A response to my picture question. Darcy response to alibongo888 tweet of my post
My response to darcy.
Thanks for the information. I agree on the brownish stuff being sandstone.
In terms of the size of the core boxes I see at least 5 boxes with each box narrowing the sandstone interval from left to right.
I was estimating that the WIDTH of the box is 4-5 feet wide. I count roughly 15 core samples of the browninsh stuff in one of the boxes which when multiplied by 4 feet gets me 60 feet of sandstone. As such, I feel these are newer drill cores. As for the stuff below the sandstone, I have no idea what it is but this is what the Christie Lake geology reported in the past.
Geology and Mineralization The Christie Lake Project is located in the south-eastern Athabasca Basin, underlain by late Paleoproterozoic Manitou Falls Group sandstone, conglomerate and mudstone. The shallowly dipping sandstones of the Athabasca Basin lies unconformably upon Archean granitic gneiss and early Paleoproterozoic metasedimentary gneiss rocks of the Wollaston Domain. The project lies within the western part of the Wollaston Domain, which is part of the Cree Lake Mobile Zone of the Trans-Hudson Orogen. Unconsolidated Quaternary glacial and periglacial deposits, consisting of ground moraine, esker, drumlin, outwash, aeolian and lacustrine sediments, effectively mask most of the bedrock in the area and can form a cover up to 90 metres thick.
The Paul Bay, Ken Pen, and Orora uranium mineralized zones are located in the northeastern part of the property, in mineral disposition CBS-8027. The northwest part of the project area is cut by the Yalowega

Trend Fault, interpreted as an extension of the P2 Fault that hosts the uranium deposits at the McArthur River Mine.
In the eastern part of the basin, where the Christie Lake Project is located, the Athabasca Group is represented by the Manitou Falls Formation and is an approximately 400-metre thick sequence of quartz arenite sandstone with minor conglomerate beds and trace mudstone beds.
The Wollaston Domain is a northeast-trending fold thrust belt composed of remobilized Archean basement and overlying Paleoproterozoic supracrustal sequences of the Wollaston Supergroup. At Christie Lake the hanging wall lithologies of the Wollaston Domain are mostly semi-pelite paleosome with intervals of pegmatite textured neosome. The footwall lithologies are more quartz-rich composed mainly of psammite and quartzofeldspathic gneiss. The base of the hanging wall is characterized by an interval of graphitic pelite, oftenfaulted, that is spatially related to uranium mineralization.
The Paul Bay Zone is an 80-metre-long mineralized body that plunges for at least 200 metres to the southwest from the unconformity and follows the dip of the faulted Lower Wollaston Domain graphitic metasedimentary rocks characterized by an interval of graphitic pelite. The Ken Pen Zone is approximately 260 metres to the northeast from the Paul Bay Zone, striking in a northeast direction concordant with the Yalowega Trend Fault.
Ken Pen plunges about 80 m into the basement from the unconformity with a plunge that is similar to Paul Bay. The Orora Zone is located approximately 360 m northeast of the Ken Pen Zone. Orora uranium mineralization manifests dominantly at the unconformity, approximately 420 metres below surface and can extend up to 40 metres into the basement rocks along the Yalowega Fault.
The mineralized zones along the Yalowega Trend are associated with intense fracturing and brecciation and have a bleached argillic alteration halo extending up to 35 metres above the mineralization. The best uranium mineralization is associated with breccias in the lower part of the Yalowega Trend Fault Zone. Alteration haloes associated with the mineralized zones at Christie Lake are typical of Athabasca Basin uranium deposits and are dominated by silicification, hematization, precipitation of drusy quartz and illitization with massive quartz dissolution and intense fracturing. In the basement rocks the alteration typically consists of hydrothermal illitization, chloritization and the development of dravite, which is superimposed upon and commonly obliterates the paleo-weathering profile. The alteration styles at the Christie Lake Project are found as haloes around the mineralized zones.
Other than the pelites and gneiss I'm not sure if that report matches up with your assessment. Sandstone is easier to identify in a photo much like visible gold in quartz is. But the stuff in this photo, for me at least, is not possible to assess. So thanks for your input.
That said, this is that part where armchair miners such as myself are best to leave to the experts. However, I suspect that these are core samples taken from the current drill program at Christie Lake and I notice that shortly after this picture was tweeted out by UEX, the UEX share price rose slightly for a few days (Aug 30 to Sep 6). But then so did other Uranium stocks.
Thanks again for the input Darcy and thank you Alibongo888 for passing it onto twitter. I many just have to set up an account myself. Just not ready yet.
