Rapid Critical Metals Delivers High-Grade Results and 300m Southern Extension at Webbs Silver

Webbs Silver Breaks Wide Open: Exceptional Grades, 300m Southern Extension, and a Third Rig on the Way

Rapid Critical Metals Limited (ASX: RCM, RCMO) has reported a strong new batch of drill assays from its 100%-owned Webbs Silver Project in northern New South Wales, with results from 20 holes indicating both high-grade silver and a larger mineralised footprint. The strongest result, from WSRC0019, returned 4m at 1,230 g/t silver equivalent (AgEQ) from 136m, within a broader 37.4m interval at 278.8 g/t AgEQ from 126.6m.

According to the ASX announcement, the latest drilling has also extended mineralisation by more than 300m to the south of the current resource in hole WSRC0012, while hole WSRC0028 returned another high-grade intercept about 1 kilometre to the north. For investors, that combination matters because it points to both resource growth potential and improving geological confidence across the Webbs system.

"WSRC0019 is a standout result by any measure, 4m at 1,230 g/t silver equivalent, sitting inside a 37.4m zone averaging 278.8 g/t. Exceptional grade and real width in the same intersection is exactly what we have been drilling for," said Byron Miles, Managing Director.

"Just as important, WSRC0012 has pushed the system more than 300m further south and WSRC0028 has delivered a second exceptional intercept a kilometre to the north. Webbs is behaving like a mineralised corridor rather than a single lode, and it is still open in every direction we test."

The Headline Drill Results from Webbs

The key assay results outlined in the announcement show a recurring pattern: narrower zones of very high-grade silver within broader mineralised intervals. That can be important because it suggests the project may host more than one mineralised structure rather than a single isolated vein.

In the report, Rapid also highlighted the 981 g/t silver result in WSRC0019 as being approximately 25% higher than the 23 oz/t average grade mined historically at Webbs between 1884 and 1901. Historical comparisons need to be treated carefully, but they do provide useful context for how current drill grades compare with past production from the same district.

Why Silver Equivalent Matters in a Polymetallic System

Webbs is not a silver-only system. The mineralisation reported by Rapid also contains copper, lead and zinc, which means that looking at silver grade alone may understate the value of an intercept. That is why the company reports silver equivalent, or AgEQ.

What Is AgEQ?

Silver equivalent is a method used to combine the value contribution of several metals into one number expressed as silver grade. In simple terms, it asks: if the copper, lead and zinc in a drill interval were converted into their silver value, what total silver grade would that represent?

According to the announcement, Rapid uses the following formula:

AgEQ = Ag g/t + 89.29 × Cu(%) + 19.67 × Pb(%) + 29.33 × Zn(%)

The company stated that this calculation is based on:

• Five-year average metal prices sourced from the International Monetary Fund to the end of May 2026
• Metallurgical recoveries from 2021 testwork:
  • Silver: 97.3%
  • Copper: 85.0%
  • Lead: 94.7%
  • Zinc: 98.7%

Why Investors Use AgEQ

For investors comparing drill holes, AgEQ provides a more complete measure of metal content than silver alone. A result such as 37.4m at 278.8 g/t AgEQ reflects the combined contribution of silver, copper, lead and zinc across the interval.

That does not mean AgEQ is a substitute for detailed project economics. Metal equivalent figures depend on assumptions around prices and recoveries. Even so, they are a widely used screening tool when assessing polymetallic exploration results.

Furthermore, for non-specialist readers, the following glossary may help clarify key terms used throughout this article:

• AgEQ: A combined grade measure that converts silver, copper, lead and zinc into a silver-equivalent grade
• g/t: Grams per tonne, the standard unit for precious metal grade
• oz/t: Troy ounces per tonne, another common silver reporting unit
• Strike: The length of a mineralised feature across the ground
• Open at depth or along strike: Drilling has not yet closed off the mineralisation, so it may continue further

Evidence Is Building for a Larger Mineralised Corridor

One of the more important takeaways from the update is not just the grade itself, but the growing footprint of mineralisation across the project area. In the announcement, management stated that Webbs appears to be behaving more like a broader mineralised corridor hosting stacked or parallel lodes than a single lode.

That interpretation is based on several observations from the current drilling programme:

• WSRC0012 extended mineralisation more than 300m south of the current resource
• WSRC0028 returned a strong result roughly 1 kilometre north of that southern extension
• WSRC0019, WSRC0017, WSRC0021 and WSRC0029 all reported mineralised intervals across different positions and depths within the system
• Mineralisation is reported to remain open in every direction tested

In plain terms, a lode is a tabular mineralised body, often following faults or fractures in rock. A stacked or parallel lode system means there may be several nearby mineralised zones rather than one narrow target. For investors, that can be relevant because multiple lodes may support a larger resource base if continuity is confirmed through more drilling.

