WOLF NEWS - ASSAYS VANCOUVER, BC-- Atna Resources Ltd. and YGC Resources Ltd. are pleased to report assay results from the initial 7 drill holes of the 1998 Wolf program. Significant widths of banded zinc, lead and silver massive sulphides were intersected in holes WF 98-24 and 25. In addition, hole WF 98-26, drilled 50 metres from WF 98-25, intersected 7.7 metres (true thickness) of massive sulphides indicating a continuation of this mineralization in an easterly down-dip direction (assay results are pending). Results from hole WF 98-16, which was drilled down-dip from the western edge of the deposit, suggest that the deposit thins in this area; high grade zinc massive sulphide mineralization was intersected 30 to 50 metres below the main deposit horizon showing potential for discovering additional deposits at a lower stratigraphic level. Results from hole WF 98-17, drilled to test the down-dip western part of the deposit, indicate that the deposit is displaced by a fault in this area, which is located approximately 400 metres down-dip from the surface. Hole WF 98-19, drilled below and west of WF 98-16, intersected the same fault as in WF 98-17, indicating that the fault has a southeasterly trend away from the deposit. Hole WF 98-18 tested for a southwesterly plunge of the thicker mineralization encountered in the discovery hole WF 97-07; it intersected 6.8 metres of higher grade massive sulphide mineralization. Holes WF 98-20 and 21 tested the area between holes WF 16 and 18 and intersected banded massive sulphides over moderate widths. Holes WF 98-22 and 23, drilled to test the up-dip area of the deposit, 175 metres northeast from discovery hole, intersected the sulphide horizon close to surface where extensive leaching of the sulphide mineralization has occurred. Hole WF 98-23 also was drilled beyond the Wolf Deposit horizon to test for stacked sulphide lenses in the stratigraphy. This hole intersected two lower massive sulphide zones of moderate grade and width, again indicating the possibility for discovering additional resources at lower stratigraphic horizons.

Follow-up drilling is currently underway on this new discovery. Drill results to date show that the Wolf Deposit has a strike length of 500 metres and a down-dip length of approximately 400 metres and is open for expansion; further drilling is planned. Several attractive targets characterized by coincident geochemical and geophysical anomalies have been identified on the Fox Claims, which cover the northwest extension of the favourable massive sulphide/barite horizon. These claims under option from Cominco Ltd. will be drill tested this season. Atna Resources Ltd. is a Canadian mineral exploration company with a track record for discovering significant massive sulphide deposits. Atna trades on the Toronto Stock Exchange under the symbol ATN and has a treasury of approximately C$17 million. **For a hard copy of the Wolf Project Diamond Drilling map, please call 1-800-789-2862. - 30 - For further information contact: Signed "Peter R.
