut)

• Sherman Gold Prospect: Located 2km east of Tiger, with strike length extended to approximately 300m and 9 rock chip samples yielding up to 6.6 g/t gold with an average grade of 2.4 g/t Au

"Our extensive rock-chip sampling campaign continues to identify significant gold potential at our Marble Bar Project in the Pilbara, with the latest results building on the positive soil sampling results announced earlier this year. The recent assays have returned exceptional results, including over 19 g/t gold and gold mineralisation outcrop over a cumulative length of 1.4km. With no prior drilling along this exciting, newly-identified, mineralised trend, we believe there is strong potential to discover a previously unknown gold system." – Paul Adams, Managing Director of Kali Metals

Understanding Rock Chip Sampling: What Investors Should Know

Rock chip sampling is an early-stage exploration technique that provides geologists with initial indicators of mineralisation potential. These "point samples" are collected directly from outcrops and provide a snapshot of mineral content at specific locations.

While rock chip samples cannot determine the overall grade or continuity of mineralisation (which requires drilling), high-grade results like those obtained at Marble Bar are significant because they:

1. Confirm the presence of gold in the system
2. Help geologists identify mineralised trends for follow-up exploration
3. Provide valuable information about the style and controls of mineralisation

Importantly, the gold mineralisation at Marble Bar is hosted within a quartz-rich potassic-altered zone in granite, up to 30m wide in outcrop (~10m true thickness). This geological setting provides valuable vectors for future exploration.

Strategic Project Location and Geological Setting

The Marble Bar Project covers 96km² and is located approximately 10km east of the historic mining town of Marble Bar in Western Australia's Pilbara region. The project geology comprises:

• Mount Edgar Granitic Complex (eastern and central parts)
• Warrawoona Greenstone Belt (sedimentary and volcanic rocks in western part)

The gold mineralisation identified occurs in Jenkin Granodiorite and Fig Tree Gneiss, associated with quartz veining and pervasive alteration. Interestingly, the orientation of quartz veining at the Sherman and Tiger Prospects appears analogous to those at the Klondyke gold deposit several kilometres south of the project area, though in different host rocks.

Methodical Exploration Approach

Kali Metals has employed a systematic approach to exploration at Marble Bar:

This methodical approach has enabled the company to efficiently target high-potential areas and expand the known mineralised footprint.

Upcoming Exploration Activities

Kali Metals has outlined a comprehensive exploration strategy for the coming months, including:

• Continued reconnaissance and rock chip sampling northwest of Tiger Gold Prospect
• Completion of initial mineralogical study with Microanalysis Australia
• Drone magnetic survey over both Tiger and Sherman Gold Prospects
• Extension of heritage survey northwest of Tiger Gold Prospect
• Drone survey over recently granted tenements E45/6429 and E45/6430
• Initial reconnaissance sampling of newly granted tenements
• Design of a first-pass drilling program based on accumulated data

These activities will further define the extent and characteristics of the gold system, ultimately leading to the company's first drilling program at the project.

Why Investors Should Watch Kali Metals

Kali Metals presents a compelling investment opportunity for several reasons:

1. High-grade gold discovery: The rock chip results (up to 19.2 g/t Au) indicate significant gold potential that remains untested by drilling.

2. Substantial mineralised footprint: A cumulative 1.4km of gold-bearing outcrop provides a large target zone for exploration.

3. Strategic location: The Pilbara region is a proven gold province with excellent infrastructure and mining services.

4. Systematic exploration approach: The company's methodical exploration strategy demonstrates technical rigour and efficient use of resources.

5. Multiple catalysts ahead: With ongoing fieldwork and plans for a maiden drilling program, investors can expect a steady flow of news in the coming months.

6. Diversified portfolio: Beyond Marble Bar, Kali holds 4,029km² of exploration tenure prospective for gold, lithium, and critical minerals across Western Australia, NSW, and Victoria.

As Kali Metals advances its exploration at Marble Bar, the upcoming drilling program will be a significant milestone that could potentially validate and expand upon these impressive early-stage results. With no prior drilling along this newly identified gold trend, the company has the opportunity to make a substantial discovery in an area that has historically been underexplored for gold.
