Aur Resources Inc. Intersects Significant Copper Mineralization on La Verde Property in Mexico.

TORONTO -- Aur Resources Inc. (TSX:AUR) has intersected significant copper mineralization and made an important new copper discovery on its La Verde copper property located in west-central Mexico approximately 300 kilometres west of Mexico City.

Drilling to date has tested two areas of the property on which previous owners had outlined near surface resources of 72.6 million tonnes at an average grade of 0.7% copper (see note 1) and has also intersected new mineralization, in a previously untested area of the property, associated with a large geophysical anomaly. The La Verde property has the potential to host a large copper deposit and the ongoing 2005 drilling program has now been doubled to 15,000 metres, in 40 holes, at a cost of $2.3 million, in order to accelerate the evaluation of this new discovery.

In late 2004, a drill program designed to evaluate two shallow mineralized breccia zones was initiated and, to date, 9 holes have been completed (Holes 1-8 and 10) which have confirmed the presence of significant copper mineralization above a depth of 200 metres (see Figure 1, Table 1). The best intersections obtained in this drilling were:

East Zone
----------
Hole #6 179.4 metres grading 1.02% Cu
Hole #3 115.1 metres grading 1.15% Cu
Hole #4 115.5 metres grading 0.72% Cu
Hole #8 78.5 metres grading 0.77% Cu

West Zone
----------
Hole #1 21.9 metres grading 1.11% Cu
Hole #2 23.5 metres grading 2.85% Cu.

These drill results confirm the presence of near surface significant copper mineralization in the zones where previous workers had outlined the 72.5 million tonnes of resources.

In conjunction with this shallow drilling, an IP geophysical survey was carried out in an effort to detect additional mineralized areas on the property. This survey outlined an IP anomaly approximately 4.0 kilometres in length and from 750 - 1500 metres wide surrounding the area of known mineralization. The IP anomaly is continuous and is located at a greater depth than all previous drilling carried out on the property. Copper mineralization is known to occur at surface over much of the IP anomaly outline (see Figure 1).

Hole # 9 was drilled to begin the evaluation of the IP anomaly. Copper mineralization, grading an average of 0.49% Cu over a core length of 427.1 metres, was intersected in this hole, together with significant gold and silver (Table 1). Hole # 9 was stopped in mineralization at 681 metres due to equipment limitations. The copper mineralization was principally chalcopyrite and bornite hosted in a brecciated, multiphase intrusive complex. The extent of this newly discovered copper mineralization is unknown at this time, however, based upon the size of the IP anomaly and the extent of the copper mineralization known on the property at this time the potential exists for a large tonnage copper deposit on the La Verde property. The presence of gold, silver, molybdenum and cobalt mineralization in several holes is also considered encouraging.

In an effort to accelerate the evaluation of this new copper discovery and its relationship to the known shallow, high-grade copper zones, the 2005 drilling program has been expanded to 40 diamond drill holes totalling 15,000 metres. This drilling will focus initially on the area within 400 metres of Hole # 9 and at depth below the known East Zone mineralization. Drilling to evaluate the IP anomaly, both to the east and west of the areas of known mineralization, will also be carried out in 2005. This program is in progress and the next results are expected to be available by the end of July 2005.

The La Verde property covers an area of 104 square kilometers. Aur has the right to earn a 100% interest in this property by making cash payments totalling $6.8 million, of which $0.8 million is payable by October 2008, and by paying a 0.5% net smelter return royalty to the vendor.

The La Verde copper project is one of the four copper projects and one gold project scheduled to be drilled in 2005 as part of Aur's $50 million expanded commitment to business development over the next five years.

Notes to Table 1

All holes were drilled at minus 55 degrees with the exception of holes 5 and 6, which were vertical. Collar elevations are metres above sea level.

In addition to Cu, Au and Ag hole 3 intersected 115.1 metres grading 0.018% Mo and 0.066 % Co, hole 4 intersected 115.5 metres grading 0.019% Mo and hole 7 intersected 32.8 metres grading 0.057% Mo.

HQ and NQ-size core samples are cut with a saw at the project site with half of the sample kept as a permanent record and half of the sample sent to SGS Mineral Services preparation laboratory in Durango, Mexico where a 250 gram pulp sample is prepared. The pulp samples are then couriered to SGS's laboratory in Mississauga, Ontario for analyses. Gold analysis is by 30 gram fire assay with an atomic absorption finish. In addition, all samples are subjected to multi-acid acid digestion followed by 31 element ICP-OES analyses. Samples with over-limit Cu, Ag, Mo and Co are reanalyzed for these elements by subjecting the samples to multi-acid digestion followed by ICP-MS analysis. QA/QC, including standard samples inserted every 10 samples, lab standards and duplicates, as well as chain of custody  is monitored by Aur. Mr. Don Dudek, P. Geo., Aur's Exploration Manager, is the qualified person as defined by NI 43-101 for the project, and has verified the information contained in this release.

Note 1; The mineral resource was included in the 1972 feasibility study completed by Compania Ralph M. Parsons de Mexico S.A. on behalf of Lytton Minerals Ltd. and was calculated prior to the enactment of NI 43-101.
