After staking the current claim, Freeport-McMoRan Mineral Properties Canada Inc. engaged the services of C.J. Greig & Associates Ltd. to undertake a project wide soil, stream sediment, rock sampling, prospecting, geological mapping, and airborne magnetometer surveying program (Mitchell & Prowse, 2019).
In 2019, a total of 61 rock samples, 169 soil samples, and 17 stream sediment samples were collected in conjunction with geological mapping in areas of thick bush to locate mineralization, identify lithologies, and characterize alteration.
Geological mapping and prospecting focused on the Loljuh Stock and Pete Minfile occurrences. Both occurrences were re-located, sampled, and mapped in detail. A 1:10,000 map was completed that outlined the Loljuh stock and determined that the Telkwa Formation volcanic and sedimentary rocks it intrudes are dominantly gently westerly-dipping.
Stream sediment sampling showed the best gold and silver results appear to be sourced from the Loljuh Stock and Quartz-Sericite-Pyrite Knoll zones. Copper has a more wide-spread distribution, with anomalous values not only sourced from the Loljuh Stock and Quartz-Sericite-Pyrite Knoll zones, but also in the region southwest of the mapped Loljuh stock, perhaps sourced from a forest covered extension of the mineralized Loljuh stock. It should be kept in mind that the best multi-element results from the combination of soil, stream sediment, and rock sampling in this program may outline an east-northeast trend encompassing the Loljuh stock, and that most of the better gold results are found in rocks north of the stock. Molybdenum anomalies are generally restricted to creeks draining the Quartz-Sericite-Pyrite Knoll Zone and the southwest part of the Loljuh stock.
The 189-line kilometre Airbourne magnetic survey outlined northeast-trending linear magnetic low features that tend to mirror to some degree the anomalous soil geochemical trends on the Project. Magnetic highs appear to be associated with mapped Telkwa volcanic rocks and the unaltered Loljuh stock, whereas a relative magnetic low is present in an area of alteration and mineralization in the Loljuh stock.
In 2019, a helicopter-borne magnetic survey was flown across the Loljuh Project at 100 m line spacing with north-south tie lines at a 1 km spacing. Several distinct linear magnetic lows were identified and interpreted as regional to Project-scale faults. A prominent magnetic high roughly correlates with the mapped location of the Loljuh stock and more magnetic components of the Telkwa Formation, an area of magnetic destruction appears to correlate with the most strongly phyllic-altered and mineralized portion of the southwest mapped Loljuh stock. The larger anomalous Cu-in-soil area outlined in 2019 correlates closely with this main magnetic high in the survey with stronger anomalous samples tending to occur on the margins next to the high. The smaller anomalous copper area occurs on the flanks of a large linear magnetic low immediately downhill from a smaller magnetic high (Mitchell, 2019).