The geological setting described in the ASX release is a structurally hosted fracture vein system within the New England Fold Belt. The company said the lode generally dips steeply to the west, at approximately 80 to 85 degrees, and that individual sulphide-rich veins sit at slightly different angles within the broader lode zone. The report describes this arrangement as a "kink band" structure.

While that is technical language, the practical implication is straightforward: the mineralised system may have enough structural complexity to host repeated zones of silver-rich mineralisation across a wider corridor.

Resource Confidence May Improve as Drilling Continues

The ASX update did more than point to extensions. It also stated that the latest assays have greatly improved the confidence in parts of the ore body, with some areas likely to move into higher levels of resource classification.

For non-specialist investors, resource classification under the JORC Code reflects the level of geological confidence attached to a mineral resource estimate. Higher-confidence categories generally rely on closer drill spacing and better understanding of continuity.

While the company has not yet published an updated resource estimate in this release, the suggestion is that infill drilling may strengthen parts of the existing model. That matters because markets often distinguish between simple exploration upside and a project that is progressively being de-risked through more data. Better classification does not guarantee development outcomes, but it can improve the credibility of a deposit in the eyes of investors and analysts.

Drilling Activity Is Accelerating Across Webbs and Webbs Consol

Rapid is also increasing the pace of exploration. According to the announcement, the company has:

• Booked a third drill rig to join the current programme within weeks
• Received environmental approvals for the Webbs Consol Project
• Begun integrating the latest assays into updated geological and resource models
• Continued to wait on the balance of assays from holes already drilled in the current programme

The next phase outlined in the report includes:

1. Follow-up drilling on interpreted parallel lodes and the new southern extension at Webbs
2. Resource growth and discovery drilling along the Webbs-Webbs Consol corridor
3. Updated geological and resource modelling
4. Pending assay releases from the remainder of the current programme

For investors, the practical takeaway is straightforward. More rigs can increase the rate of news flow, whilst newly approved ground at Webbs Consol expands the area available for systematic testing.

Why the Webbs Update Matters to Investors

This announcement stands out because it reports more than a single high-grade result. It combines grade, width, step-out success, and programme acceleration in one update. Several investor-relevant points emerge from the release.

1. High Grades Have Been Repeated Across Multiple Holes

WSRC0019 and WSRC0028 both returned high AgEQ values, and WSRC0017 added another strong result over meaningful width. Repetition across multiple holes is generally more informative than a single isolated intercept.

2. The Project Footprint Appears to Be Growing

The 300m southern extension in WSRC0012 indicates that current mineralisation extends beyond the existing resource boundary. If follow-up drilling confirms continuity, that could support future resource growth.

3. Width and Grade Are Appearing Together

The broader 37.4m interval at 278.8 g/t AgEQ in WSRC0019 is relevant because width can influence mining scenarios, subject to future technical studies. Narrow, very high-grade veins can be attractive, but broader mineralised zones may offer additional optionality if continuity and geometry hold up.

4. Geological Confidence May Be Improving

The company stated that this drilling is likely to move parts of the ore body into higher resource confidence categories. That signals progress beyond early-stage target testing.

5. Near-Term Catalysts Remain in Place

With a third rig due to arrive, further assays pending, and approvals in hand for Webbs Consol, Rapid appears set for an active second half of 2026 according to the company's stated plans.

Rapid Critical Metals Portfolio Snapshot

While Webbs is the immediate focus of this announcement, Rapid also holds a broader exploration portfolio. In addition to its silver assets, the company maintains exposure to technology metals through its Canadian project.

The concentration of silver assets in northern New South Wales may allow the company to apply regional geological knowledge across multiple projects. However, each asset still requires project-specific drilling and technical work to advance.

What to Watch Next at Webbs

The immediate focus is likely to remain on three areas:

• Pending assays from the rest of the current drilling programme
• Follow-up drilling around the new southern extension and interpreted parallel lodes
• Any future resource model updates reflecting the latest drill data

According to the ASX release, Rapid considers Webbs to be open along strike and at depth. That remains a geological interpretation until additional drilling is completed, but the current results have added meaningful support to that view.

Overall, the Webbs announcement presents a clear exploration narrative. Rapid has reported a high-grade headline intercept, broader mineralised intervals, a material southern extension, another strong northern hit, and an increasing drilling pace. For ASX investors following silver exploration stories, the next round of assays and any subsequent resource update are likely to be the key markers to monitor.
