Delta Mining and Exploration Releases Second Phase Exploration Report - Diamond Indicator Minerals Identified; Bulk Sampling for Macro-Diamonds Recommended

NEW YORK, Feb. 12 /PRNewswire-FirstCall/ -- Delta Mining & Exploration (OTC: DMXC) is pleased to announce the results of the second phase of exploration work undertaken by Apex Geoscience Limited ("Apex") on Delta's Grassrange District Properties in Montana. The Apex team carried out detailed mapping and collection of a total of 14 samples for diamond indicator mineral analysis. Samples were processed at the Saskatchewan Research Council laboratory, Canada, and analyzed by R.L. Barnett Geological Limited, Lambeth, Ontario, Canada. The presence of diamond indicator minerals which plot within the diamond stability field is indicative of an environment that is permissive for the preservation of diamonds.

Work focused on the Homestead and Three Buttes kimberlite bodies but samples were also collected from the Teigen Butte, Rattlesnake Butte, TV Hill, Half Moon and Road Dyke targets. In total 1,593 grains were picked as possible diamond indicator minerals (DIMs) of which 96% were deemed to be kimberlitic (1533 grains were kimberlitic and 60 were determined to be non- kimberlitic). The results show that the Homestead body ranks as the highest priority target. Samples from Homestead contain a number of sub-calcic garnet grains (G10s) and clinopyroxenes that plot within the diamond stability field and overlap with that of diamond inclusions. Chromite minerals collected from Homestead and Three Buttes mainly plot outside of the diamond inclusion field, but trend into the field.

On the other properties such as the Rattlesnake Butte, material was determined to contain a number of what are viewed as "high interest" chromites, whilst at Teigen Butte eclogitic garnets were recovered, which are also considered quite significant.

Pyrope garnet, clinopyroxenes and chromite minerals are among the most typical diamond indicator minerals found in kimberlites. The flaws in diamond, also known as inclusions, frequently include minerals such as pyrope garnet, chromite and diopside and other minerals. 'Diamond inclusion field' refers to mineral compositions similar to that of minerals found as inclusions in diamond. The mineral chemistry of specific mineral grains provides important information about the composition of the mantle in a specific area and its likelihood to have preserved diamonds.

Following analysis of the diamond indicator mineral study, which can be viewed in its entirety at www.deltamine.com and www.fortuneir.com, Delta's management, is very encouraged by the results. In addition, Apex has recommended a program of sampling for macro-diamonds utilizing large samples (up to 10 tonnes) on the Homestead, Three Buttes, Teigen Butte and Rattlesnake Butte targets. Delta and Apex are now planning the implementation and timing of this follow-up program.

Delta's Chief Executive Officer, Mr. Brett Rodli cited with enthusiasm that "the recent results provide the impetus to complete further exploration and seek out potential joint venture partners."
