VANCOUVER, BRITISH COLUMBIA--(Marketwired - Apr 18, 2013) - Eagle Star Minerals Corp. (TSX VENTURE:EGE)(ELGSF)(E6R.F) ("Eagle Star" or "the Company") is pleased to announce significant progress with its 150 hole reverse circulation (RC) grid drill program at the PZE South Portion (Target D1). Drill results will be used in conjunction with that of an ongoing geophysical survey to construct a three dimensional outline of the mineralized zone. To date, the Company has finished 27 (RC) drill holes and in parallel, has completed over 80% of the 20 km geophysical survey planned for the area.
An important focus of the work program is to demonstrate the correlation between geophysical results and key geological units that will be used to increase the resolution of the mineralization outline between drill holes. The design of the drilling program will enable the Company to compare between results from this program and results from drilling densities used by other companies for resource delineation purposes on similar projects. Eagle Star chose a combination of three drilling grid densities of 50x50m, 100x50m and 200x200m to best support future resource estimation. Areas already identified to contain higher grade mineralization (>15% P2O5) will be targeted with 50x50m grid drilling. The total drilling area covers approximately 1400 by 500m.
The Company has developed and received Certified Reference Material (standards), which has already been inserted into the sample stream on the first batch of drill samples that were shipped earlier this week as part of their continuous effort to apply industry recognized QA/QC practices. Since laboratory phosphate standards are not commonly available commercially, the Company has developed low and high grade certified reference materials from mineralized ore at the project site. This is the ideal material for quality control reference standards since it is chemically and mineralogically identical to pit and drilling samples.
In addition, two trenches have been opened along lines with completed geophysics, drilling and pits. "These trenches are already providing important information for the interpretation of geophysical and grid drilling results. They provide a unique opportunity to test grade and geological continuity in areas with known geophysics and drilling. That is a key component in building a reliable three dimensional model of the mineralized zone. Initial mapping and geochemical field tests of the trenches have indicated a strong correlation between the geophysical interpretation and the geological mineralization controls. Moreover, since visual and qualitative geochemical field tests in all completed drill holes and trenches have indicated a higher grade mineralized interval, this zone appears to be laterally continuous over hundreds of meters, typically with a very low strip ratio," noted Mr. Fabio Mendonça, Eagle Star Minerals Exploration Manager.
Mr. John Harrop, PGeo, FGS, an independent Qualified Person with Coast Mountain Geological Ltd, has recently visited the site reviewing the project to determine that best sampling and QAQC practices are being followed during the drilling program. Following his visit, Mr. Harrop noted, "Considering the relatively short time Eagle Star has been involved in the Project, their team has effectively advanced the Project at a commendable rate." The Company has retained Coast Mountain Geological Ltd as the lead author of a Technical Report. Mr. Harrop has reviewed the technical content of this news release.
