According to the company:
With regards to the Preston project and as summarized in the Preston 43-101 report, more than $4.7 million in exploration has been conducted over the past two and a half years resulting in fifteen high-priority drill target areas located within eight prospective exploration corridors.
Exploration in 2013 consisted of airborne EM-Magnetic, radiometric surveys and prospecting around targets identified in historic reports. The VTEM survey completed in August 2013 mapped over 300 kilometres of graphitic-type conductor segments, some approaching 10 kilometres in length within the eastern claims of the Preston project. Additional ground follow-up of the newly identified airborne conductor corridors and radiometric anomalies was carried out by systematic lake-bottom sediment sampling and water radon sampling surveys, which in turn was followed by soil, biogeochemical and radon-in-soil sampling surveys. In 2014, ground gravity and horizontal loop electromagnetic (HLEM) surveys were followed up by RadonEx radon-in-water and radon-in-soil sampling surveys, which was followed up by a diamond drilling program consisting of nine holes in 4 target areas totaling 1,571 metres. Work in 2015 included a gravity and horizontal loop electromagnetic survey (HLEM) in conjunction with a RadonEx radon-in-water and radon-soil sampling survey, and followed up by 1,318 metres of diamond drilling in five holes.
