Battery Age Minerals Defines 21 Priority Targets at Apex Germanium-Gallium Project

Battery Age Minerals Defines 21 Priority Targets at Apex Germanium-Gallium Project in Utah

Battery Age Minerals (ASX: BM8) has reported the results of a high-resolution remote sensing study at its Apex Germanium-Gallium Project in Utah, identifying 21 exploration targets across its Apex North, East and South tenements. The work outlined 14 first-priority and 7 second-priority targets in settings considered analogous to the historic Apex Mine, a past-producing germanium-gallium-copper occurrence in Washington County, Utah.

The announcement matters because it shifts the Apex project from broad regional concept work into a more defined targeting phase. Battery Age has set out a sequenced follow-up plan including incoming short-wave infrared data, field mapping, surface sampling and potential geophysical surveys and drill testing, subject to field results.

Remote Sensing Program Identifies 21 Ranked Targets

The study was interpreted by Geo Spectra Pty Ltd and covered approximately 65 km² of detailed project area analysis within a broader ~1,500 km² regional study. Battery Age said the work combined newly acquired WorldView-3 satellite imagery with publicly available ASTER and Sentinel-2A datasets, plus a LiDAR-derived Digital Elevation Model (DEM).

This multi-layered approach was used to identify where favourable alteration signatures, structural corridors and prospective carbonate host rocks overlap. In the announcement, the company confirmed this produced multiple target areas across all three tenements.

The current target inventory is summarised below.

Several of these targets occur at interpreted fault intersections and within favourable carbonate units, including the Pakoon Dolomite and, to a lesser extent, the Redwall Limestone. Battery Age said these settings are considered analogous to the environment of the historic Apex Mine.

What the CEO Had to Say

"These results mark an important step forward for the Apex Project. By integrating high-resolution satellite data with our structural and geological interpretation, we've defined 14 high-priority targets across all three tenements, several in settings we consider analogous to the historic Apex Mine," said Sebastian Kneer, Chief Executive Officer of Battery Age Minerals.

Why Is the Apex District Drawing Attention?

The Apex project is located approximately 20 km southwest of St George, Utah, adjacent to the historic Apex Mine. According to Battery Age, the mine is a carbonate-hosted polymetallic system with copper, lead, zinc, germanium and gallium associated with iron-rich dolomite and sulphide mineral assemblages.

That geology is important because the district is unusual in a US context. Battery Age referenced US Geological Survey work describing the historic Apex Mine as one of the highest-grade germanium-gallium systems documented in the United States.

Recent corporate activity has also increased market attention on the area. The ASX announcement noted that Blue Moon Metals, listed on NASDAQ, recently acquired the historic Apex Mine. For investors, that transaction does not confirm mineralisation on Battery Age's surrounding tenure, but it does indicate renewed commercial interest in the district.

Why Germanium and Gallium Matter

Germanium and gallium remain widely watched critical mineral markets because of their use in:

• Semiconductors
• Fibre optics
• Solar technologies
• Night-vision systems
• 5G and communications infrastructure

Battery Age stated that its broader strategy includes critical mineral exploration as well as germanium enrichment technologies and downstream application development. In the context of this announcement, however, the immediate focus remains on exploration targeting at the Apex Germanium-Gallium Project.

How Were the Targets Generated?

In the report, Battery Age explained that the survey was designed to map both alteration mineralogy and structural controls associated with the Apex style of mineralisation.

Key Data Inputs

The main data inputs included:

• WorldView-3 panchromatic data at 0.31 m resolution
• WorldView-3 VNIR multispectral data at 1.24 m resolution across 8 bands
• ASTER and Sentinel-2A multispectral imagery
• A 30 m regional DEM
• A higher-resolution LiDAR-derived DEM
• Published geological mapping of the St George, Utah area

Processing was completed using ENVI 6.1, QGIS and ArcGIS Pro. Furthermore, the workflow included radiometric and geometric corrections, vegetation masking, mineral mapping, structural interpretation and final target generation.

Key Mineral Signatures and Target Criteria

The mineral mapping focused on several key signatures:

• Ferric iron oxides, including hematite and goethite
• Silica intensity
• Clay minerals
• Carbonate minerals, including calcite and dolomite

Battery Age said target generation placed particular emphasis on:

• Discrete iron oxide anomalies
• Strong goethite signatures
• Clay-carbonate-silica alteration responses
• Northwest- and northeast-trending fault corridors
• Fault intersections with north-south structures

For investors, this matters because the company is not selecting targets randomly across a large tenure package. Instead, the report outlines a methodical ranking process based on mapped geological features that are considered favourable for the deposit style being pursued.

