EM Group Update

Having now received the XRF soil results from ALS Geochemistry's laboratory in Reno and the ICP-AES grab samples from Bureau Veritas Inspectorate's laboratory in Reno, Great Western Mining (AIM: GWMO; Euronext Growth: 8GW) now provides the following update on the EM Group ("M8") fieldwork conducted in June 2019.

Analysis of the soil samples has identified two strong trends of copper anomalism, centred along the two fault corridors previously recognised during the geological mapping exercise, Figure 1. http://www.rns-pdf.londonstockexchange.com/rns/7576H_1-2019-8-2.pdf The copper anomalies are most pronounced atop pre-tertiary basement lithologies (slates and siltstones), which are postulated to be horst blocks, within a NE-SW basin and range type setting. 

Grab samples were also taken during the mapping phase with encouraging results, including 0.39% Cu, Table 1, in the vicinity of the northern fault corridor, along with anomalous molybdenum and zinc readings.  Zinc appears to ring the copper anomalies and was seen in both the grab samples and the soil samples, suggesting a metal zonation around the target area. Elevated molybdenum, a common associated metal in porphyry copper systems, is coincident with elevated copper in the northern half of the lower fault block.

Table 1 Results for copper, molybdenum, and zinc, from the 34 grab samples conducted at EM Group, June 2019. Anomalous results >0.1% (>1000ppm) shown in bold.

GWM is encouraged by the results of both the initial soil sampling programme and the grab sampling programme. The next phase of exploration work at M8 will be an infill soil programme centred on and around the two fault blocks, which will better define the trends seen in the current broad spaced pattern.  Following this programme, an Induced Polarisation and Resistivity survey ("IP survey") will be conducted on top of and along strike of the main copper trends, the objective being to identify sulphide targets which may be blind to surface mapping and geochemical sampling techniques.

Chief Executive David Fraser commented: "The results of the soil and grab sample programme at M8 confirm GWM's initial assessment suggesting a potential buried copper porphyry. The Company will now quickly move forward with a more targeted soil programme and IP survey to identify targets for drilling. As always we will keep shareholders updated as work continues."
