Stockworks Gold Commences Follow up of High-Grade Gold Stream Sediment Anomalies at the Pirenopolis Project, Brazil
The fieldwork is the project's first systematic effort to locate the bedrock sources of its stream-sediment gold anomalies.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
Stockworks Gold (STWGF) has begun soil sampling at its Pirenópolis gold project in Brazil to investigate stream-sediment gold anomalies.
Earlier samples from two parallel drainages 1.0 to 1.5 kilometers apart assayed up to 6.38 ppm gold (6.38 g/t). Follow-up sampling narrowed the potential source area, and a quartz boulder from the area assayed 0.8 g/t gold. The survey will cover ground alongside and between the streams. A separate anomaly, with assays up to 0.943 ppm (0.94 g/t gold), is also being surveyed. The interpreted source area overlaps a feature identified by a completed drone magnetic survey. Stockworks expects the soil results and magnetic data to define targets for its first drilling campaign; the bedrock source has not been established.

Vancouver, British Columbia--(Newsfile Corp. - September 28, 2026) - Stockworks Gold Inc. (TSXV: STW) (OTCQB: STWGF) (FSE: 4XO1) ("Stockworks" or the "Company") is pleased to announce it has commenced detailed soil geochemical exploration activities at its
Stockworks has begun a detailed soil geochemical survey following up on recently received significant gold values from stream sediment samples which returned assays of up to 6.38 ppm gold (6.38 g/t Au) (see news release March 9, 2026). The survey is designed to trace the source of the stream sediment samples and define priority drill targets on the project.
The previous stream sediment sampling programs returned highly anomalous gold values in two parallel drainages 1.0 to 1.5 kilometers apart. Follow-up sampling in both drainages successfully narrowed the potential source area, as anomalous gold values persisted upstream before abruptly terminating. This pattern suggests the bedrock source lies within the immediate upstream catchment area. In addition, a previously sampled quartz boulder from this area returned 0.8 g/t gold.
The soil sampling program now underway will collect samples in a detailed grid pattern both laterally and between the two streams with the goal of identifying an area of elevated gold-in-soil and/or associated pathfinder elements which are often associated with gold deposits. The interpreted source area also coincides with a large regional-scale magnetic feature identified from the Company's recently completed high-resolution, low-level drone magnetic survey (see news release October 16, 2025). The magnetic feature is indicative of a fault or shear zone. These types of regional tectonic structures can act as conduits for mineralizing fluids.
Elsewhere on the property, a second anomalous gold in stream anomaly has been identified with assays up to 0.943 ppm (0.94 g/t gold). The second anomaly exhibits a different geochemical signature than the primary target area, suggesting it may represent a separate style or source of gold mineralization. Stockworks is also conducting a soil geochemical survey at this anomaly.
Concurrent to the geochemical campaign, the Company will also be prospecting the drainages for additional mineralized float boulders and cobbles particularly in the vicinity of the 6.38 g/t gold stream sediment sample.
The current program represents the first systematic effort to define the bedrock source of multiple high-grade stream sediment gold anomalies on the property. Results from the soil survey, integrated with recently completed high-resolution drone magnetic data, are expected to define priority drill targets for the Company's inaugural drilling campaign.
The Pirenópolis gold project is an early-stage exploration property encompassing two parallel stream catchments that host significant gold-in-sediment anomalies, as well as a gold-bearing quartz float boulder. Furthermore, regional airborne geophysics by the government indicates an interpreted large-scale magnetic structural break cutting across the property upstream of the anomalous samples. The Company's high-resolution drone magnetic survey adds further detail to this in identifying specific interpreted features which may be associated with mineralization.
The region experienced a placer gold rush in the 1700s and 1800s, however, the hard-rock sources of the surrounding rivers' alluvial gold have never been located.
The property occurs within the same regional geological belt as the Paracatu gold mine, Kinross Gold Corp.'s largest operation globally. While similar geology does not guarantee mineralization, the project shares key characteristics including host lithologies and regional-scale structural features.
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.

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
What gold values did Stockworks Gold find in stream sediments at Pirenópolis?
Earlier stream-sediment samples assayed up to 6.38 ppm gold (6.38 g/t) in the primary target area. Samples from a separate anomaly assayed up to 0.943 ppm (0.94 g/t gold).
Why is Stockworks Gold surveying a second Pirenópolis stream anomaly?
The second anomaly has a different geochemical signature from the primary target area. Stockworks says this suggests it may have a separate style or source of gold mineralization.
What other fieldwork is Stockworks Gold doing at Pirenópolis?
Alongside the soil surveys, Stockworks plans to prospect the drainages for additional mineralized float boulders and cobbles, particularly near the stream-sediment sample that assayed 6.38 g/t gold.
