Zonte Metals Extends Its Big K Gravity Anomaly on Its Cross Hills Copper Project and Receives a Grant From the Government of Newfoundland and Labrador

DARTMOUTH, NOVA SCOTIA - April 15, 2025 (NEWMEDIAWIRE) - Zonte Metals Inc. (TSXV:ZON)(XOTC:EREPF) is pleased to report the extension of the gravity anomaly at the Big K target on its Cross Hills Copper Project in Newfoundland and Labrador, marking the seventh large-scale anomaly discovered by the company.

Highlights from Nine Mile target:

- Discovery of two gravity anomalies within the target, extending the total length to 2.2km.

- The largest gravity anomaly measures 1400 x 600m and 840m deep.

- Above the anomaly, a bedrock copper showing returned 2.82% Cu and 10 g/t Ag.

- Gravity anomalies are coincident with copper-in-soil anomalies.

Terry Christopher, President and CEO, commented: "The recent gravity survey, which covered the southern extension of the previously discovered Big K target, identified two closely spaced anomalies extending over a 2.2 km strike length. These gravity bodies, located approximately 40 to 60 meters below the surface, coincide with Cu-in-soil anomalies and known bedrock copper mineralization. A previously discovered copper vein, which returned 2.82% Cu and 10 g/t Ag, was found at the surface above the gravity targets. It is postulated that this surface copper mineralization was pushed up through the capping rock from a deeper source. The strong correlation across all exploration techniques highlights the high-priority nature of this target."

The northern portion of the Big K target was previously defined through gravity, magnetics, structural analysis, IOCG-style alteration, and copper in bedrock and Cu-in-soil anomalies. Earlier work identified a drill-ready target approximately 1,500 meters long. However, additional soil sampling in 2024 extended the original soil anomaly further south (August 7, 2024). The recent gravity survey was conducted over this newly identified southern extension.

Results from the 2025 gravity survey identified two closely spaced gravity anomalies within a 2.2 km strike length. The larger anomaly measures 1,400 by 650 meters and extends to a depth of up to 840 meters. The second anomaly, located 140 meters to the south, has a generally spherical shape with a diameter of 650 meters. Both anomalies lie between 40 and 60 meters below the surface. Note, the anomalies become one when the 3D residual gravity is processed at 0.50 g/cc. A previously discovered high-grade bedrock copper showing, which returned 2.82% Cu and 10 g/t Ag, sits above the anomalies. This showing consists of a chalcocite vein cutting through a capping granite and is believed to have resulted from a fluid injection, possibly linked to the gravity anomalies below. The chalcocite vein, ranging from 2 to 8cm in width and 1.5m in length before merging into granite, was selectively sampled. Thus, the grab sample may not accurately represent the true underlying mineralization.

The Company has conducted numerous geophysical and geochemical programs over the target area. Among these, Mobile Metal Ion (MMI) and Soil Gas Hydrocarbon (SGH) soil sampling programs have been completed, both of which identified Cu-in-soil anomalies coinciding with the gravity signatures. The very southern portion of the target area has not been covered with SGH sampling. The Company may complete further sampling to bring this target to drill-ready stage.
