BRADY POLE LINE - COBALT - Something of Interest -
Was just sifting through the ( 848 page ) True Claims Report -
Looking for any high values of nickel or cobalt trying to match a geology with the spikes.

COBALT - 1180 ppm = 1180 grams =
0.118% Brady's PoleLine Property. This is a
massive sulphide sample containing about 55% pyrite, pyrrhotite with minor chalcopyrite. The host rock is quartzite. 20% of the sample is composed of a large carbonate vein which has soome larger blebby sulphide pods. The strongest mineralization occurs in a band along the contact of the vein with the host rock. Massive pyrite with gray quartz pod contained within very coarsely crystalline Iron carbonate

OTHER SAMPLES AT BRADY ? There were 2 more good cobalt values at - Brady Pole -
H 820151 - 487 ppm - cobalt Brady's PoleLine Property, This rock contains quartz, ankorite, pyrite, pyrrhotite and hematite. It is strongly oxidized and contains about 15% sulphides. Some parts of the sample contains fragments of highly chloritic material that are strongly foliated. Looks like some areas have become brecciated and infilled with a sulphidic matrix. Quartzite fragments also contain disseminated sulphides. Transluscent clear to milky quartz with 10- 60% locally of medium to finely crystalline pyrite, pyrite forms blebs and net texture between quartz, contains areas of voids from past carbonate dissolution. Host rock is a light gray sericitized bruce formation
H 820152 - 306 ppm - cobalt Brady's PoleLine Property. This sample is of a very coarse grained quartzite with carbonate composing about 50% of the rock. 5% pyrite and pyrrhotite are observed within the quartzite. The sample is strongly oxidized. Mottled brown tan medium crystalline, granoblastic, 55% slightly gray-white quartz, 40% flesh coloured ankerite with 15% interstitial pyrite. Ankerite on weathering produces a rusty brown soft earthy material. Some chalcopyrite may be present.

What's a good cobalt grade ?
Cobalt grades above 0.1 per cent are considered economic at current cobalt prices. Grades above 0.2 per cent are average and grades of 0.3 per cent and above are considered very good, especially with scale.Mar 21, 2018

while 51 and 52 were not as intense with sulphides.
but... still in the Brady Pole line area.
and at the contact point of chloritics - not in the chlorite zone... moreso... sulphides and carbonate quartz.
Cheers....
