TRISTAR GOLD - CORPORATE UPDATE
Tristar Gold Inc. has provided an update on advancements in the work at the Castelo de Sonhos gold project in Para state, Brazil. TriStar is 100% focused on attaining the Licenca Previa (LP), or Preliminary Licence, the main environmental licence in the 3-step Brazilian mine permitting process. TriStar's Environmental Impact Assessment (EIA) and LP application were submitted in July of 2022, and assuming current timeline estimations are correct, we anticipate approval in the third quarter of 2023.
Mr. Nick Appleyard, CEO, stated, "The TriStar team are doing an outstanding job in maintaining open and transparent communication channels with the relevant state of Para authorities."
Government Relations and Environmental PermittingWith the inauguration of the new administration in Brazil, the TriStar team met with the regulators at the Environmental Secretariat (SEMAS) of Para State in Belem to confirm the status and timelines for receipt of the LP. The SEMAS licensing team informed us that the Castelo de Sonhos project is at the head of the line for EIA review. They remain committed to a technical site visit in March 2023, which is the next major milestone event, to review our environmental management and social engagement practices, and confirm the findings of the EIA.
SEMAS has informed TriStar that they anticipate an in-person public hearing in the village of Castelo de Sonhos, with the availability of virtual participation from municipal and other stakeholders. The TriStar team continues to prepare all engagement-related activities and prepare all technical requirements to ensure a successful hearing.
In anticipation of likely requirements for the next stage of permitting, TriStar has already advanced work on cave relevance studies and will be initiating detailed archeological studies.
Community Engagement and TransparencyThe TriStar team continues to engage with key stakeholder groups in both the areas of direct and indirect impact of the project, focusing on sharing detailed project information, listening and responding to questions and concerns, discussing timelines and potential future events. The aim is to prepare the local communities and key stakeholders for the public hearing, which will follow the SEMAS site visit. Our engagement activities focus on multiple parties including the municipality, sub-district businesses, small-scale entrepreneurs, landowners, schools and civil society organizations.
TriStar partnered with local village shops and stores for the delivery of Christmas hampers of vital supplies to families over the holiday season. We continue to identify opportunities to partner with government and civil society to support the well-being of local families-in-need specifically in the areas of health and education.
Environmental ManagementDaily environmental training and awareness initiatives have been developed at site by our internal team. Environmental management is focused on a continual improvement model, with current upgrades underway in the areas of solid waste management, recycling, treatment of effluents, power generation and potable water systems.
We continue with the sourcing and planting of native vegetation seedlings and the extensive rehabilitation of drill pads as well as helping to repair surrounding areas affected by the devastating impacts of seasonal wildfires.
LandWe have received confirmation from the National Institute of Colonization and Agrarian Reform (INCRA) that all land within the Directly Affected Area (ADA) of the project are federally administered, and that there are no known encumbrances to project development.
Community Investment & PartnershipsAs part of our commitment to building lasting partnerships in support of the development priorities of local stakeholders and communities, we are grateful to be partnering with the Altamira Municipality's Education Secretariat in the construction of an upgraded elementary school in the village of Esperanca IV. This is the closest village to the project area, and we believe this important partnership will have lasting positive impacts for generations of families to come.
DrillingTriStar completed a 2,500m drill program in October of 2022, and gold assay results have been received for 25 of the 26 drill holes (CSH-22-604 is still pending) and five drill holes are still waiting for multi-element geochemistry.

Results can be summarized according to the various defined aims of the program as:
ExplorationGold assay results have been received for 20 drillholes that were looking for possible extensions to the reefs around Esperanca South. The most promising results were in the southernmost drill hole CSH-22-577 (azimuth 140degree, dip -60degree, total depth 80m) which returned 3m @ 1.72 g/t gold (20 to 23m downhole), which is a good indication that the mineralization continues to the south.
The drill holes aimed at longer range extensions generally failed to intersect meaningful mineralization, although the easternmost drill hole, CSH-22-610 (azimuth 0degree, dip -90degree, total depth 150m) intersected 7m @ 0.67 g/t gold (3 to 10m downhole) including 2m @ 1.66 g/t gold (8 to 10m downhole). The shallow depth of mineralization and the fact the hole is located nearly 1km to the east of known mineralization makes this an interesting intercept worthy of follow-up. The westernmost drill hole CSH-22-609 (azimuth 0degree, dip -90degree, total depth 200m) did not have any significant results, although until we receive and analyze the geochemistry results, we will not be able to confirm if the hole reached its target.
The true width of the mineralized intersection quoted is between 85 - 100% of the downhole drill indicated width.
Condemnation DrillingFour drillholes, CSH-22-578/600/605/613, were designed to check for possible mineralization trending towards or underneath proposed waste dumps. None of these drill holes returned meaningful grades, so although this is not a definitive condemnation program it is a good first indication that the sites selected for the rock waste dumps at Esperanca South appear to be appropriate.
Twin holes - Reverse Circulation v CoreDuring this recent drill campaign, one core drill hole was drilled as a twin of a pre-existing reverse circulation (RC) hole, with the aim being to confirm that the RC drilling process does not impact the reliability of sample quality by imparting a systematic bias. TriStar has drilled six twin holes during previous campaigns, with multiple interceptions showing indications of a higher grade in the core assays.
Drill hole CSH-22-611 was twinned against old RC hole RC-19-392, drilled in 2019. Hole 392 had three low-grade mineralized zones as shown in Table 1 below. Hole 611, drilled recently, intersected the same zones, showing good repeatability of mineralization, but demonstrated higher grades in each zone. TriStar will resubmit the samples for Leachwell analysis in order to properly align grade comparisons. In general, Leachwell analysis has a higher precision than fire assays; due to the mass of the analyzed material being approximately 20x larger in a Leachwell assay than the 50g aliquots analyzed in a conventional fire assay procedure. The results presented in Table 1 show the preliminary comparison between the two holes, located 5m apart in Esperanca South.

Qualified PersonAlan Lambden (P.Geo.), project geologist for TriStar and the Qualified Person for the technical information presented in this press release, has approved its publication.
Assay methods, Quality Assurance and Quality Control (QA/QC)All drill hole samples are analyzed using a fire assay analysis of the chips collected in RC holes. Samples are transported by truck from the site to the ALS preparation lab in Brazil where they are dried, crushed, pulverized and packaged for shipment to the ALS analytical lab in Lima, Peru.
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.
