The Fal occurrence is situated just south of the Swannell Ranges (Omineca Mountains) near the shores of Tchentlo Lake, approximately 65 kilometres southeast of Takla Landing. The area was explored for copper and molybdenum between 1969 and 1970.

The area is underlain by mesozonal plutonic rocks 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. Refer to the Lorraine (MINFILE 093N 002) occurrence for additional information regarding regional geology and the Falcon (MINFILE 093N 068) occurrence for local geology details.

The Fal occurrence comprises magnetite-rich gabbro and ultramafic rubble, apparently blasted from now-overgrown trenches on the south side of a south-flowing creek entering Tchentlo Lake near its middle. These rocks reportedly host up to 2 per cent chalcopyrite, although only magnetite is evident in the blasted material. A sample (F89-R-8) of boxwork pyrite mineralization hosted by a bleached intrusive rock taken from the trenches reportedly assayed 1146 parts per million copper and 5.3 grams per tonne silver (Assessment Report 20272, page 10 and Appendix A). A second sample (F89-R-7) of gossanous material hosting 1-centimetre round pyrite, chalcopyrite, and magnetite crystals, taken approximately 300 metres downstream, assayed 4363 parts per million copper, 1457 parts per million lead, 4935 parts per million zinc, 103 parts per million nickel, 10 262 parts per million arsenic and 10.0 grams per tonne silver (Assessment Report 20272, page 10 and Appendix A).

Surface exploration is known to have been carried out in the area of the Bal group from 1940 to 1944; however, no details of this work exist. In 1969, the Bal 1-16 and PJ 1-20 claims were owned by Tchentlo Mines and a soil survey and trenching were completed.

The following is a general work description for the area. Periods of work done on the Fal (OVB) occurrence are indicated.

In 1969, the HI claim group was staked for the N.B.C. Syndicate. These claims were primarily north of and adjacent to the Bal claims (just east of Fal) but were also staked immediately west and south of the Bal (along the shore). Geological mapping, soil geochemistry, ground electromagnetic and magnetometer surveys were carried out in 1969 and 1970. In late 1970, Tchentlo Lake Mines acquired the HI group from N.B.C., the TC group from A.K. Anderson and the J group from R.W. Jackson. Work during 1970 included soil geochemistry, trenching and stripping. An anomalous molybdenum and copper zone was indicated on the Bal 4 claim and extended onto the HI 27 fraction. This is the area of the Falcon prospect (MINFILE 093N 068).

In 1971, Tchentlo Lake Mines changed its name to Nation Lake Mines Limited; later that year they optioned the property to Lomita Mining Corporation, who carried out unspecified work.

Limited deep diamond drilling was apparently done on the Bal group, probably in 1971, based on the presence of old drillcore boxes bearing a 71 prefix on the property.

In June 1981, Placer Development Limited explored the JP 1 claim (later held as the Falcon 3 and in part Tbor) with geochemical and geophysical surveys. The JP 1 claim is located approximately 3 kilometres north-northwest of the plotted Falcon occurrence (MINFILE 093N 068). A 1-kilometre long copper anomaly was outlined by widely spaced sample stations (Assessment Report 9403). A sample of outcrop yielded 0.5 per cent copper. A new MINFILE number was issued for this showing area, (Bor, MINFILE 093 231) based on this assay and the description from Warren’s work in 2000.

In 1981, work on the OVB claim (Falcon 2) by Placer included a heavy mineral soil and stream survey and very low frequency electromagnetic survey. The OVB covers the area of the Fal occurrence. A small number of soil and stream samples were taken over the property (Assessment Report 10077). In 1982, Placer returned to carry out a very low frequency electromagnetic and magnetometer survey over the geochemical anomaly. A coincident magnetic high was partially outlined by the survey.

In 1989, Arthur Halleran prospected the Falcon 1-4 claims (Assessment Report 20272). Independence Mining Company Inc optioned the Falcon claims and conducted a geological and geochemical program in 1990, collecting 690 soil samples (Assessment Report 20825). The Falcon covered the Bal (MINFILE 093N 068) and the Fal (OVB) areas, and in 1990 the group included the Falcon 1 to 6 and the Fal 1 and 2 in the middle of the Falcon 2, east of the Falcon prospect.

In the fall of 1999, loggers excavating a rock pit at 20.5 kilometres on the T-road exposed chalcopyrite, iron pyrite and magnetite mineralization. The Bor and Tbor claims were staked by Lorne and Chris Warren and were prospected in the fall of 1999 (Assessment Report 26451). The Tbor covers part of the JP-1 of Placer and the HI claim a few kilometres north of the Falcon prospect.

In 2005, Redton staked and immediately optioned their Redton property to Geoinformatics Exploration Canada Inc. In 2006, Geoinformatics carried out an extensive field program across most of the property, including soil sampling in Redton-South, and followed up with, among other projects, a approximately 8.8 line-kilometre internal polarization and two-hole, 818-metre diamond drill program on the Falcon prospect (MINFILE 093N 068) in 2007 (Assessment Report 32504).

In 2007, Geoinformatics Exploration Canada Inc undertook work on its regionally extensive claim group, which covered the Fal occurrence and surrounding area. The two reconnaissance holes both intersected widespread molybdenum and minor copper mineralization hosted in a quartz monzonite porphyry and monzodiorite-gabbro country rocks. The mineralization has a horizontal extent along a section of approximately 380 metres and a vertical depth of at least 300 metres, with both holes ending in significant mineralization.

A subsequent AeroTEM survey in 2012 identified 65 electromagnetic and magnetic anomalies (Assessment Report 32504) and, starting in 2012, the area was explored in conjunction with the nearby Falcon (MINFILE 093N 068) occurrence as a part of the Redton property.
