MB Gold Drills Into Momentum: Fresh Assay Results Strengthen the Twin Veins Story
MB Gold Limited (ASX: MBG) has released a second batch of positive assay results from its maiden reverse circulation (RC) drilling campaign at the Marble Bar Gold Project in Western Australia's Pilbara region. The MB Gold Marble Bar Gold Project drilling results at Twin Veins are becoming increasingly compelling for investors tracking early-stage gold exploration opportunities.
The latest results include 8m @ 2.5g/t Au from 48m in hole 26MBRC015 and 5m @ 1.25g/t Au from 82m in hole 26MBRC019, adding to the standout intercept of 20m @ 1.74g/t Au from 81m (including 7m @ 4.06g/t Au) announced on 20 May 2026.
With the Phase 1 program now complete at 6,369m drilled and 31 holes still awaiting assay, the company is building a meaningful geological dataset that is beginning to reveal high-grade shoot geometries extending at depth.
"Our understanding of the plunge of higher-grade zones has increased. We are starting to identify the potential for multiple shoots extending to depth, which will be targeted as part of the Phase 2 drill program."
— Logan Barber, CEO and Executive Director, MB Gold Limited

What the Latest Assay Results Actually Tell Us
Gold assay results have now been reported across the first 20 drillholes at Twin Veins. The current batch covers holes 26MBRC007 through 26MBRC020, providing a more detailed view of how mineralisation is distributed across the system.
The table below summarises the significant intercepts from this announcement, calculated using a 0.3g/t Au cut-off grade, minimum 1m thickness, and up to 2m internal dilution:
| Hole ID | From (m) | To (m) | Thickness (m) | Grade (Au g/t) |
|---|---|---|---|---|
| 26MBRC007 | 105 | 106 | 1 | 0.62 |
| 26MBRC007 | 122 | 123 | 1 | 1.32 |
| 26MBRC008 | 30 | 31 | 1 | 1.34 |
| 26MBRC010 | 71 | 72 | 1 | 0.60 |
| 26MBRC011 | 88 | 90 | 2 | 0.42 |
| 26MBRC013 | 21 | 22 | 1 | 0.77 |
| 26MBRC015 | 48 | 56 | 8 | 2.50 |
| 26MBRC016 | 23 | 29 | 6 | 0.49 |
| 26MBRC016 | 33 | 35 | 2 | 0.78 |
| 26MBRC017 | 8 | 9 | 1 | 1.31 |
| 26MBRC017 | 42 | 43 | 1 | 0.36 |
| 26MBRC017 | 63 | 69 | 6 | 0.60 |
| 26MBRC018 | 36 | 37 | 1 | 0.88 |
| 26MBRC018 | 91 | 98 | 7 | 0.51 |
| 26MBRC019 | 82 | 87 | 5 | 1.25 |
The headline intercepts demonstrate that meaningful gold grades are being encountered at multiple depths and across different parts of the system. Importantly, the mineralisation remains open at depth, meaning the system has not been closed off by drilling — a technically positive signal for investors following the project's early-stage development.
Understanding "Shoot Geometry" — Why Does It Matter for Investors?
One of the more significant statements in this announcement is the reference to high-grade shoot geometries beginning to emerge from the drilling data. For investors unfamiliar with this concept, here is a plain-language explanation of why it matters.
What Is a High-Grade Shoot?
In gold deposits hosted within quartz vein systems, gold is rarely distributed evenly. Instead, it tends to concentrate in discrete, elongated zones called "shoots." These shoots form where favourable structural conditions — such as changes in vein orientation, junctions between veins, or zones of dilation — have allowed gold-bearing fluids to deposit metal preferentially.
Why Does Shoot Geometry Matter?
- Shoots are typically higher-grade than the surrounding vein system, meaning they can significantly improve the economic attractiveness of a deposit.
- Once a shoot is identified, geologists can predict its plunge direction, essentially forecasting where the gold is heading at depth and allowing drill programs to be targeted efficiently.
- Multiple shoots within a single system multiply the potential resource. MB Gold's team is now suggesting that multiple high-grade shoots may be present at Twin Veins.
Furthermore, understanding shoot geometry early in a project's life allows for considerably more capital-efficient exploration in subsequent phases.
Key Terms for Understanding Results
| Term | Definition |
|---|---|
| RC Drilling | Reverse Circulation drilling, where rock chips are returned to surface through the drill rods, providing continuous rock samples |
| Assay | Laboratory analysis of a sample to determine gold or metal content, typically expressed in grams per tonne (g/t) |
| Cut-off grade | The minimum grade used to define a significant mineralised intercept |
| g/t Au | Grams of gold per tonne of rock, the standard unit for reporting gold grades |
| Strike length | The horizontal distance along which mineralisation has been identified |
| Open at depth | Describes a mineralised zone that has not been closed off by drilling |
| High-grade shoot | A localised concentration of higher-grade gold within a broader mineralised system |
| LIDAR | Light Detection and Ranging, a remote sensing technology using laser pulses to produce high-resolution topographic maps |
| Hyperspectral survey | An airborne survey that detects mineral types at the surface based on how they reflect different wavelengths of light |
Phase 1 Complete — A Fully Loaded Pipeline Ahead
The Phase 1 drill program has been completed safely and efficiently, with 6,369m drilled across the Twin Veins and Douglas Find prospects. The program generated a substantial dataset, much of which is still being processed.
