Excalibur Metals Corp. (TSXV: EXCL,OTC:EXCBF) (OTCQB: EXCBF) ("Excalibur" or the "Company") is pleased to report results from its ground gravity survey at the Rangefront Target ("Rangefront") at the Company's Bellehelen Silver-Gold Project ("Bellehelen" or the "Project"), Nye County, Nevada.
The survey was designed to improve the Company's understanding of the geology and structural setting at the intersection of the Bellehelen and Rangefront faults and adjacent post-mineral cover. The survey results corroborate the existing interpretation that the observed mineral alteration and geochemical anomalies likely overlie the structural intersection of these two major faults . The gravity results are being integrated with geological observations, geochemical sampling results and previously reported controlled-source audio-frequency magnetotelluric ("CSAMT") data (as outlined in the Excalibur news release dated July 9th, 2026) to refine the Company's interpretation of the target.
Highlights from Rangefront
- Ground gravity survey completed: Approximately 20 square kilometres covered by a survey grid measuring approximately 6 km by 3.4 km, with stations spaced at 200 m intervals.
- Rangefront Fault and Splays: Results refine the interpretation of fault locations and displacement, helping identify structures that may have provided pathways for mineralizing fluids.
- Refining depth-to-bedrock: Interpretation of the gravity data is helping assess the thickness of cover along the Rangefront corridor and prioritize potentially shallow, concealed drill targets.
"The gravity survey was designed to help us understand what lies at the structural intersection between the primary Bellehelen fault zone and the Rangefront fault, as well as what lies beneath the cover at Rangefront," commented John Gilbert, CEO of Excalibur. "The results support our interpretation that this structural setting may have provided pathways for mineralizing fluids. Together with the alteration, geochemical and CSAMT data, the gravity results strengthen the rationale for prioritizing Rangefront within Bellehelen's broader portfolio of exploration targets and will help us refine where to focus drill testing."
Rangefront Gravity Survey
Rangefront lies approximately eight kilometres northwest of Spyglass Ridge, within the broader Bellehelen exploration corridor. Previous work identified extensive alteration and a multi-element soil anomaly associated with the Rangefront area, where exposed bedrock passes beneath younger gravel cover to the west.
As reported on July 9, 2026, CSAMT surveying identified a west-dipping resistivity discontinuity interpreted as a fault that may have influenced hydrothermal fluid movement. The gravity survey was subsequently undertaken to provide complementary information on subsurface geology and structures.
Thomas Carpenter, Consulting Geophysicist of Reno, Nevada, completed the survey in September 2026. The survey comprised 420 stations spaced at 200 m intervals across an area measuring approximately 6 km by 3.4 km. Measurements were collected using LaCoste and Romberg Model-G gravity meter number G-230. This meter has a proven record of excellent repeatability and low drift rates. The levels and sensitivity of the meter were checked prior to the commencement of the survey.
Of the 420 stations established on the Project, 9 stations (2.1%) were occupied twice to check the statistical accuracy of the gravity measurements. The gravity repeatability varied from +/- 0.000 to 0.047 mGal, with an average difference of 0.008 mGal.

Geological Interpretation and Target Development
The Company's integrated interpretation of the gravity survey and existing exploration data identifies a prominent gravity high associated with the Rangefront Fault. More subtle gravity features are interpreted to reflect subsidiary fault splays and the intersection with the Bellehelen Fault.
The gravity results are being evaluated alongside previously interpreted CSAMT resistivity data, geological observations and surface geochemical anomalies to refine potential drill targets. This work is helping the Company estimate depth to bedrock, evaluate potentially mineralized structures and geological horizons, and refine proposed drill locations.
Gravity and CSAMT surveys measure variations in the physical properties of the subsurface. Their interpretation does not establish the presence, grade or continuity of gold-silver mineralization, which would require drill testing.
Grant of Incentive Stock Options
The Company also announces that on October 19, 2026, it has granted 300,000 incentive stock options (the "Options") to a director of the Company, in accordance with the Company's Stock Option Plan. The Options are exercisable at a price of $0.105 per share for a period of five years from the date of grant and are subject to the policies of the TSX Venture Exchange.

About Bellehelen
Bellehelen encompasses a district-scale, 10-kilometre-long mineralized trend that historically produced an estimated 311,000 silver-equivalent ounces in the early 1900s1. Numerous historic workings are distributed along the entire length of this extensive corridor, highlighting a continuity of mineralization across multiple zones on the Property. Historical surface sampling returned high-grade assays of up to 11.25 g/t gold and 3,490 g/t silver1, confirming the presence of a fertile precious metal system. Broad soil anomalies, extensive vein networks and the results of the Company's recent drilling and geophysical programs demonstrate the potential for both structurally controlled higher-grade mineralization and broader zones of disseminated mineralization.
