VANCOUVER, BRITISH COLUMBIA– Evolving Gold (CSNX:EVG) (OTCB:EVOGF) is pleased to announce that it has completed its initial field mapping and survey program on targets the Company had previously identified as potential pegmatite hosts for lithium mineralization (see news release dated June 16th and July 5th 2016). A number of pegmatite bodies were identified, along with minerals associated with fertile granites, such as green muscovite and garnets that may be associated with lithium mineralized pegmatite. The geological work also identified a new type of target which is discussed below.
Geological mapping, conducted from July 9th to July 23rd, 2016, indicates that the area surrounding targets T5 and T8 is of particular interest for lithium prospectivity (for map, refer to Figure 1, below). During this initial exploration program, the field crew was able to find a series of minerals associated with fertile granite and possible mineralized pegmatite of lithium-cesium-tantalum (“LCT”) type, the potential host rocks for lithium mineralization. At T5, the team identified abundant green muscovite and accessory garnet, which are also observed in the Nemaska Lithium deposit, approximately 20 kilometres (“km”) to the southwest. Green muscovite and red garnet are typically found associated with fertile granite intrusions and within mineralized lithium host pegmatites (Bradley and McCauley, 2013).

The geological team also identified a large circular structure (approximately 1,000 metres (“m”) in diameter) associated with a topographic low and a geophysical magnetic high. (See Figure 2). This type of signature is sometimes associated with kimberlite or lamprophyre pipes, either of which are potential hosts for diamonds. This circular structure could also be associated with a carbonatite intrusion, which is sometimes associated with rare earth element mineralization. Other geological structures could also create a similar type of signature and further field exploration will be necessary in order to identify the source of this anomaly. The field work will include a till sampling program which, coupled with mapping of the outcrops and further geophysical interpretation, is expected to properly identify the feature.

Assay results of grab samples from pegmatite, paragneiss, granite and basalt units are currently pending. The field exploration team is compiling data in preparation for the second phase of ground work which will focus on the heart of the claims, located between targets T5 and T8, including further assessment of T1, which hosts the circular structure described above. This represents an area of 8 km by 2 km which current observations highlight as the most prospective for the presence of lithium mineralization. The remaining unvisited targets will also be part of the next field program, which is due to start on September 10, 2016. The historical geophysical data on the Property is also being compiled and will be reassessed along with our recent observations from the field by GDD Geosciences, to enhance the efficiency of field prospecting activities in the future.
Evolving Gold’s Chief Executive Officer, Mr. R. Bruce Duncan stated, “The reconnaissance field survey was successful in rapidly identifying a large area with a high potential for lithium bearing pegmatite discoveries. Our team has already identified pegmatite with mineral combinations similar to those observed at the Nemaska Lithium Project, to the southwest of our claim blocks.”
