New Copper Zones Discovered in Dominican Republic Gold Exploration

“Rock sampling in the Dominican Republic revealed copper zones with grades up to 1.2% Cu in recent gold exploration.”

Introduction: Unveiling Copper Mineralization in the Dominican Republic

Gold exploration in the Dominican Republic is entering a remarkable new phase as we uncover fresh copper mineralization zones in the Juan de Herrera project. On April 22, 2025, from Vancouver, B.C., Precipitate Gold Corp. announced the results from meticulous surface rock sampling techniques and trench analysis in the Centro Zone. This news release signifies not only the identification of new high-grade copper-rich targets but also outlines strategic drilling plans that fortify the Dominican Republic’s standing as a premier mining jurisdiction.

Our ongoing field exploration within this 100% owned property continues to demonstrate the unique marriage of gold discovery and copper resources, a hallmark of the region’s volcanic geology. These advances set the stage for future economic development, encourage further mineral property exploration, and spotlight the critical role of surface trench sampling, detailed soil sample analysis, and advanced geochemical-geophysical mapping.

The latest findings highlight how gold exploration in the Dominican Republic is leveraging modern science and logistics to open promising new mining frontiers, ultimately offering increased potential for drilling exploration targets and robust mining concessions within the region.

Project Overview: The Juan de Herrera Project and Its Strategic Significance

At the heart of these discoveries lies the Juan de Herrera Project, a wholly owned mineral property of Precipitate Gold Corp. This expansive concession comprises approximately 12,706 hectares in San Juan Province—strategically located adjacent to GoldQuest Mining’s Romero gold-copper project in the Upper Cretaceous-aged belt known as the Tireo Gold Formation. Over the past decade, nearly 5.0 million gold equivalent ounces have been delineated and advanced in this prolific terrain, setting a powerful precedent for continued exploration.

Our property’s unique geological context—rich in intermediate sulphidation epithermal and VMS (volcanogenic massive sulfide) styles—makes it an ideal environment for both gold and copper mineralization. Numerous historical and current findings from geochemical anomalies mining and soil sample analysis further establish Juan de Herrera as one of the Dominican Republic’s premier gold and copper projects, offering vast upside for investors, mining professionals, and local economic development alike.

The region’s drilling targets are not only delineated by extensive fieldwork but are being continually redefined by the latest rounds of surface rock sampling, trenching, and geophysical surveys.

Rock Sampling Techniques in Modern Mining Exploration

An essential component of our mineral property exploration is the rigorous rock sampling techniques utilized throughout the Juan de Herrera concessions. During our recent campaigns, surface rock samples and hand trench sampling were methodically collected across target zones, including the newly identified Centro Zone and the significant Southeast Zone.

To ensure reliable and reproducible results, all samples were bagged, sealed, and transported directly to the Bureau Veritas (facility) in Maimon, Dominican Republic for preliminary preparation procedures. The steps include:

• Drying and Crushing: Samples from rock and soil are dried, then crushed to over 70% passing 2mm mesh.
• Sample Splitting: Crushed material is split using a riffle splitter, producing a 250-gram sub-sample for further work.
• Pulverization: Sub-samples are pulverized to minus 200 mesh (74μm), forming finely ground pulps fit for analysis.
• Chemical Digestion: For multi-element examination, a 15-gram sub-split undergoes aqua regia digestion and subsequent multi-element ICP-ES/MS analyses.
• Fire Assay for High-Grade: Samples containing more than 2 g/t gold or 5000 ppm copper receive fire assay analysis, gravimetric finish, or even 4-acid digestion for selectivity and accuracy.

All analyses are performed at Bureau Veritas’s ISO 9001 accredited facility in Vancouver, Canada, with excess rejects and pulps securely stored for traceability. This meticulous workflow underscores the importance of proper preparation and analysis in mineral property exploration, lowering the risk of securities misreporting and enhancing the confidence of our findings.

Surface Trench Sampling Results: Centro Zone Highlights (Gold Exploration Dominican Republic)

In our latest surface trench sampling campaign within the Centro Zone—now a priority target in the Juan de Herrera project—we have achieved remarkable findings that underscore the mineral wealth of this volcanic terrain. Among the most outstanding interval results:

• Trench sampling yielded 4.4% copper and 0.3 g/t gold over 1.8 metres.
• This result was part of a larger mineralized interval: 1.6% copper and 0.2 g/t gold over 5.3 metres.
• A broader, lower grade interval was also confirmed: 0.4% copper and 0.2 g/t gold across 26.3 metres.

These findings are of special relevance when viewed alongside the 113 surface rock grab samples collected to date, which yielded values from nil to 2.0% copper and up to 2.6 g/t gold. Our sampling focused on andesite volcanic lithologies showing variable silicification and pyrite-chalcopyrite mineralization, a classic hint of productive copper-gold zones in geology.

The Centro Zone is located roughly 425 metres east of the existing Southeast Zone, where previous trenching produced up to 13.0% copper and 0.9 g/t gold in rock grab samples and trench sampling yielded 2.8% copper over 3.0 metres within a wider 8.0m section averaging 1.3% copper. These results build a strong case for both immediate and expanded drilling programs in the region.

Geochemical and Geophysical Anomalies: Data-driven Exploration

The success of our exploration hinges on state-of-the-art geochemical and geophysical surveys. Our crews have mapped and sampled across a trend of about 1.2 kilometres long by 100 meters wide, focusing on three robust gold-in-soil anomalies within the Centro Zone—each offering distinct mining potential.

These clusters coincide with:

• Strong resistivity high anomalies: Potentially signaling silica alteration indicative of mineralizing systems.
• Modest IP chargeability high anomalies: Suggesting zones of increased sulfide content—often correlated with copper and gold mineralization.

Combined with detailed rock sampling techniques and comprehensive soil sample analysis, our approach integrates robust field geology with high-resolution geochemical-geophysical mapping to pin down new drilling exploration targets.

The ability to consistently delineate such anomalies is what positions the Dominican Republic—and particularly San Juan Province—as a top-tier destination for major gold and copper mining concessions.
