Geodex Minerals Ltd.: South Dungarvon Drill Program Intersects Tin Mineralization

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug 1, 2013) - Geodex Minerals Ltd. (TSX VENTURE:GXM)(FRANKFURT:G2W) (the "Company" or "Geodex") announces that it has received the drilling results for its South Dungarvon Tin Project in central New Brunswick. Three holes were completed for a total of 276 metres for which all analytical results have been received.

The South Dungarvon property hosts multiple tin mineral occurrences within and along the contact of the Late Devonian Dungarvon Granite. The focus of the South Dungarvon 2013 work was to complete a first stage drill program to test an area in the eastern region of the property where previous operators had identified tin bearing boulders and tin soil anomalies. Geodex confirmed and partially defined these soil anomalies in 2012 in an area covered by a blanket of glacial till, largely masking the underlying bedrock. The tin anomalies in the area of the 2013 drill program are associated with an interpreted major northeast trending regional structure.

Drill holes SD-13-01 and SD-13-03, drilled to create a scissor pattern on the same north-south section, both intersected near-surface tin mineralization. This establishes a new tin occurrence in the eastern region of the property. The tin mineralization intersected in these holes was mainly in quartz (+/- chlorite, fluorite, carbonate) veins cutting the Late Devonian Dungarvon Granite and as local disseminations and clusters in the granite. SD-13-01 was drilled to the north at a 45 degree dip to a length of 85 metres. SD-13-03 was collared 25 metres further north, and drilled to the south at a 55 degree dip to a length of 76 metres. Both holes were within an area of tin soil anomalies and the approximate area of the reported structure. There is approximately 5 metres of glacial till in the immediate area of these drill holes. Veining was locally frequent in both holes, which Geodex believes is a result of the mapped structure in this area and a key controlling feature of the mineralization.

The results included:

Drill hole SD-13-02 was collared approximately 500 metres northwest of SD-13-03. SD-13-02, which tested the northern part of the soil anomaly, failed to intersect significant mineralization and appears to have been collared north of the target structure.

David Martin, VP New Brunswick Operations, commented, "The small 2013 drill program established a new area of tin mineralization in the eastern region of the South Dungarvon Project. A first stage drill program in a glacially till covered area has a number of purposes. We are pleased that our drilling successfully intersected tin mineralization and the structure that is associated with the mineralization as well as providing some valuable data on the property geology. The tin soil anomalies and reported fault continue east and west of SD-13-01 and SD-13-03, providing targets for further drilling."

Geodex also reports that it has terminated its agreement on the Dungarvon Tungsten-Molybdenum-Tin Project on which it reported drill results earlier. Geodex retains 100% ownership of the South Dungarvon Project.

Geodex's disclosure of a technical or scientific nature in this press release has been reviewed and approved by David Martin, P. Geol., Geodex's Vice President New Brunswick Operations, who acts as the qualified person under the definition of National Instrument 43-101.
