The Lin 18 occurrence is situated at the southern end of the Swannell Ranges (Omineca Mountains), approximately 43 kilometres east-northeast of Takla Landing.

The area is underlain by monzonite, granite and alaskite assigned to the Late Triassic to Early Cretaceous Hogem Intrusive Complex, which have been emplaced into volcanic rocks of the Middle Triassic to Lower Jurassic Takla Group east of the Pinchi fault zone. The plutonic rocks form an elongate batholith, extending from Chuchi Lake, and north to the Mesilinka River.

Chalcopyrite and molybdenum mineralization reportedly occur in minor fractures cutting monzonite (Assessment Report 3997, Plate I, page 4). Although rock samples do not appear to have been taken, geochemical values from soil samples around the area were anomalous in copper and molybdenum.

In 2011, Kiska Metals outlined a small molybdenum, zinc, lead, and arsenic-soil anomaly on the north side of Kwanika Creek, about 900 metres southwest of the plotted location of the Lin 18 MINFILE occurrence. This anomaly was dubbed the Lin anomaly by Kiska and consisted of a seven sample soil anomaly along a line of samples taken beside a new forestry road.

Work History

The Lin group of some 90 claims was owned in 1972 by W.B. Bacon and the Luc Syndicate carried out a geochemical soil survey in the area consisting of approximately 700 samples.

In 1974, Anglo-Bomarc Mines Ltd. completed a 10 line-kilometre magnetometer survey and a geochemical (soil and silt) survey (351 samples) over 18.5 line-kilometres on the area as the Smoke claims.

In 1985, Imperial Metals Corp. completed Imperial Metals Corp. completed a program of soil sampling on the area immediately south of the Lin 18 occurrence as the Kwandyke 1-2 claims. This work identified an anomalous zone of lead–barite-in-soil, located approximately 4.6 kilometres to the south of the Lin 18 occurrence, extending for at least 300 by 300 metres and open to the west.

In 1990 and 1991, Golden Rule Resources Ltd. completed programs of geological mapping, geochemical (rock, silt and soil) sampling and a 1500 line-kilometre airborne geophysical survey on the area as the Takla property. Also in 1991, Pacific Rim Mining Corp. completed a program of silt and soil sampling on the area immediately north as the Kwan 5-8 claims.

During 2005 through 2010, Redton Resources and Geoinformatics Exploration Canada Inc. undertook work on the regionally extensive Redton property, which covered the Falcon (MINFILE 093N 068) occurrence to the south (just north of Nation Lake) and north to the Tak (MINFILE 093N 067) occurrence, approximately 6 kilometres south of the Omineca River. In 2005, a 5764.0 line-kilometre airborne magnetic and electromagnetic survey was completed on the area as the Takla-Redton property. In 2006, a program of geological mapping and geochemical (rock, silt, and soil) sampling was completed on the property along with 12 diamond drill holes, totalling 4032.5 metres, on the Takla-Rainbow (MINFILE 093N 082) and Tak occurrences. In 2007 and 2008, programs of geochemical sampling (rock, silt, and soil) sampling, ground geophysical surveys and 10 diamond drill holes, totalling 3784.0 metres, were completed on the property. This work centred primarily on the Takla-Rainbow occurrence to the north and Falcon occurrence to the south. In 2010, a subsequent AeroTEM survey by Redton Resources identified 65 electromagnetic anomalies on the property.

In 2011, Kiska Metals Corp ran a soil sample line over the Smoke Uranium showing (093N 175), the Smoke Copper showing (093N 152) and the Lin 18 showing (093N 168) areas. A few sporadic anomalous gold in soils were obtained but no significant or consistent elevated copper, molybdenum, lead, or zinc values were obtained in the Smoke Urnaium or Smoke Copper areas though one anomalous area was found southwest of the plotted Lin 18 showing (Figure 12, Assessment Report 32504).

During 2012 through 2014, Kiska Metals Corp. completed further programs of geochemical (rock, silt, and soil) sampling, geological mapping, and ground geophysical surveys on the Redton property.

Also in 2014, Serengeti Resources Inc. completed a program of geochemical (soil, silt and rock) sampling and a 7.8 line-kilometre induced polarization survey on the area as the Kwanika East-Smoke property. The following year a 328.0 line-kilometre airborne magnetic survey was completed.

In 2016, Serengeti Resources Inc. completed a 12.0 line-kilometre ground induced polarization survey on the area. This work identified a zone of moderate to high chargeability response on the two-line survey over the strongest magnetic feature in the west, whereas elevated chargeability values were recorded at depth on the two most eastern traverses.
