The San Antonio property was the focus of both historic small-scale
underground mining at the turn of the century and a small surface excavation
which was completed within the past 20 years. The surface excavation
consists of a cut approximately 110 metres long, 5-10 metres wide and 10-30
metres deep. The material from the excavation was placed on heaps for
leaching with the higher grade material trucked offsite for processing.
Recent bulk sampling by HDG of the material on
one of the old leach pads returned average values of 1.8 g/t gold and 35.3
g/t silver. Bulk sampling of a smaller pad, which
does not appear to have been subjected to leaching, returned average values
of 3.1 g/t gold and 40.4 g/t silver.
While the Sonora Gold Belt is recognized as a
world-class gold and silver mining region, there has been little to no
modern exploration within 80 km. of the Company’s San Antonio gold project.

Sample widths of “vein material” are
interpreted to be approximately true widths of the mineralization sampled,
whereas other listed samples are interpreted to be part of a larger
mineralized interval limited by exposure and so widths may not be
representative of the true width.
HDG sampling
indicates that the mineralized zone is over one kilometre long. The zone
is not continuously exposed due to alluvial and thin volcanic cover.
However, HDG has located a small window within the volcanic cover 650
metres along strike from the trench which exposes weakly silicified and
iron stained carbonates returning values of 0.352 g/t gold, 5 g/t silver,
0.16% lead and 0.27% zinc, indicating that the mineralized system
continues under the volcanic cover.
A total of 187
samples have been collected from the HDG property position. Values range
from 0.05 to 100 g/t gold and from 0.08 to 492 g/t silver.
The Company
has also now acquired an additional land package at the San Antonio gold
property and holds four concessions which cover a total of 4,230 ha.
The San Antonio gold project represents an
exciting new acquisition for HDG with the potential to host large,
high-grade, and bulk-mineable gold systems in a region that has seen
limited modern exploration. HDG plans to quickly move the property forward
with continued geologic and geochemical investigations during the coming
months, to be followed by drilling.
