Nexcel hires Xcalibur for Burnt Hill geophysical survey

Executive Summary

• Nexcel Metals Corp. has engaged Xcalibur MPH (Canada) Ltd. to conduct a high-resolution HeliTEM airborne electromagnetic (AEM) and magnetic survey at its Burnt Hill tungsten project in New Brunswick, Canada.
• The survey is a critical preparatory step for the company's planned initial drill program in 2026, aimed at identifying deep conductive bodies and refining subsurface targets for tungsten mineralization.
• Mobilization for the survey is anticipated for approximately April 1, 2026, with results to be integrated into the exploration workflow to define high-priority drill targets.

  • Time-domain electromagnetic data sets.
  • Magnetic data and derivatives.
  • GIS-compatible data sets and databases.
  • Quality control products and flight path data.
  • Final processed geophysical products suitable for interpretation and targeting.
• Data Usage: To generate conductivity models and drill targets supporting Nexcel's phase 1 exploration program.
• Qualified Person: Francis Newton, PGeo, consultant and qualified person under National Instrument 43-101 (not independent of the company).

Notable Quotes

• "Engaging Xcalibur to complete a high-resolution HeliTEM airborne survey is a key milestone for Nexcel as we advance Burnt Hill into its next phase of exploration... This survey is specifically designed to identify deeper conductive targets that have not been previously tested, positioning us to unlock additional tungsten mineralization at depth." — Hugh Rogers, Chief Executive Officer of Nexcel.
