Scottsdale, Arizona--(Newsfile Corp. - June 29, 2022) - TriStar Gold Inc. (TSXV: TSG) (OTCQX: TSGZF) (the Company or TriStar) is pleased to announce the start of a 2,500m expansion and exploration drilling program at its Castelo de Sonhos gold project. This core drilling is principally designed to test areas of higher-grade extensions to the Esperança South mineralization and has been developed by GoldSpot Technologies and TriStar's geological team.

"There is currently one core-rig at site and another one scheduled to arrive in a few weeks to help complete the 2,500m program quickly and efficiently." says Nick Appleyard, TriStar's President and CEO. "In our PFS announced late last year Esperança South (PFS Phase 1) produced approximately 150,000 ounces of gold per year, the aim of this drill program is to test the extensions of this mineralization. We anticipate reporting results on a regular basis."

Drill hole targeting
Drill holes have been located to test for the locations, or extensions of, gold-bearing channels. A high priority has been given to machine learning assisted proposed holes, derived from the integrated examination of mineralization and gold-hosting stratigraphy. Factors that have been taken into consideration include:

• Gold is dominantly within the quartz-conglomerate unit (or nearby/adjacent, in the hanging wall or footwall)
  
  
• Paleochannels are traced by local variance in 3D stratigraphy derived from machine learning geochemical analysis (chemostratigraphic modelling)
  
  
• Target soil anomalies within buffer of outcropping quartz-conglomerate unit are especially attractive -they represent historic drilling successes
  
  
• Areas with unexplained gold soil anomalies, down slope from outcropping quartz conglomerate, suggest gold bearing units in drainage at higher altitude
