Excalibur Metals Corp Provides Exploration Update on Developing Rangefront Target at its Bellehelen Silver-Gold Project, Nye County, Nevada
Excalibur Metals Corp. has provided an exploration update on the developing Rangefront Target at the Company’s Bellehelen Silver-Gold Project, Nye County, Nevada. Soil sampling has identified a large, coherent multi-element anomaly (Sb-As-Hg) vectoring towards the Rangefront structural corridor, where epithermal alteration is obscured by gravel cover. CSAMT geophysics reveal an interpreted structure that corresponds with mapped faults along the Rangefront structural corridor, better defining the zone at depth. Rangefront is slated as a priority target for the Company’s next drill campaign, along with follow-up drilling at Spyglass Ridge, anticipated in late 2026 or early 2027. The Company will remain focused on identifying, advancing, and prioritizing targets at Bellehelen to optimize the chances of discovery during subsequent drilling. The Rangefront Target is located along the Bellehelen structural corridor approximately eight kilometres northwest of the Spyglass Ridge Target. Rangefront was first identified through airborne AVIRIS hyperspectral data, which highlighted a multi-kilometer zone of increasing kaolinite alteration intensity interpreted as the upper “cap” of a precious metals epithermal system. Follow-up reconnaissance rock chip sampling returned anomalous mercury, antimony, and arsenic across the alteration footprint, consistent with the high-level, gold-depleted portion of a preserved epithermal system. The Company completed a systematic soil sampling grid across the Rangefront alteration anomaly as well as a CSAMT survey. Results from both programs have now been received, with the soil samples defining a strong, coherent anomaly in antimony, arsenic, mercury, and gold concentrated immediately along the rangefront — the contact where pre-mineral bedrock outcrop is overlain to the west by post-mineral alluvial cover. The CSAMT results reveal a marked discontinuity in resistivity values across a west-dipping plane near the location of the rangefront; Excalibur interprets this discontinuity to correspond to a west-dipping fault that constitutes a structural target for epithermal mineralization. Soil geochemistry suggests increasing antimony, arsenic, and gold values toward the west-southwest beneath post-mineral cover. This trend suggests the system strengthens toward the interpreted rangefront structure and supports the Company's belief that the most prospective portion of the target remains concealed beneath shallow cover. Sb, As, and Au vector towards the west-southwest underneath post-mineral cover. Hg samples are elevated throughout the grid, which is typical of the upper portions of an epithermal system. KLM Geoscience completed a CSAMT geophysical survey across Rangefront to better understand the structural architecture beneath shallow post-mineral cover. The survey identified a prominent west-dipping structural feature that separates areas of contrasting resistivity. Excalibur interprets this feature as a fault zone that may represent an important control on hydrothermal fluid flow and mineralization. The interpreted structure closely corresponds with a mapped rangefront fault, increasing confidence in the Company's geological model. This structural corridor coincides with the direction of increasing alteration and pathfinder geochemistry identified in surface sampling. These datasets suggest that the rangefront structure may be a key control on the hydrothermal system and represents a priority target for future drilling. Over the remainder of 2026, Excalibur will continue advancing exploration across the Bellehelen Project through additional geological mapping, surface sampling, geophysical surveys, and integrated interpretation of recent drilling results. This work is expected to support the refinement and prioritization of drill targets at Rangefront, Spyglass Ridge, and other prospective areas ahead of the Company's next phase of drilling.
