Vancouver, British Columbia: Evolving Gold Corp. is pleased to announce it has completed the planning for an exploration program on its 100%-owned Toro Project that will assess the potential of the 24 kimberlite targets previously announced by the Company (see news release dated September 15th, 2016). The Toro field campaign, being conducted by two geologists and two technicians, began on October 12th, 2016. The Company is simultaneously completing Phase 2 of its field exploration activities on the Lithium Lakes Property, initially announced September 8th, 2016, which are being conducted by an additional two geologists and two technicians.
Toro Property Field Program
In this first phase of field exploration of the kimberlite targets, approximately half of the circular magnetic anomalies identified on the Toro Property have been selected for geological mapping, field prospecting, and till sampling for kimberlite indicator minerals (“KIM”) glacially down-ice from the targets.
Two two-man geological assessment teams are being transported in the field by helicopters supplied by Canadian Helicopters. One team is conducting geological mapping directly on the selected phase one anomalies and is also inspecting down-ice for glacial erratics that could have derived from near-by kimberlite intrusions, work which may provide quick verification of the presence of kimberlite. This same team will then conduct a helicopter borne inspection of the other kimberlite targets that are not part of the detailed mapping and till sampling in phase one of the program.
The second team is performing a till sampling survey down-ice from the circular magnetic anomalies selected for phase one assessment work. Till sampling will occur along 3 survey lines, covering the area between the anomaly and 1.5 kilometres down-ice, across the width of the anomaly. The crew is expected to collect between 20 and 25 till samples per anomaly. The coarse till samples will be screened with a 20 mesh sieve, and 10 kilograms of the finer material will be tagged, bagged and sealed on site. The samples will be transported back to the camp by helicopter and shipped to southern Quebec by truck. The samples will then be shipped to C. F. Mineral Research Ltd. (Kelowna, BC), to determine the presence of KIM by means of heavy mineral concentration, optical picking, mounting of grains for microscopic analysis, and the determination of their micro-chemistry using electron microprobe analysis (“EMPA”). The assessment process is estimated to take a minimum of 2 months.
Glacial till sampling for KIM is an effective technique for identifying potentially diamondiferous kimberlites for three reasons: 1) KIM form under the same high-temperature and high-pressure conditions in the upper mantle which favour the formation and stabilization of diamonds; 2) KIM are resistant to weathering and other erosive events at the Earth’s surface; and, 3) KIM are much more commonly found in kimberlite intrusives than are the target diamonds themselves. The KIM suite of minerals include: Hurzburgitic Cr-pyrope garnets, Eclogitic pyrope-almondine garnets, Cr-diopside, Cr-spinel, chromite, magnesian ilmenite, and magnesian olivine (McCLenaghan, 2007; Nowicki, 2007). All of the KIM have densities above 3 grams per cubic centimetre, and can be concentrated from till samples by means of dense media separation. The dispersal pattern, concentration (number count per sample), and micro-chemistry (by EMPA) of the KIM in till samples can greatly assist in determining the probability that a specific target might be a diamondiferous kimberlite.
Evolving Gold’s Chief Executive Officer, Mr. R. Bruce Duncan stated, “Management is very excited to so quickly be able to start work on the field assessment of the anomalies defined by an airborne survey. The Company intends to first determine whether the magnetic anomalies are of interest for diamond exploration, but the potential for other types of mineralization in these same targets has not yet been ruled out at this stage of exploration.”
Lithium Lakes Property Field Program
A team of two geologists and two technicians has begun Phase 2 fieldwork at Lithium Lakes, performing geological mapping and prospecting in the area that was previously defined by the Company as having the most potential for lithium mineralization (see news release dated September 8th, 2016). This area surrounds Targets T5, T1 and T8, where minerals found during the first reconnaissance survey indicate the possible presence of fertile granites that may be associated with lithium mineralized pegmatite. Special attention will be given to the mineralogy in order to determine the presence of mineral indicators for fertile granite or lithium pegmatite. Boulder-field prospecting will also be done down-ice from the individual targets. This phase of exploration will also include field prospecting on Targets T3, T4, T9 and T12, which were not part of the earlier field work program. The Company has not yet received assay reports from samples collected during previous field work at Lithium Lakes.
