June 4, 2020 - TriStar Gold Inc. (the Company or TriStar) is pleased to announce the receipt of assays from 79 infill drill holes for 7,428m of drilling for the prefeasibility study at Castelo de Sonhos. Additionally, target generation work by GoldSpot Discoveries outside of the PFS area remains on track for completion of initial scope of work later this month. Phase one of this machine learning driven exploration program is anticipated to result in a combination of drill-ready exploration targets and recommendations for additional work to better validate and define the targets.
Highlights from the assays received this month include:
- 22m @ 2.5g/t from 85-107m in RC-20-457, includes 2m @ 20.4g/t from 85-87m
- 10m @ 1.3g/t from 32-42m in RC-20-459
- 4m @ 2.5g/t from 60-64m in RC-20-468
- 10m @ 2.2g/t from 21-31m in RC-20-479
- 10m @ 3.2g/t from 51-61m in RC-20-513
- 8m @ 6.9g/t from 70-78m in RC-20-524
All assays for the RC drilling completed to date are now in hand. A full table of results and drill cross-sections can be found on the Company website at www.tristargold.com. True widths are approximately 90% of the downhole lengths reported above.
“We are very pleased with these results, which include both higher grade intervals and significant thicknesses. Figure 1 shows how we are now seeing higher-grade continuity between drill holes that will aid in modeling and help target further drilling. With most of the resource drilling now complete the next step is the geological interpretation and modeling, this will be completed once our consultants can safely travel to the project” says Nick Appleyard, TriStar’s President and CEO. “We anticipate reaching the end of the initial scope of work with GoldSpot Discoveries soon and plan to aggressively test the new targets as soon as possible thereafter. This will most likely include both RC and core drilling possibly aided by additional data collection such as portable XRF and geophysics”.

The exploration work outside of the PFS area is focused on analysing remote sensing data over the CDS area, including magnetic signatures, radiometric data, topographic variation, and mineral abundance. These data are being variously combined to produce geologically meaningful data stacks. In turn, areas with known mineralization (e.g. from drilling or surface sampling), are used to identify the characteristic signature of rocks proximal to gold. As more data stacks become available, machine learning models are trained to look for similar gold-coincident signatures elsewhere on the property.

All drill hole samples are analyzed using a fire assay analysis of the chips collected from the RC holes or core from diamond holes. Any sample that returns greater than 0.1 g/t gold is automatically submitted for a duplicate fire assay analysis and the average grade is used. Samples were transported by truck from the site to the ALS preparation lab in either Goiania or Belo Horizonte, Brazil, where they were dried, crushed, pulverized and packaged for shipment to the ALS analytical laboratory in Lima, Peru, Vancouver, Canada or Loughrea, Ireland.
The ALS preparation and analytical labs are accredited to ISO 17025:2005 UKAS ref 4028, and have internal QA/QC programs for monitoring accuracy and precision. In addition to this, TriStar uses standards, blanks and field duplicates in an external QA/QC program to provide independent monitoring of laboratory analyses.