What Does Carbonate-Hosted Polymetallic Mineralisation Mean?

This deposit style is central to the Apex story, so it is worth clarifying in plain language. Carbonate-hosted polymetallic mineralisation refers to metal-bearing fluids moving through fractures and faults in carbonate rocks such as dolomite and limestone.

At the Apex Germanium-Gallium Project, the prospective host rocks are mainly the Permian Pakoon Dolomite and the Lower Mississippian Redwall Limestone. These rocks can be chemically reactive, which may help mineral-bearing fluids deposit metals where conditions are suitable.

The term polymetallic simply means more than one metal occurs in the same mineral system. In this district, that includes copper, lead, zinc, germanium and gallium.

Useful Technical Terms Explained

A few technical terms from the report are also worth understanding:

• Goethite: an iron oxide mineral that can form during weathering and may help highlight altered zones
• LiDAR DEM: a detailed topographic model produced using laser-based elevation data, useful for spotting subtle fault-related landforms
• Structural corridor: a zone of related faults that may have acted as pathways for mineral-bearing fluids
• SWIR data: short-wave infrared data, which helps map clays, carbonates and sulphates linked to alteration

Structurally controlled systems can often be narrowed down by combining geology, topography and alteration mapping before any drilling takes place. That is effectively the stage Battery Age has now reached.

Structural Interpretation Is Central to the Exploration Model

According to the announcement, the Apex district sits within the Basin and Range Province, which has a history of compression followed by extension. Battery Age said this structural history created two principal fault sets across the project area.

The company identified:

• North-south faults with mainly vertical movement
• Northwest-southeast and northeast-southwest faults with lateral movement

Battery Age considers the oblique fault sets, especially where they intersect with north-south faults, to be favourable sites for mineralisation. In carbonate-hosted systems, fault intersections can create open pathways for fluid flow and localised traps for metal deposition. That makes structural interpretation a practical first filter before field sampling or drilling.

Next Steps: SWIR Data, Field Mapping and Surface Sampling

The company has already outlined the next stages of work, with additional WorldView-3 SWIR data expected to refine the alteration interpretation and improve target ranking ahead of field work. The staged work programme described in the report is summarised below.

Battery Age said the remote sensing results will directly guide the upcoming field exploration programme. Planned work is expected to include mapping and sampling over both first- and second-priority targets.

Importantly, the company also stated that no mineralisation has been discovered or confirmed on its tenements through this remote sensing programme. The targets are interpretive exploration areas only and require field validation.

"Incoming WorldView-3 SWIR data will sharpen our target ranking, followed by ground-truthing, mapping and sampling, building toward testing of the most prospective areas," Kneer said in the announcement.

CFO Transition Announced Alongside Exploration Update

Battery Age also used the release to announce a finance leadership transition. Current Chief Financial Officer Paul Hughes will step down from the role effective 15 August 2026, while Jay Stephenson will commence as CFO on 1 August 2026 to allow for an orderly handover.

According to the company, Stephenson brings more than 35 years of experience in business development and corporate advisory roles, including approximately 29 years as a Director, CFO and Company Secretary across listed and unlisted entities in the resources sector and other industries in Australia and overseas.

For investors, this is a secondary point relative to the exploration update. However, it does signal continuity in the company's corporate function as the Apex project moves into a more active field stage.

Why Investors May Keep Watching BM8

The June 2026 ASX announcement does not report assays, drilling or a mineral discovery. What it does report is a more advanced technical framework for exploration at a project adjacent to a historically significant germanium-gallium mine.

Several features stand out from an investor perspective:

• Project location: the tenure is adjacent to and surrounding the historic Apex Mine
• Defined pipeline: the company has moved from concept to 21 ranked targets
• Technical method: targeting is based on integrated satellite, elevation, structural and geological data
• Near-term catalysts: incoming SWIR interpretation, field mapping and geochemical sampling may generate regular project updates
• Commodity exposure: germanium and gallium remain relevant to electronics and communications supply chains

The key question now is whether ground-based work supports the remote sensing interpretation. That is the next step that will determine whether any of the 21 targets progress to geophysics or drill testing.

Battery Age's latest report places the Apex Germanium-Gallium Project at a clearer decision point. The target generation phase is largely in place, the ranking process is expected to improve with incoming SWIR data, and field validation remains the next material test of the company's exploration model.
