Astral Commences Drilling on Gold Springs Property, Nevada

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 31, 2006) - Astral Mining Corporation (TSX VENTURE:AST)(Frankfurt Stock Exchange: WKN # A0JDX3) is pleased to announce it has commenced a 3,000m (9,300ft.) reverse circulation drill program on its Gold Springs epithermal gold property, which straddles the Utah/Nevada border, and has the potential to host both high-grade vein and bulk tonnage precious metal deposits. The drilling will test three geological-geophysical target areas with the majority of the program focussed on the Jumbo zone where past drilling has intercepted 2.34 g/t gold over 24.4m and 17 g/t gold over 3.0m(1). The Jumbo vein can be mapped on surface for 760m and ranges in width up to 7.5m locally splitting into a 20m wide "vein zone", hence the name "Jumbo". The Jumbo vein is enveloped by a stockwork/alteration zone up to 100m wide.

The Gold Springs project area has a long history of gold exploration and production. Precious metal mineralization was first discovered in the area in 1896. The current drill program will test for extensions at depth and along strike to gold-bearing vein systems which are exposed at surface and have had only limited shallow drill-testing by previous operators. The drilling will also target large geophysical resistivity anomalies situated at moderate depth below or along strike from known gold-bearing vein systems at the Jumbo, Jennie North and Etna zones.

In 2004 Astral Mining Corporation optioned the property and commenced an exploration program comprising detailed surface rock sampling, geological mapping, ground magnetics and Controlled Source Audio Magneto Tellurics (CSAMT) surveys. Astral has collected 87 rock chip samples from the property. Results ranged in value between 8 ppb and 9.4 g/t gold; 19 samples assayed greater than 1 g/t gold. Silver assays ranged from less than detection to 93.25 g/t silver.

In addition to the Gold Springs property in Nevada Astral holds a 100% interest in the Scraper Springs and Emmy properties along the northern extension of the Carlin Trend and the REF gold property at the southern end of the Battle Mountain-Eureka Trend. In British Columbia, Canada the Company holds an option to earn a 60% interest in the JJ intrusive-hosted gold property. Detailed descriptions of the Company's properties can be found on its website at www.astralmining.com.

Technical Summary:

Astral is earning a 100% interest in the Gold Springs property, subject to a 3% NSR - 1.5% of which can be purchased for $1.5M, by making cash and share payments and completing work commitments. The property comprises 127 claims and covers an area approximately three kilometres in an east-west direction by six kilometres in a north-south direction. The property is located within the Stateline Mining District along the Nevada-Utah border which had small-scale production from at least 13 high-grade narrow veins from the late 1800s through to the mid 1900s. Gold Springs is underlain by Tertiary-aged intermediate to felsic volcanic rocks that have demonstrated potential to host both precious metal deposits in high-grade narrow vein zones and quartz stockwork/disseminated bulk tonnage targets.

The current drill program will comprise a minimum of 3,000m of reverse circulation drilling in 10 holes and will test three geological-geophysical targets including:

Jumbo:

The Jumbo zone is dominated by a prominent steeply east-dipping north-striking vein which is up to 7.5 metres wide, and in places splits into a double vein zone up to 20m wide, and can be traced on surface for 760 metres. The vein is primarily white and massive quartz with crystalline, crustiform, colloform, sucrosic, comb, and quartz pseudomorphs of calcite textures. Less abundant adularia and carbonate material are also present; numerous clasts of the volcanic host occur in the vein.

In 1988 Energex drilled 8 holes totalling 701m along 250m strike of the southern Jumbo vein. Highlights included: 2.34 g/t gold over 24.4m and 17 g/t gold over 3.0m(1). These results have not been followed up on and mineralization is open to depth and along strike. Twenty-three samples were collected from the Jumbo vein during August and September 2004 by Astral ranging up to 3.1 g/t gold with 17 samples containing greater than 100 ppb gold. The CSAMT survey detected a resistive zone associated with the Jumbo vein system measuring approximately 1500m north-south and up to 500m wide. The width of the resistive area suggests that there are multiple north-south striking structures in the Jumbo area. To the south the zone narrows and is offset by a right lateral fault. At depth the resistive rock cuts the layered andesites and connects to a larger resistive body at approximately 300m depth interpreted as a possible zone of silicification related to the overlying epithermal system. The current drill program will test with a minimum of 7 holes for extensions at depth and along strike to the gold zones identified by Energex and will also test the deep CSAMT anomaly.

Jennie North:

The Jennie Mine was one of the more significant historical producers in the Stateline district and lies just south of the central Gold Springs property boundary. The vein system that was exploited by the Jennie Mine was reportedly cut off to the north by an east-west oriented fault(2). The CSAMT survey carried out over the Gold Springs property indicates that a large area of resistive rocks occurs at depth below the hill capped by rhyolite ash-flow tuff that is located to the north-northeast of the Jennie Mine. The Jennie Mine area shows up in the CSAMT data as a small nose of resistive rock that is connected to this larger body. The Jennie North resistive zone is 800 metres north-south, up to 500 metres wide and occurs at approximately 150m depth. The zone of resistive rock under the hill is unexplored, but it has been speculated that the northern extension of the Jennie vein occurs under this hill as far back as 1928(2). Two holes are planned to test the Jennie North target.

Etna:

The Etna Zone is covered by a separate group of 12 claims in the south-eastern portion of the Gold Springs Project area. Mineralization at Etna occurs primarily as quartz stockwork in brecciated andesite which dips 60 degrees to the west and forms a broad prominent north-south ridge 1200 metres long. The Etna zone varies from 30-75 metres in width with the larger widths towards the north. Individual quartz veins are normally less than 0.6 metres. Silicification associated with breccia and stockwork zones grades into variably-argillized andesite to the west.

Previous drilling on Etna was carried out by Energex in 1988 (2 holes) and North American Gold in 2003 (3 holes). Highlights of the Energex drilling include 38.0 metres grading 0.3 g/t Au and 8.8 g/t Au over 3.0 metres(1). Thirty-eight rock chip samples were collected from the Etna zone during mapping in August and September 2004; 25 samples contained greater than 100 ppb gold, and the highest sample contained 9.4 g/t gold. The CSAMT data shows that high resistivities correspond to the mapped stockwork zone, abruptly ending to the south. Cross-sections of the CSAMT data through the Etna zone shows that the resistive rocks cut-through the layered andesites and are connected to a larger resistive body that is in the range of 300-365m deep. One hole is planned in the current program as a deep test of the Etna zone.
