Butte Silver Explorer Hits 994.2 g/t AgEq 125m Beyond Resource

Source: Streetwise Reports 09/08/2026

SilverBow Mining Corp (SBMT) reports high-grade silver intercepts at Rainbow Block in Butte, Montana, expanding potential beyond current resource. Next steps include updated MRE in 2027.

SilverBow Mining Corp. (SBMT:NYSEAmerican) reported assay results from drill holes SBM26-03 and SBM26-04 at its Rainbow Block Project in Butte, Montana, including a high-grade Badger Vein intersection located approximately 125 meters beyond the boundary of the current Inferred Mineral Resource estimate.

Strongest Intercept to Date Expands High-Grade Potential

Drill hole SBM26-03 returned the strongest interval drilled so far at the Rainbow Block. The 4.0-meter intercept graded 994.2 grams per tonne silver equivalent, including a 2.3-meter section at 1,586.1 g/t AgEq.

These results sit roughly 125 meters west of an earlier high-grade hit and lie completely outside the current resource boundary.

Key Investor Takeaways

• Hole SBM26-03 delivered 4.0 m at 994.2 g/t AgEq, the best intercept reported to date at the Rainbow Block.
• The high-grade zone lies 125 m beyond the current Inferred Mineral Resource, confirming the westerly extension of the Badger Vein.
• Three surface rigs are active; 13,500 feet of a 25,000-foot Phase I program are complete, with all intercepts outside existing resource limits.
• An updated mineral resource estimate is scheduled for the first half of 2027.
• Underground access has been re-established, and underground drilling is planned to begin in Q4 2026.
• Analysts have issued Speculative Buy ratings, with price targets substantially above the recent share price.

Why These Results Matter for Retail Investors

High-grade intercepts outside a known resource can increase the size and grade of future resource estimates. The new data also support the company’s view that the Badger Vein continues westward and merges with the State Vein system.

This geological continuity is important because it suggests additional tonnage may be added when the resource is updated in 2027.

Company Position and Asset Overview

The Rainbow Block hosts an Inferred Mineral Resource of 10.4 million tonnes grading 507.4 g/t AgEq. That estimate contains 49.16 million ounces of silver, 0.55 million ounces of gold, 0.47 million tonnes of zinc, and 0.13 million tonnes of lead.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. The current drilling program is designed to test extensions beyond these boundaries, and none of the new intercepts fall inside the existing estimate.

Next Catalysts: Drilling, Underground Work, and Resource Update

Surface drilling with three rigs continues through 2026. The company has completed rehabilitation of the Chief Joseph Portal, restoring underground access. Underground drilling is scheduled to start in the fourth quarter of 2026.

Over the next 24 months, the company plans additional declines, drill bays, and evaluation of nearby blocks secured with no royalty. An updated resource estimate incorporating the new drilling and historical data is expected in the first half of 2027.

Silver Market Context and Timing

FX Empire reported on September 7 that silver had remained within a US$64 to US$68 trading range as higher interest-rate expectations pressured the metal. Industrial demand for silver in electronics, solar panels, and medical technologies continues to grow while mine supply has not kept pace.

The Motley Fool also examined the silver market on September 7, noting investor uncertainty around interest rates and broader economic conditions.

Trading Economics’ September 8 market summary showed silver at US$65.996 per ounce, up more than 61 percent over the prior year.

Views and Valuation Context

Research Capital analyst Stuart McDougall gave the company a Speculative Buy rating and a US$25.60 per share target price.

Cantor Fitzgerald analyst Matthew O’Keefe also gave the company a Speculative Buy rating and a US$19.80 per share target, representing a potential 125 percent return from the US$8.81 share price cited in the report. O’Keefe described the latest results as positive evidence of high-grade mineralization beyond the current resource and expects the 2027 update to expand the high-grade resource.

In a September 2 commentary, Peter Krauth of The Silver Stock Investor described Silver Bow Mining’s latest Rainbow Block drill results as impressive new drill results and maintained a full weighting, viewing the shares as attractive on weakness.

Hole SBM26-03 intersected 4.0 meters grading 994.2 g/t AgEq at the Badger Vein, including 2.3 meters at 1,586.1 g/t AgEq. This is the highest-grade interval reported to date at the project.

Where do the new intercepts sit relative to the resource?

The high-grade Badger Vein intercept lies approximately 125 meters beyond the current Inferred Mineral Resource boundary. All new mineralized intercepts from the ongoing program are outside existing resource limits.

When is the next resource update expected?

Silver Bow Mining plans to deliver an updated mineral resource estimate for the Rainbow Block in the first half of 2027, incorporating both new drilling and validated historical data.

What is the status of underground work?

Rehabilitation of the Chief Joseph Portal is complete. Underground drilling is scheduled to begin in the fourth quarter of 2026, with additional declines and drill bays planned over the next 24 months.

The latest drill results confirm high-grade mineralization outside the current resource at the Rainbow Block. Investors should monitor assay results from the remaining surface program, progress on underground access, and the 2027 resource update for further clarity on project scale.
