Astral Drills 7.01 g/t Gold over 19 metres on Jumping Josephine Gold Project
|
| |
Vancouver, BC - Astral Mining Corporation (TSX-V AST) and Kootenay Gold Inc. (TSX-V KTN) are pleased to provide results for the second batch of samples, from eleven holes of the 20 hole Phase I drill program completed on the JJ Main Gold Zone, on the Jumping Josephine (JJ) Gold Project in southeast British Columbia. The JJ Main Zone remains open to the south, north and to depth (see attached long section map).
Results from HQ diamond drill holes #3 through to #13, include 19m averaging 7.01 g/t gold (62.32 feet at 0.205 opt*) from hole 07JD013, which includes 5m averaging 16.42 g/t gold (16.40 feet at 0.479 opt*). Based on current information the JJ Main Gold Zone has an estimated true width of up to 12.6m (41.32 feet). Mapping and geochemistry to date suggest that the JJ Main structure may extend for over three kilometres. See Table 1 for detailed results.
Visible gold was observed in 07JD012 and 013 and both are located on the southernmost fence drilled in the Phase I program (see attached long section map). The table below contains a summary of significant intercepts from ten holes recently reported by the assay laboratory. Assays are pending for the remaining 7 drill holes and will be released when received by the Company.
Furthermore, the company reports drill holes #1 and 2 (see June 14, 2007 news release) were submitted for re-assay. Drill hole #1 has now been upgraded by 27% to 10m averaging 12.65 g/t gold. See Table 2 below for detailed results.
Technical Summary
At the JJ Main Gold Zone 1,461m in 20 holes have been completed along 5 fences, testing the gold-bearing quartz stockwork zone over a strike length of 180m and to a vertical depth of 100m. Surface trenching on the stockwork zone during 2006 by Astral returned channel sample intervals of up to 31.19 g/t gold over 7m, including 133.91 g/t gold over 1m (see Astral's December 14th 2006 news release). The zone is characterized by silicified and sericitized quartz monzonite hosting a distinct zone of multi-phase stockwork veining and breccia zones controlled by a northeast striking structure. Early mapping and geochemistry suggest that this structure may extend for over three kilometres. Interpretation of aeromagnetic images show the structure to be underlain by a feature thought to be a buried intrusive stock approximately 2km in diameter. Astral suspects this stock may be genetically related to the stockwork-hosted gold mineralization and is applying a porphyry target model to the project. A significantly expanded Phase II diamond drill program is being planned to test the stockwork zone along strike and at depth and to test for a potential underlying buried porphyry deposit.

Based on the results received to date, gold grades and interval widths generally increase towards the south as evidenced by hole 07JD013. To the north drill holes 07JD008 and 009 were collared in quartz stockwork, and lower grades in these holes may reflect an incomplete sample across the mineralized zone.
As stated previously (see June 14, 2007 news release), reject material from the first batch of samples reported on from the Phase I drilling program was submitted to a second laboratory, ALS Chemex in North Vancouver for metallic gold check assays. This work returned a general increase in gold values up to 40.8% (07JD002 between 10-12m). The original interval from 07JD001 of 10m averaging 9.95g/t gold has now been upgraded by 27.1% to 10m averaging 12.65g/t gold. The ALS samples utilized a 1kg sample size, 100% larger than the sample size from the original 500g metallic gold analysis completed by Acme.

With the recent completion of 643.3m in 2 holes at the Bonanza Pass target and 544.2m in 9 holes at the Albion-Dubrovnik targets in the southern part of the JJ property, the Phase I drilling program at on the JJ Projected has been completed. Surface trenching over several new prospects on the JJ Project is now underway and an expanded program of soil sampling and geological mapping will commence by the beginning of August. Ministry of Energy, Mines and Petroleum Resources permitting for the Phase II expanded drill program is complete and is planned to commence later in the summer once all results from the current phase of drilling have been received and compiled. Astral has a diamond drill rig booked for this work. To view all of the results from Astral's 2006 summer work programs visit www.astralmining.com.
All drill core samples comprised 1m intervals of HQ drill core halved by diamond core saw. All analytical results reported herein are from 500g samples analyzed using the Metallic Gold method or by 30gm Fire Assay (07JD003) by Acme Laboratories in Vancouver B.C. or 1kg samples analyzed by Metallic Gold method at ALS Chemex in North Vancouver B.C. Observation of gold concentrations in the coarse versus fine fractions from the original analyses prompted Astral to forward mineralized intercepts to ALS Chemex for confirmatory metallic screen analysis using the larger, 1kg sample size.
All analytical work reported herein was carried out by Acme Analytical Laboratories Ltd, Vancouver, or ALS Chemex, North Vancouver, both internationally-recognized analytical service providers. In addition to laboratory standards Astral has included independently-prepared standards into the sample sequence to assure proper quality assurance/quality control (QA/QC). Exploration work reported in this release was completed under the supervision of Astral's Project Geologist Dale Brittliffe, B.Sc.. Technical information contained in this release has been reviewed by Dr. David A. Terry, P.Geo., Director and Vice President of Exploration for Astral Mining Corporation, and a Qualified Person as defined in National Instrument 43-101.
Astral is earning a 60% interest in the JJ Project from Kootenay (see April 12, 2006 news release).
