The RDN property covers a felsic centre which lies near the top of the Early to Middle Jurassic Hazelton Group. Variably altered dacitic to trachytic volcanics and subvolcanic intrusives, with lesser rhyolite, are overlain by carbonaceous, pyritic argillite and pillow basalt.

Surface float samples of pyritized argillite at the Jungle zone graded up to 25.4 grams per tonne gold (http://www.rimfire.bc.ca/s/RDN.asp).

A 100 x 450 metre Au+As+Ag+Pb soil geochemical anomaly (the Jungle Anomaly) is underlain by a fault-bounded package of fine marine elastics, rhyolite and mafic volcanics, between Gossan and Downpour Creeks. Backhoe trenching in 1998 failed to reach bedrock, but near-source colluvium in the bottom of the trenches confirmed the soil anomalies. Gold-bearing float cobbles included silicified/veined argillite and silicified/veined rhyolite; the rhyolite is chemically distinct from any lithologies previously sampled in the Downpour Creek area. A cobble of pyritic argillite with quartz stockwork was sampled in 1997 from the trenched area, assaying 26.44 grams per tonne gold (Assessment Report 25813). Pyritic chert float, possibly representing a silica-pyrite exhalite, was found in the southwestern, untrenched portion of the Jungle Anomaly. The coincidence of rhyolite, possible silica- pyrite exhalite and gold soil geochemistry support the potential for Eskay-style VMS mineralization in this area, although structurally-controlled mineralization cannot be discounted.

Drilling in 1999 was abandoned due to technical problems before reaching target depth although elevated gold values occur throughout lower mudstone package including 1.1 metres of 5.19 grams per tonne gold (www.rimfire.bc.ca/s/RDN.asp). Further drilling in 2002 was unsuccessful in reaching the target horizon.

In 2004, a single drillhole in the Jungle zone reached a depth of 336 meters entirely within argillite, siltstone and minor mafic volcanic rocks thought to be correlative with the hanging wall sequence at the Eskay Creek deposit. The drill hole was designed to test strong Au+As+Ag+Pb surface geochemistry but did not return any values of significance and passed from intermediate volcanic and sedimentary rocks into a thick, monotonous turbiditic sedimentary sequence.
