Atna Resources Ltd. is pleased to report excellent assay results
from its Phase 1 drilling program (10 holes totaling 1437 metres)
on the San Antonio I Concession in the Dominican Republic. The
drilling program was designed to test, at shallow depths, several
areas of the property where coincident IP chargeability and
geochemical soil anomalies were underlain by a favourable belt of
host rocks.
La Parcela Zone
Drill hole SA 99-01 was collared to test the favourable contact
60 metres down-dip from a 0.3 metre zinc-rich massive sulphide
intersection in SJ-4 (previously drilled in 1990). SA 99-01
intersected 3.4 metres grading 5.9% copper, 3.5% zinc, 0.1% lead,
85.7 g/t silver and 2.27 g/t gold in hanging wall rocks and a 1.4
metre section of massive sulphides grading 2.4% copper, 10.5%
zinc, .01% lead, 142.7 g/t silver and 1.10 g/t gold at the
contact between hangingwall sediments/tuffs and highly altered
pyritic, quartz-sericite schists. Hole SA 99-02, drilled 100
metres northwest of SA 99-01, intersected 3.1 metres of massive
sulphide grading 3.4% copper, 8.6% zinc, 0.1% lead, 185.2 g/t
silver and 1.38 g/t gold (reported March 12, 1999). This
intersection included 1.1 m grading 6.8% copper, 16.6% zinc,
0.30% lead, 462.5 g/t silver and 1.47 g/t gold. These values
confirm the potentially high-grade nature of the base and
precious metal mineralizing system. Hole SA 99-03, collared 100
metres southeast of SA 99-01, intersected 1 metre of massive
sulphides grading 1.2% copper, 2.1% zinc, 0.1% lead, 69.8 g/t
silver and 1.87 g/t gold. Hole SA 99-04, collared 200 metres
northwest of SA 99-01, intersected 2.7 metres of massive
sulphides grading 2.2% copper, 4.1% zinc, 0.1% lead, 20.9 g/t
silver and 1.83 g/t gold. SA 99-10 was drilled to test 70 metres
below the SA 99-02 mineralization; it intersected strong
stringer-type copper and zinc sulphides in highly altered
footwall rocks. Hole SA 99-09, drilled 1 kilometre to the
southeast of the La Parcela Zone, encountered similar altered
footwall rocks containing disseminations and stringers of copper
and zinc sulphides. The La Parcela massive sulphide
mineralization appears to be continuous over a strike length of
400 metres, has been intersected to a depth of 130 metres and is
open in most directions.
Barite/Jasper Zone
Holes SA 99-05 and 06 tested an area 1.5 kilometres southeast
from the La Parcela Zone. Gossanous, banded baritic rock in
sub-crop was discovered adjacent to an area of large jasper
boulders. Assay results of grab samples from these banded
gossanous rocks showed some of the highest precious and base
metal values on the property. Results from the drilling and a
more detailed appraisal of the area suggest that the holes were
not orientated in the correct direction to test the depth extent
of mineralization in this attractive target.
Copper Zone
Hole SA 99-07 tested a surface oxide copper showing 2 kilometres
southeast, along trend, from the La Parcela Zone. The drill hole
intersected 1.9 metres of 1.2% copper, 15.8% zinc, 0.03% lead,
24.0 g/t silver and 1.31 g/t gold. Follow-up hole SA 99-08
(drilled 100 metres down-dip) intersected 1.2 metres of massive
sulphides grading 1.3% copper, 5.3% zinc, 0.01% lead, 16.3 g/t
silver and 1.48 g/t gold. This new discovery is significant as it
possibly represents a separate centre of high grade
mineralization associated with a thickening of rhyolitic host
rocks in this area.

Following compilation of all results, including the outstanding
assays of disseminated and stringer mineralization in drill core,
additional geochemical soil surveys, detailed geological mapping
and consultants reports, a follow-up drill program will commence.
Overall the results from the first phase drilling suggest that
the holes might have intersected the up-dip edge of a base and
precious metal rich massive sulphide deposit.
