The Klastine Plateau limestone occurrence outcrops for 3 kilometres on the Klastine Plateau, approximately 10.5 kilometres east of the village of Iskut and 6.5 kilometres north of Ealue Lake. The Klastine Plateau, a sub-unit of the Tanzilla Plateau physiographic terrane, is marked by strongly incised creek basins.
Mapping of the area indicates that the limestone lens comprises part of the Lower Permian Stikine assemblage and older basement exposed along the southern flank of the Stikine arch. The unit lies within a sequence of lower greenschist metamorphosed phyllites, phyllitic greenstones and ribbon cherts forming tight mesoscopic folds trending to the northwest. Bedding near the centre of the lens strikes 315 degrees and dips 65 degrees northeast.
In 2010, a helicopter-borne Versatile Time Domain Electromagnetic and aeromagnetic geophysical survey was carried out over parts of the Yellow Chris and Red Chris South properties, on behalf of Teuton Resources Corp. A total of 530 line-kilometres was flown with 201.1 line-kilometres attributed to the area including the Klastine Plateau and Kitty (104H 015, located 8.6 kilometres northwest) over the northernmost survey grid, within Teuton's Yellow Chris claims. Total Magnetic Intensity data show a northwest trending group of three discrete, circular to ovate magnetic anomalies along the eastern edge of the Yellow Chris survey grid, coincident with the Hazelton Group volcanic intrusive. The most prominent feature of the Total Magnetic Intensity map is a large, discrete, roughly oblate magnetic high in immediate sharp contact with a strong magnetic low in the southern part of the survey area (Assessment Report 32327).
In 2013, 454 soil samples were taken along traverses overlying various magnetic highs and lows outlined by the previously flown airborne geophysical survey. A few scattered copper anomalies are apparent from the survey data, with results ranging from 4 to 1002 parts per million copper. Sampling failed to identify any major zones of significant gold mineralization, with a few spot highs of up to 380 and 680 parts per billion gold. Arsenic values ranged from less than 4 to 1847 parts per million with five samples over 291 parts per million. Lead returned values of less than 6 to 421 parts per million and zinc ranges from less than 5 to 772 parts per million (Assessment Report 34216).
The 2013, Redhill Resources prospecting and sampling program was carried out to follow up on results from the helicopter-borne magnetic survey conducted by Teuton Resources in 2010. The primary goal of the program was to examine two adjacent areas of magnetic low and high located on claims Yellow Chris 2 and 3. A total of 26 rock (24 grab and 2 float) and 5 silt samples were collected. A few of the collected rock samples returned anomalous values in copper, lead, zinc, silver, and gold. Sample ISK-24 (float) assayed 1470 parts per million copper, 109 parts per billion gold, and 2.7 parts per million silver. The sample represents a fragment of quartz-carbonate vein with 10-15 per cent pyrite, pyrrhotite, limonite, and minor chalcopyrite. The float most likely derives from a gossanous pod approximately 10 by 5 metres in size located in a cliff above. Sample ISK-15 returned 226 parts per million copper, 256 parts per million lead, and 140 parts per million zinc. A few other samples returned slightly anomalous values in copper, gold, and zinc. Silt samples recorded low values (Assessment Report 34422).
