Vancouver, British Columbia - (March 9, 2026) - Stockworks Gold Inc. (TSXV: STW) ("Stockworks" or the "Company") is pleased to announce it has received assay results from a recent geochemical sampling program at its 100% owned, road accessible Pirenópolis gold project located in the mining-friendly state of Goiás, Brazil. Results include high-grade stream sediment samples of up to 6.38 ppm gold (6.38 g/t 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 kilometers 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 October 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 1.64 ppm to 0.424 ppm gold in the 2 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 3 areas where the gold in stream sediments may be originating from (see attached figure 1). 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 October 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 bedload drop off. This regional structural feature is also seen in the government regional airborne magnetic survey and trends for greater than 30 km continuing off the government survey in both directions. A third geophysical feature, further up stream in bedload 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 2 kms further upstream.
These results represent a significant advancement in the systematic targeting of bedrock gold sources at Pirenópolis 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 Pirenópolis Gold Project
The 40 km² Pirenópolis 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 1800's however, the hard-rock source(s) of the alluvial gold has never been located.
The Pirenópolis 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 Pirenópolis 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.
Goiás, 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 2 mm to obtain approximately 1.5-2.0 kilograms of sample material. Samples were delivered via chain-of-custody to ALSGlobal's laboratory in Goiânia, Goiás. ALSGlobal 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 ALSGlobal's internal QA/QC procedures. At the lab, each sample was screened to 125 um (ALS code SCR-36). Twenty-five grams was then taken from the screened material and analysed by aqua regia digestion, and ICP-MS finish ultra-trace 51 elements (ALS code AuME-TL43). The unprocessed sample remaining from the screening was then added back to the original sample and re-homogenized. This master sample was then split to 1 kg and analysed 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 1 kg 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 to the 1.0 kg 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.
