White Rock Minerals update on VMS project

White Rock Minerals Ltd announced that orientation geophysics at its 100% owned high-grade zinc VMS project at Red Mountain in Alaska has confirmed that the Dry Creek massive sulphide mineralisation is coincident with strong conductivity anomalies that are identified using both the CSAMT geophysics exploration tool (see Figure 1 in link below) and time domain electromagnetics geophysics. This successful orientation work allows White Rock to progress with confidence in applying the more rapid acquisition of CSAMT data across priority target areas, prior to drill testing.

1. Drilling to test for down dip extensions at the Dry Creek zinc VMS deposit intersects massive sulphide mineralisation at the Discovery lens,

2. Drill hole DC18-79 intersects 6.1m with abundant visual zinc and lead mineralisation,

3. Orientation geophysics confirms strong conductivity anomalies are coincident with massive sulphide mineralisation,

4. CSAMT geophysics surveys have now commenced across other high priority target areas ahead of drill testing and potentially future discoveries.

At Dry Creek, the first drill hole (DC18-79) at the Discovery zone targeted the down-dip extension of the Resource. Drilling intersected massive sulphide mineralisation with abundant sphalerite (zinc), pyrite and galena (lead) from 230.6 to 236.7 metres (6.1m) downhole (estimated true width of 3.9m) (see Figure 2 in link below). This hole is some 60 metres from the nearest hole (DC97-26).

Highlights the coincidence of the CSAMT conductivity anomaly with massive sulphide mineralisation intersected in historic drill holes at the Discovery lens. Drill hole DC18-79 intersected the massive sulphide zone of abundant sphalerite and galena in the core of the CSAMT anomaly. The coincidence of conductivity and massive sulphide mineralisation rich in sphalerite provides confidence in applying the CSAMT technique to define other targets for drill testing in new prospective areas prioritised by favourable geological observations and anomalous surface geochemistry.

Mr Matt Gill MD & CEO said that "We are delighted with the results of the orientation geophysics. The stark conductivity anomaly results seen and their coincidence with known massive sulphide mineralisation gives White Rock a powerful exploration tool with which to identify new targets for drill testing, hopefully leading to resource expansion and the discovery of new deposits. Further, this latest drill hole intercept of massive sulphides supports our belief that there is further potential for the discovery of more high-grade VMS mineralisation and that this resource is also open down-dip."
