 Vancouver, British Columbia--(Newsfile Corp. - July 29, 2025) - Prospector Metals Corp. (TSXV: PPP) (OTCQB: PMCOF) (FSE: 1ET) ("Prospector" or the "Company") is   pleased to announce that it has more than doubled the size of its   flagship ML Project in the Yukon ("ML").  It is also pleased to provide   an update to the ongoing drill program, with the first assay results   expected in the coming weeks.
 
 Rob Carpenter, Ph.D., PGeo.,   President, CEO and Co-Chairman of Prospector, stated: "Our pace of   drilling has exceeded our expectations while still being within our   approved budget. To date, we are currently 970m ahead of schedule. While   we continue to confidently spot new holes based on our real time  visual  interpretations of drill core, this fast drill pace has created a  back  log for sample cutting on site as well as sample analysis at our  assay  laboratory. We are systematically sampling the entire hole in  order to  capture a complete assay picture, and this large amount of  sampling is  also slowing down our pace for assay results. We are  expecting a large  amount of assays in the next few weeks and as a  result, we anticipate  our first release to encompass multiple holes  drilled at the Bueno, Java  and Rubble Targets."
 
 Drill Update
 
 A  total of  3600m meters over 20 holes have been completed on the ML  Project to date  (Table 1). This is 970m ahead of schedule.   Observations from the  ongoing drill program have confirmed the  mineralized corridor from Skarn  Ridge to Bueno is hosted within  north-northeast trending structural  zones with near vertical dips.   Previous interpretations of the targets  had not accounted for these  north-northeast trends, and as a  consequence, historical drilling did  not adequately test the structural  controls on mineralization.  Prospector is the first Company to recognize  the importance of  north-northeast trending structures and current  drilling is  successfully extending these zones along trend and to depth.

 Claim Staking
 
 Prospector   has recently expanded the size of the ML project through claim  staking.  Prospector owns these new claims 100% and are not subject to  any  third-party royalty. The size of the project has been increased  from  4,757 ha (47.57 km2) to 10,869 ha (108.69km2)  representing a  128.48% increase in the size of the project.  The project  now consists  of 552 mineral claims, of which 296 claims are newly  staked. The claims  were staked to cover new target areas generated  through analysis of  regional historical data, LiDAR and WorldView-3  remote sensing data, as  well as new concepts developed during the  ongoing 2025 drill program.
