STOCKWORKS GOLD RECEIVES HIGH-GRADE GEOCHEMICAL RESULTS FROM THE
PIRENOPOLIS GOLD PROJECT, BRAZIL
Stockworks Gold Inc. has received assay results from a recent geochemical sampling program at its 100-per-cent-owned, road-accessible Pirenopolis gold project located in the mining-friendly state of Goias, Brazil. Results include high-grade stream sediment samples of up to 6.38 parts per million gold (6.38 grams per tonne Au).
This detailed stream sediment sampling campaign, conducted in December, 2025, was designed to follow up on previously collected regional anomalous gold geochemical samples. The earlier samples returned 4.7 ppm and 3.9 ppm gold in stream sediments from two parallel drainages 1.0 to 1.5 kilometres apart. In addition, during this earlier work, one of the drainages returned a mineralized quartz float boulder, which assayed 0.8 g/t gold (see news release dated Oct. 16, 2025).
The December, 2025, work collected 31 stream sediment samples on the property, 26 of which were closely spaced, continuing up the two parallel drainages on the eastern claim from the previous anomalous samples to the point where the streams diminished and the sediment load was no longer present. Five samples were collected on the western claim drainages in reconnaissance-style sampling for initial evaluation.
Results from this work have returned an assay of 6.38 ppm gold as well as four additional samples ranging from 0.424 ppm to 1.64 ppm gold in the two streams. The sampling program has successfully traced the earlier gold anomalies up both streams closer to their potential bedrock sources. The company interprets these results as having defined three areas where the gold in stream sediments may be originating from. Refer to "Quality assurance/quality control" below for details on analytical procedures related to the anomalous results.
These cut-off areas have compelling coincident geophysical features interpreted from the recently completed low-level, high-resolution drone airborne magnetic survey conducted last October (see news release dated Oct. 16, 2025). There is an apparent northeast-southwest structural feature that cuts across both north-draining streams and coincides with the gold in the stream bed load drop-off. This regional structural feature is also seen in the government regional airborne magnetic survey and trends for greater than 30 kilometres continuing off the government survey in both directions. A third geophysical feature, further upstream in bed load termination, is interpreted as a potential intrusive body.
The western claim is also showing initial indications of potential bedrock gold source mineralization with two reconnaissance samples in a single drainage returning 0.133 ppm gold and increasing to 0.216 ppm gold two kilometres farther upstream.
These results represent a significant advancement in the systematic targeting of bedrock gold sources at Pirenopolis and establish multiple defined areas for follow-up exploration and potential drill targeting. The company is also eager to advance the recent positive reconnaissance-style results on the western claim with anticipation of swiftly developing specific gold-in-stream cut-off locations as was recently done on the eastern claim.
About the Pirenopolis gold project
The 40-square-kilometre Pirenopolis gold project is an early-stage project encompassing two parallel stream catchments with highly anomalous gold in sediment samples and a float boulder. The region experienced a placer gold rush in the 1700s and 1800s; however, the hard-rock source of the alluvial gold has never been located.
The Pirenopolis gold property occurs in the same geological belt as the Paracatu gold mine, also located in Brazil, which is Kinross Gold Corp.'s largest operation globally. The Pirenopolis gold project is interpreted as an orogenic gold target with features similar to Paracatu, including being hosted by similar geological rocks and having regional tectonic structures transecting the property as observed in airborne geophysics.
Goias, the third-largest mining state in Brazil, has several operating gold mines, including Serra Grande by Anglo American, Chapada (copper/gold) by Lundin Mining and Pilar Gold's PGDM complex, which consists of four mines. The company sees this as an opportunistic, low-cost entry point to the country of Brazil, a nation of vast mineral wealth.
Quality assurance/quality control
The December, 2025, stream sediment samples were collected by sieving sediment to minus two millimetres to obtain approximately 1.5 to 2.0 kilograms of sample material. Samples were delivered by chain of custody to ALS Global's laboratory in Goiania, Goias. ALS Global is an independent ISO 9001 and ISO/IEC 17025-certified geochemistry laboratory. The lab submits internal standards, duplicates and blanks, and all of these are reported within their expected limits. The company relied on ALS Global's internal QA/QC procedures. At the lab, each sample was screened to 125 micrometres (ALS code SCR-36). Twenty-five grams were then taken from the screened material and analyzed by aqua regia digestion and ICP-MS finish ultratrace 51 elements (ALS code AuME-TL43). The unprocessed sample remaining from the screening was then added back to the original sample and rehomogenized. This master sample was then split to one kilogram and analyzed by bulk leach extractable gold (BLEG) (ALS code Au-AA12), in which the sample undergoes a cyanide bottle-roll leach with an AA finish. Sample PRN011SS did not contain one kilogram of sample for the Au-AA12 analysis, so Au-AA11 was used, which is the same procedure as Au-AA12, but with 0.5 kg of sample material. This sample assayed 0.1395 ppm Au by BLEG, and the company believes this is representative and comparable with the 1.0-kilogram sample process for the purposes of interpretation as it is not in the highly anomalous category. For the anomalous samples referred to in this news release from the December, 2025, campaign, the 6.38 ppm Au and 1.64 ppm Au assays were BLEG analyses. The remaining three noted were by ICP-MS analysis.
