Aurogin Resources Ltd.: El Sastre Resource Estimate

TORONTO, ONTARIO--(CCNMatthews - March 29, 2005) - Aurogin Resources
Ltd. ("Aurogin")(TSX VENTURE:AUQ) is pleased to announce that an
estimate of the El Sastre mineral resource has been completed. The
"Indicated Resource", using a 1.0 g/t Au cut off, totals 370,000 tonnes
grading 4.1 g/t Au containing 49,251 ounces of gold. The "Inferred
Resource", also using a 1 g/t cut-off, totals 1,165,000 tonnes grading
3.1 g/t Au containing 117,265 ounces of gold. The resource was estimated
by Toren K. Olson, P. Geo., the Independent Qualified Person responsible
for the 43-101 Technical Report dated March 23, 2005 which will be filed
shortly on SEDAR. The mineralization at El Sastre has been traced over
an area of at least 500m by 300m. The resource estimate was based on
assays from 38 percussion drill holes, 8 reverse circulation drill holes
and over 1000 trench, pit, channel and chip samples. A block model was
developed using a search envelope of 10x10x5 meters for Indicated
Resources and 25x25x5 for Inferred Resources. A specific gravity of 2.5
was used and no assays were cut. Investors should note that mineral
resources which are not mineral reserves do not have demonstrated
economic viability.

"We are very pleased with the results of the resource estimation" said
John H. Paterson, P.Eng., Aurogin President and CEO. "Having grades in
the 3 to 4 gram per tonne range to go along with the excellent leaching
characteristics of the material make this deposit a very attractive heap
leach development candidate" he added.

Column, bottle roll and percolation testing was carried out on a bulk
sample taken from the property in July 2004 and all gold recoveries were
greater than 92%. The column test was run on un-agglomerated, minus 2
inch material and gave a recovery of 97% in 15 days (News Release 2004-9
October 18, 2004).

Aurogin is actively exploring in Canada and Guatemala. Further
