Tristar Discovers New Gold-Bearing Zones at Castelo de Sonhos

SCOTTSDALE, Ariz., May 08, 2018 (GLOBE NEWSWIRE) -- TriStar Gold Inc. (the “Company” or “TriStar”) (TSX.V:TSG) is pleased to announce that the 2018 exploration campaign at its Castelo de Sonhos gold project (“CDS”) has identified two new gold-bearing targets.

Mr. Nick Appleyard, President and CEO, commented: “Our goal with the current exploration program is to continue to expand the mineral resource at Castelo de Sonhos, so we’re very pleased to have confirmation of gold mineralization in outcrops that add more than three kilometers to the known strike length. It is great to see that we’ve been able to leverage the strong geological understanding developed by our Brazilian team and our consultants. At the same time that we’re identifying new targets, we’re also improving our resources and confidence in areas that have previously been drilled, filling in gaps and extensions. With the early successes in this year’s program, we’re looking forward to updating the resources and completing a preliminary economic assessment.”

Soil sampling

Dr. Rael Lipson of TriStar’s technical advisory group recommended extending the existing soil sampling grid into new areas since, elsewhere on the property, anomalous gold in surface samples has consistently been a reliable indicator of gold mineralization at depth. The sampling, descriptive and analytical work to follow up on this recommendation is now complete, and reveals two new targets (see Figure 1) that now need to be drill tested.

2018 New Discovery Zone (“NDZ”)

The NDZ conglomerate outcrops on the western edge of the property and has a mapped strike length of approximately 2 km.  Ten soil sampling lines at 200m spacing have now confirmed that the NDZ is highly anomalous in gold, with all lines showing a distinct continuous zone of mineralization coincident with the conglomerate.

2018 Upper Conglomerate Zone (“UCZ”)

The UCZ conglomerate was initially recognized by Dr. Rael Lipson in 2016 as an additional band of conglomerate that sits in the arenite above the main conglomeratic band at CDS.  Four sampling lines were strategically located to cross the UCZ; assays from soil samples on these four lines encountered anomalous gold grades on every line. The size of this secondary band of mineralized conglomerate has not yet been fully established, but the mapping and sampling work to date confirms more than a kilometer of strike length for this previously unrecognized and undrilled target.

Drilling

As of May 4, a total of 26 reverse circulation (“RC”) for 3,020m and 8 core holes for 960m have been completed (see Figure 1).  The RC drilling program includes infill drilling in Esperança Center (now complete) and Esperança South (yet to be done), and broad definition drilling in Esperança East (underway). The RC rig will finish the first round of Esperança East holes in May and will then move to Esperança South to follow up on high-grade intervals previously encountered there and still open in several directions. Following analysis of the results, TriStar plans to continue RC drilling, to maximize the data available for expanding mineral resources in the next resource update. The man-portable core rig targeted resource extensions on steep slopes; that program is now complete, and the core rig has been demobilised.

Following completion of RC drilling, TriStar will log the RC holes using the same petrophysical probes and optical televiewer that provided valuable data in the 2017 drilling program and that improved understanding of local continuity directions for resource estimation.

For the nine holes for which assays are now available (all RC holes in Esperança Center and East), all show one or more significant intervals. Due to the large number of drill holes this year, both completed and planned, and the expectation that the rate of drilling will increase, TriStar will use its website to make available detailed summaries of drill hole locations and significant intervals; a file has been added to the CDS project page of the company website (www.tristargold.com) with a complete list of significant intervals for the project.  This information will be updated regularly, allowing investors direct access to complete and up-to-date information whenever they choose.

Full evaluation of the drill holes will be possible when drilling has been completed in each zone and when the OTV and petrophysical logging are available. With the partial information currently available, the assay values are consistent with expectations established by previous drilling, both in terms of grade and thickness.

Assay methods, quality assurance and quality control (QA/QC)

All soil samples have been analyzed by fire assay of a 50g aliquot of material taken from the “A” horizon. In 2018, all drill hole samples are analyzed using a Leachwell analysis of 1kg of material taken from either ½ core in diamond drill holes or ¼ of the chips in reverse circulation holes. Samples are transported by truck from site to the ALS lab in Goiania, 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.
