The claims are underlain by Lower Cretaceous Kitsun Creek Formation sediments of the Skeena Group comprised mainly of greywacke, sandstone and shales. The sediments are intruded by a Late Cretaceous to Eocene granodiorite stock and associated porphyry dikes which exhibits propylitic alteration, mainly sericite, silica, minor epidote, chlorite and kaolinite. The Skeena sediments near the contact with the intrusion are hornfelsed and host disseminated pyrite.
Mineralization is found throughout the sediments as disseminated pyrite with blebs in the fractures and along schistosity planes. Some molybdenite an minor chalcopyrite occur along fractures and in quartz veins in the intrusive and hornfels (refer to 093L 136- Reiseter 5).
On the Reiseter property there are seven known parallel veins structures within shear zones that strike north-northeast and dip moderately to the east. The veins range from 7.6 to 25.5 centimetres in width and host stibnite with some sphalerite, galena and minor chalcopyrite. Approximately 1.5 centimetre rock fragments are cemented by sulphides and quartz. The veins characteristically have sharp contacts with the silicified siltstone.
The number one vein, located between 760 and 790 metres elevation, has been developed by a series of pits and trenches over a strike length of 145 metres and varies in width from 15 to 60 centimetres. In the northern most pit stibnite occurs mainly as coarse-grained tabular crystals with finer material occurring along the hangingwall. In 1970, a grab sample from this vein assayed 4.0 per cent antimony and trace gold. A chip sample taken across 60 centimetres including the quartz vein material and host rock, assayed 2.2 per cent antimony with trace gold (Geology, Exploration and Mining in British Columbia 1970, page 163).
In 1970, 19 tonnes of high grade vein material from the number one vein was shipped from this property. From this, 6302 kilograms of antimony were recovered.
The Reiseter 4 and the Reiseter 5 (093L 136) are contained within a geochemically anomalous soil zone developed in the mid-2000s to 2011. By 2011, the main Reiseter anomalous zone was defined by MMI soil geochemical sampling and found to have dimensions with a minimum of 1200 meters in a westerly direction by 800 meters in a northerly direction. The recent work has shown the strike to be west-northwesterly with it being open to the west-northwest. It is a polymetallic anomaly with anomalous values mainly in molybdenum, arsenic, zinc, lead, silver, gold, cadmium, and copper.
The vicinity of the Reiseter 5 was also prospected in 2011 but only slumped trenches were found. The Reiseter 5 and the Reiseter 4 (093L 134) are contained within MMI soil grid area.
WORK HISTORY
In the mid-1950s, Anthony Mesich of Smithers, B.C. first discovered antimony, lead, zinc, and silver on the area presently covered by the Reiseter claims. Mr. Mesich had held six key claims from 1957 to 1973. During this period considerable work had been completed on the property, mainly oriented at developing high-grade antimony veins, by Mr. Mesich and three companies holding the property under option. A limited amount of vein material was washed and cobbed from surface pits for metallurgical testing.
In January, 1972, Channel Copper Mines Ltd., N.P.L. optioned the property from Mr. Mesich. Dr. W. R. Bacon, consultant for Channel Copper, recognized the potential of the property for a low-grade molybdenum or copper/molybdenum porphyry deposit, and in a report dated January, 1972, recommended further exploration oriented at discovering this type of deposit. The May/June, 1973, period completed the first phase of this program. The work comprised 12 lines of Induced Polarization Surveys totaling 8.85 kilometers. The IP survey used the dipole – dipole electrode array with 100-meter electrode intervals and three separations (n=1, n-2 and n=3). This work delineated an open-ended, 900-meter long and 300-meter wide IP anomaly.
In 1973, Channel drilled two holes totaling 266 meters on the present – day Rieseter property. The locations of these holes are shown on figure 13. Drill hole R-73-1 intersected altered greywacke and a thick section of granodiorite. Drill hole R-73-2 intersected siliceous greywacke throughout. Both holes encountered quartz veins with minor amounts of pyrite and trace amounts of molybdenite. Although the logs refer to samples, no assay results were subsequently reported.
Mapping in 1988 uncovered an old trench which hosts blebs and disseminated pyrite in quartz stockworks within siliceous sandstone. Sample APE 88-25-1, taken from a quartz vein with pyrite assayed 6.84 grams per tonne gold, 218.0 grams per tonne silver and 0.087 per cent copper. Sample APE 88-25, taken across the vein including some country rock, assayed 0.002 gram per tonne gold, 0.007 per cent copper and 0.001 per cent zinc (Personal Comments: P.A. Desjardin, Fieldwork, 1988). This sample formed the data that was part of the deleted MINFILE occurrence Reiseter (093L 135); the plotted location is very close to that of Reiseter 4 (replotted in 2014).
Double Crown Ventures acquired the property in 2007. In June, 2010 they contracted Geotronics Consulting Inc. to carry out an MMI soil sampling survey and a test IP Survey. The MMI survey consisted of 284 samples along 8 north-south lines, for a total survey length of 7.35 line-kilometers. The report, summarizing the results of the MMI survey, identified several highly anomalous results. Two lines (L16800 E and L17000 E on Figure 11) of IP surveying, totaling 2.2 line-kilometers, were also done during this time. The time domain mode was utilized. The dipole length and reading interval was 25 metres read up to 12 levels.
The MMI soil sampling revealed a lead anomaly up to 72 times background on both lines appearing to strike in a west-north-west direction for a minimum strike length of 700 metres and an approximate true width of 500 meters. In addition, anomalous values in zinc are up to 47 times background was noted. Finally, the MMI survey revealed elevated values in silver up to 8.7 times background. Copper and cobalt values were lower than over the rest of the two lines. However, the cobalt is anomalous at the east and west edges of the lead anomaly. The cobalt may indicate pyritization surrounding the possible lead and zinc mineralization.
Double Crown Ventures optioned the Reiseter Property to Golden Tiger Minerals Inc. on February 3, 2011. Golden Tiger carried out a program during the summer of 2011 that consisted of MMI soil sampling (111 samples) with the purpose of detailing the known anomalies, 10 line-kilometers of IP/resistivity surveying, 25 line-kilometers of magnetic surveying, and a six-day geological mapping program. Most of this work was carried out on the Reiseter Grid, but a small amount of sampling was done on the Bulkley Grid in order to locate a historical zinc anomaly. A geologist visited the property and prospected in the Reiseter 4 (093L 134) area, locating a showing a few hundred metres east and sampling it (Dupre and Payie, 2013). The vicinity of the Reiseter 5 was also traversed in areas and slumped trenches in the vicinity of the Reiseter 4 area. The Reiseter 5 and the Reiseter 4 are found within MMI soil grid area.
Golden Tiger Minerals Inc owns seventeen of the mineral claims (2787 hectares) while Double Crown Ventures Inc. owns the remaining four claims (1710 hectares) of the Reiseter Property and these may be acquired by Golden Tiger under an option agreement. Subsequent to 2011 Golden Tiger Minerals Inc and Datum Ventures Inc entered into a Letter of Intent wherby Golden Tiger would be acquired by Datum Ventures Inc.
