MB Gold Uncovers New High-Grade Gold Zone at Twin Veins East

MB Gold Strikes Again: New High-Grade Gold Zone Discovered at Twin Veins East

MB Gold Limited (ASX: MBG) has reported a new high-grade gold zone at Twin Veins East within its Marble Bar Gold Project in Western Australia, with assay results confirming mineralisation 500 metres east along strike from the known high-grade shoots at Twin Veins. According to the ASX announcement, the result strengthens the view that gold mineralisation at the prospect is not confined to a single zone and may extend across a broader corridor.

The standout result from the maiden reverse circulation drilling programme was 2m @ 6.73g/t Au from 39m, including 1m @ 13.12g/t Au from 40m in hole 26MBRC031. The company said these results support its geological interpretation and add weight to the broader exploration potential across a 12km gold-in-soil anomaly trend between Douglas Find and Razorback.

"The discovery of a new high-grade zone at Twin Veins East is a great addition to the prospect and highlights the potential of the area," said Logan Barber, CEO and Executive Director of MB Gold.

"In particular, a strong two metres at 6.73 grams per tonne gold from 39 metres, including a high-grade section of one metre at 13.12 grams per tonne gold, validate our geological model and systematic exploration approach as we test the areas along strike from Twin Veins and further afield to Douglas Find and Razorback."

Twin Veins East Extends the Mineralised Footprint

In the announcement, MB Gold said the new assays from Twin Veins East are located along the same 1.5km gold-in-soil anomaly as the central Twin Veins prospect. This matters because it suggests the previously identified high-grade shoots may form part of a larger mineralised system rather than an isolated occurrence.

Mineralisation at Twin Veins East is reported to be hosted in quartz veins within mafic to felsic volcaniclastics affected by strong sericite alteration. In simpler terms, the gold is associated with quartz-filled cracks in volcanic rocks that have been chemically altered by mineral-rich fluids, which is a common setting for structurally controlled gold systems.

The key intercepts reported from Twin Veins East were:

The company's headline summary also referred to 1m @ 6.8g/t Au from 76m in hole 26MBRC034. However, Table 1 in the announcement reported this interval as 6.03g/t Au, so investors are likely to focus on future technical reporting for any reconciliation of rounded or alternate calculation methods.

A further intercept of 1m @ 2.26g/t Au from 59m in hole 26MBRC036 added support to the presence of mineralisation in the eastern zone.

Phase 1 Drilling Results Now Complete Across Twin Veins and Douglas Find

MB Gold has now reported gold assays for all Phase 1 RC drillholes at both the Twin Veins and Douglas Find prospects. This gives the market a fuller view of the company's first systematic drilling campaign at the Marble Bar Gold Project.

The strongest results came from the broader Twin Veins corridor, including the central prospect and Twin Veins East. Best Phase 1 intercepts above the company's reporting threshold of greater than 1.2g/t Au over at least 1m are summarised below.

At Douglas Find, the final assays returned lower-grade results than Twin Veins. MB Gold said mineralisation there is associated with similar alteration, but in a broader and more moderate style. The best assay reported from Douglas Find was 1m @ 2.16g/t Au.

That contrast is useful for investors. It suggests the current highest-priority work remains centred on Twin Veins, where grades and geological definition appear stronger based on the Phase 1 data.

Understanding the Geology: What Is a High-Grade Plunge-Controlled Shoot?

For non-specialist investors, one of the key geological concepts in the update is the idea of a high-grade plunge control or plunge-controlled shoot.

A gold vein system is rarely evenly mineralised from end to end. Instead, higher-grade gold can cluster in certain parts of the structure where the rock geometry allowed mineral-rich fluids to move and deposit metal more efficiently. These concentrated zones are often called shoots.

When geologists say a shoot is plunging, they mean it extends downward through the rock at an angle rather than straight vertically or perfectly flat. That geometry matters because it helps determine where the next drill holes should be placed.

A plunge-controlled shoot is a higher-grade zone within a broader mineralised structure that follows a consistent angle through the rock. If that angle can be identified, drilling can be directed more accurately toward the most prospective parts of the system.

According to the announcement, Twin Veins East shares the same rock type and alteration style as the central Twin Veins prospect. The next technical question is whether this eastern zone also contains a comparable high-grade shoot geometry.

Why Does Shoot Geometry Matter?

If it does, the implications could be important:

• Targeting improves, because follow-up holes can be designed around a defined orientation
• Depth potential becomes more relevant, since plunging shoots can continue below current drill depths
• Scale potential increases, because multiple shoots along the same trend may point to a larger mineralised system

Furthermore, a few key terms from the announcement are worth clarifying for broader context:

• RC drilling: A fast and widely used drilling method that brings rock chips to surface for sampling
• g/t Au: Grams of gold per tonne of rock
• Strike: The horizontal direction a rock structure or mineralised zone follows
• Sericite alteration: Fine white mica formed when hot fluids alter the host rock, often linked to gold systems
• Gold-in-soil anomaly: Elevated gold detected in surface soils, used to identify areas that may host mineralisation below
• Induced Polarisation (IP) survey: A geophysical method that measures how rocks respond to electrical current, helping identify hidden mineralised zones

Phase 2 Drilling and Surveys Set Up the Next Catalysts

The ASX update said preparations for Phase 2 drilling are now underway. The planned programme is expected to combine extensional drilling at known prospects with the first drill testing of a new target.

The Phase 2 work outlined in the announcement includes:

The inclusion of Razorback, around 5km east of Twin Veins, is likely to draw investor attention. According to the company, Razorback sits within the same broader 12km gold-in-soil anomaly corridor that links Douglas Find in the west to Razorback in the east.

In addition, the company said the IP survey is nearing completion, while a LiDAR survey has already been completed and a HYMAP survey is planned. Together, these datasets are expected to help refine drill targeting across the project area, including at Murphy Well, which has not yet been drill tested.

Why the Marble Bar Gold Project Is Attracting Attention

The Marble Bar Gold Project remains at an exploration stage, but the latest update provides several points that may support investor interest.

First, the company has reported high-grade gold assays from more than one zone within the Twin Veins area. Second, mineralisation has now been traced into a new eastern zone 500m along strike, which may indicate broader continuity. Third, much of the 12km anomalous trend remains lightly tested by drilling.

Project logistics are also relevant. MB Gold said the project is located 150km from Port Hedland via sealed road and 40km from the Marble Bar townsite, which may reduce some access and mobilisation constraints compared with more remote regional projects.

Key project metrics from the announcement are summarised below.

What MB Gold's Latest Drilling Update Means for Investors

The latest drilling update suggests MB Gold is building a stronger geological case around Twin Veins as the leading target within the Marble Bar Gold Project. The new Twin Veins East results are important because they indicate high-grade gold may occur in more than one position along the trend.

At the same time, the results from Douglas Find were more modest, which helps sharpen the market's focus on where the most promising mineralisation currently sits. That kind of contrast can be useful in early-stage exploration, where prioritisation of capital and drilling effort matters considerably.

Three Key Reasons to Watch Phase 2

The next phase of drilling is likely to be watched for three main reasons:

1. Twin Veins extensions could show whether the known high-grade zones continue down plunge
2. Twin Veins East follow-up work may determine whether a second high-grade shoot is present
3. Razorback drilling will test fresh ground within the same broader anomalous corridor

For investors following ASX gold exploration stories, the combination of new high-grade assays, an expanding mineralised footprint and several pending exploration catalysts means MB Gold is likely to remain on the watchlist as Phase 2 approaches.
