Astral Drills 5m Averaging 39 g/t Gold and 93 g/t Silver at Los Crestones Project, Sierra Madre Gold-Silver Belt, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 12, 2011) -

Editors note: There is a photo associated with this press release.

Astral Mining Corporation (TSX VENTURE:AA)(TSX VENTURE:AA.WT)(PINKSHEETS:AAMJF)(FRANKFURT:A7DA) ("Astral" or "the Company") is pleased to report the second batch of results from drilling at the Los Crestones property, Sinaloa state, Mexico. Highlights from holes 7 to 12 of the recently-completed 18 hole 2,618.61m program include 5m averaging 39.1 g/t gold, 93.3 g/t silver and 2.13% copper. This interval from hole 11LD011 included 1m of 162.5 g/t gold, 270 g/t silver and 3.02% copper. Intervals stated are core length. True widths are not known as mineralization geometry is not completely understood at this time.

Holes 10, 11 and 12 on the Bohemia vein tested a high priority zone previously sampled on surface by Astral. Current interpretation of this section indicates up to three sub-vertical mineralized vein/breccia bodies exist within an envelope of approximately 25m. The mineralization remains open at depth and requires additional drill testing to confirm geometry and continuity.

Seventeen of eighteen holes were completed to programmed depth. Hole 11LD013 was abandoned due to poor ground conditions. Drilling targeted low-medium sulphidation epithermal style mineralization in three sub-parallel vein/breccia zones "Corona", "Bohemia" and "Indio". The zones trend north-south and have been mapped on surface for up to 930m (for drill plan see Astral's current map page at the following link: http://www.astralmining.com/los-crestones/losmaps). The mineralized zones consist of silicified breccias and quartz stockwork veins which exploit brittle fractures within multi-phase felsic intrusives and minor intermediate volcanics.

Table Notes
  1. Intervals are reported as core length. Astral cannot accurately estimate true width as the vein geometry is not clearly understood at this time.
  2. No top cut has been applied.
  3. Gold equivalent assumes 100% metallurgical recovery, Au at $1500/oz, Ag at $30/oz, Cu at $3/lb, 1 troy oz = 31.10348g, 1lb = 453.593g
  4. Drilling included HQ and NQ2 sized drill core sampled at one metre intervals where lithological contacts reasonably allowed.
  5. Samples were halved using diamond core saw. Half-core is stored on site while the other half was sent to the laboratory.
  6. Samples were sent to ALS Chemex in Hermosillo, Sonora for standard preparation and shipped to the Vancouver laboratory for analysis.
  7. Samples were analysed for a standard multi-element suite by aqua regia digestion with ICP-AES finish on a 0.5g sample charge (ALS code ME-ICP41). Overlimit analyses for silver, copper, lead and zinc were re-run using an Ore Grade aqua regia digestion with ICP-AES finish on an a 0.4g sample (ALS code MEOG-46).
  8. Samples were analysed for gold by routine fire assay and AAS finish on a 30g nominal sample weight (ALS code Au-AA23). Samples returning over 10 g/t gold were re-assayed by fire assay fusion, gravimetric finish on a 30g charge (ALS code Au-GRA21).
  9. Astral incorporates blanks, certified standards and duplicate assays as part of industry standard QA/QC checks.

Astral is awaiting results from the remaining five holes in this round of drilling. Due to high gold and silver values returned from the latest results, confirmation analyses including metallic screens for gold will be conducted on stored coarse reject material.

Manfred Kurschner, CEO and President comments, "The results from this first drilling program are extremely encouraging and have far exceeded our expectations. Furthermore, Astral's limited sampling programs along strike and adjacent to the discovery area have yielded a number of high priority exploration targets to focus on in 2012."