Where things stand right now:
- Results received and reported: First 20 drillholes at Twin Veins (26MBRC001 to 26MBRC020)
- Assays still pending: 31 drillholes across Twin Veins and Douglas Find
- Results from pending holes: Expected within the coming month
This represents a meaningful pipeline of upcoming news flow. The Douglas Find results, in particular, are yet to be seen by the market, representing a fresh catalyst that could further expand the project's footprint.
Technology Programs Now Underway
In addition to drilling, MB Gold is deploying modern remote sensing tools to accelerate exploration targeting.
-
LIDAR survey completed — A drone-based Light Detection and Ranging survey has been flown over the Twin Veins, Douglas Find, Razorback, and Murphy Well prospects. This delivers high-resolution topographic data and orthophotos to support field mapping, drill pad planning, and future resource modelling.
-
Hyperspectral survey planned — A project-wide airborne hyperspectral survey will be flown in coming months. The survey will generate mineral abundance maps to identify alteration zones associated with gold mineralisation, and will be applied regionally to identify new target areas beyond those already being drilled.
What Comes Next: The Phase 2 Roadmap
MB Gold has outlined a clear path forward, and the near-term schedule is packed with potential catalysts.
| Upcoming Milestone | Detail | Timing |
|---|---|---|
| Remaining Phase 1 assay results | 31 drillholes at Twin Veins and Douglas Find | Expected within coming month |
| Initial Douglas Find assay results | First look at the second prospect | Part of pending batch |
| Airborne hyperspectral survey | Project-wide mineral mapping | Coming months |
| Phase 2 drill program | 6,000m targeting high-grade shoot extensions | Planning underway |
| Razorback prospect drilling | New prospect approximately 5km east of Twin Veins | Future program |
The Phase 2 program has been specifically designed around the shoot geometries being identified through Phase 1 results. Rather than broad exploration, this represents increasingly targeted drilling — which tends to be more capital-efficient and more likely to deliver high-grade intercepts.
The Investment Case: A Junior Explorer with Building Momentum
MB Gold is an early-stage gold explorer, and the Marble Bar Gold Project sits at the heart of its investment thesis. Several elements of the current program reinforce why the company warrants investor attention.
Project Scale and Prospectivity
- The project spans a 12km strike length of gold-in-soil geochemical anomalies across multiple prospects
- It sits within the Archean Pilbara Craton, one of Australia's most historically productive and geologically well-understood gold terrains
- Historic results include 7m @ 4.78g/t from 11m by Global Lithium in 2021, and rock chip grades of up to 54.60g/t Au, providing geological validation for the project's high-grade potential
Infrastructure and Tenure Advantages
The project's logistics profile is notably favourable compared to many remote Australian exploration assets.
- Located just 150km from Port Hedland via sealed road, significantly reducing logistical costs
- 40km from the Marble Bar townsite and 60km from AIM Mining Corporation's Warrawoona Operations, an operating gold mine in the same district
- MB Gold holds precious metals rights over tenement E45/4631 with no royalty covering any future resource — a clean tenure structure that preserves value for shareholders
Quality of Exploration Execution
Rigorous QA/QC protocols are in place, including certified reference material standards inserted at 1 in every 20 samples, field duplicates at 1 in every 25 samples, and laboratory blanks and standards throughout. Sample recovery through mineralised zones is estimated at greater than 90%.

Why Investors Should Keep Watching MB Gold
The Twin Veins story is still being written. With only 20 of the program's drillholes reported to date and 31 more awaiting assay, the majority of Phase 1's data has not yet reached the market. The emerging shoot geometry adds structural confidence to what began as a target defined primarily by surface geochemistry and widely spaced historical drilling.
For investors, the key points to track are:
- The grade and thickness of remaining Phase 1 assay results, particularly from Douglas Find
- The definition of high-grade shoot targets as the geological model matures, and how Phase 2 drilling is designed to test them
- The hyperspectral survey results, which could identify new regional targets and expand the exploration pipeline
- The scale and results of the 6,000m Phase 2 drill program, representing the next major value inflection point
MB Gold has positioned itself as an active and disciplined gold explorer in one of Australia's most prospective geological settings, with significant near-term news flow expected from 31 pending assay results, a maiden look at Douglas Find, and a 6,000m Phase 2 drill program designed to test high-grade shoot extensions at depth. Investors following the junior gold exploration space should have the MB Gold Marble Bar Gold Project drilling results at Twin Veins firmly on their radar.
