VANCOUVER, British Columbia--(BUSINESS WIRE)--May 30, 2001

Three drill holes, totaling 1,338 feet, tested for the down-dip extension of polymetallic mineralization beneath the old Lone Pine Mine workings and a parallel TEM geophysical anomaly. Narrow sections of semi-massive to disseminated sulphides mineralization were intersected in sericitic and iron carbonate altered rock. LP01-1 intersected 4.1 ft. of 0.18% Cu, .05% Pb, 0.7% Zn, 7.3 g/t Ag and 0.5g/t Au. No significant values were intersected in LP01-2. LP01-3 intersected 5.6 ft. of 0.4 %Cu, 0.4% Pb, 0.5% Zn, 47.5g/t Ag and 2.2g/t Au. Thinning of the mineralization below the old workings may be the result of complex folding; carbonaceous epiclastic sedimentary rocks intersected in the hanging wall are the probable cause of the TEM anomaly. More detailed geological mapping and structural interpretation will be necessary to determine if the property warrants further drilling.

During the course of this program Atna examined other volcanogenic massive sulphides (VMS) prospects in the same belt of rocks that host the Iron King Mine and Lone Pine prospect of central Arizona. Several of the properties have been examined, mapped and sampled by major mining companies. Atna staked mineral claims over and along strike from a VMS deposit that had limited mining and exploration development carried out in the early 1900s. The altered mafic and felsic host rocks extend for more than 4,800 feet along strike from a vertical shaft and dump. Banded massive sulphides and siliceous iron formation are hosted in pyritic quartz sericite schists.

The VMS prospect and adjacent claims have considerable exploration potential. Assay results from selected dump samples of banded massive sulphides returned high-grade polymetallic values up to 10% Cu and 6.6 g/t Au. The old mine site and adjacent claims and will be mapped and sampled to outline targets for drill testing.

Atna is a well financed mineral resource company focused on acquiring projects with potential for near term cash flow and exploring properties that have the potential for significant discoveries.
