This page below is focused on the Ogoki diamond project.
This company also has exploration potential across multi-commodities and projects and some of those are highlighted on this blog as well..
Now onto the diamonds below.
---------------Update October 14th, 2020-------------------------------
There has been a bit of focus going forward for a planned (not guaranteed) winter drilling program.
Of the targets, the initial focus will be on K5 and K12. What do we know about these?
We could visually see a circular impression on the K9 target above the River. What about K5 and K12.
When loading up on google maps, it sure looks like K12 will fall in the same boat. A circular depression at surface?
Here is the image:
K12 has a bit of a tail on the SE corner of the anomaly. The image does clearly show a circular impression. Looks like natural water drainage picking a path nature chose for it. It lines up pretty good with the anomaly plus it does look like a bit of a tail as well.
It is showing very similar to what K9 highlighted. Impressions at surface.
What about K5?
Here is the image:
This one doesn't have an obvious circular impression for the anomaly itself. The broader area on the geophysics (green in the image) does seem to align with a shape that encompasses a couple of rivers and a change in surface structure. The K5 anomaly also comes with a string of pearl anomaly to the SE of it. The combined anomaly could influence the surface in a larger capacity.
These will both be the initial focus of the drilling campaign....any success should influence very near term decisions in the field. If K12 hits kimberlite, K13 is very close and could be drilled off. K12 does have the larger tonnage factor, so is the initial preference. If K5 comes up, you could drill another hole that aligns with the pearl. You could also move to K6 nearby.
K8/9/10 are near the major river (not small) with embankments, etc. Which just adds another set of logistics. (present and future).
Things appear to be lining up for a DDH to mobilized for drilling on frozen ground in January to February timeframe.
Question is whether Mother Nature will also align and uncover some ancient volcanoes.
---------------Update May 31st, 2020-------------------------------
Now that we found details on the borehole KIM samples, a quick search to see if their is any historic iceflow directions.
This is a bit further SW, but it does show the direction.
Here is the link to the article -- Iceflow directions
...and here is the resulting image:
Again, this is further SW, but if we map out the arrows on our map that includes the anomalies and the 2 locations of the KIM Samples, this is what we get:
These ice flows were mapped in circa 1965. There may be something further NW.
Given the information we know, having the KIM samples get swept to the SW, makes sense given the direction of the ice flows.
---------------Update May 27th, 2020-------------------------------
I found the missing appendix...will dig into it to see if I can find the useful samples in question.
Here is the link -- Website with documents
If the link doesn't work, here is the parent site -- http://www.geologyontario.mndm.gov.on.ca/mndmfiles/afri/data/records/20000007975.html
Here is the resulting image:
The two boreholes that sampled the highest amount of kimberlite indicator minerals yielded 5 KIM's each. They are highlighted in the photo with a few other minerals. These are in location to the GSH targets by about 50 km's. The key point here is that the overburden means there are very little KIM's to be found anywhere and there is no chance of an outcrop. These KIM's actually came from shallow borehole and the KIM's themselves were probably placed there a very long time ago. Could these kimberlite indicator minerals originate from ancient volcanoes 50 km's to the NE? This bring in a bit more optimism when a drill finally gets put into a couple of these anomalies.
----------------------------------------------------------------------------
This just came onto my radar recently as a junior company with potential kimberlite targets.
Property is called Ogoki and the company recently received permissions from the local First Nations to be able to drill in and around the area.
Timeline:
2009 to 2015 -- Prospector (and/or Geologist) works through the area and stakes several claims.
2017 -- Claims are sold as a package to Golden Share and the company also brings on the geologist to become the new CEO.
2019 -- Agreements reached with local First Nations -- Company also receives drilling permits from government agencies. The company will need to raise some money to drill.
Targets:
Nothing like a photo or two to show the targets that may or may not contain kimberlites.
If you look at the K9 target on google maps, there is a slight circular depression visible.
That target in the photo above on K9 represents a 70 hectare anomaly.
This is the number one reason why it deserves a place in this blog. These targets are huge as compared to any other junior exploration project.
These are targets are also about 200 kms SW of the Victor Mine.
Next steps:
A bit unknown here...but with drilling permits in hand.
1 -- Raise money (flow through and other)
2 -- Procure drilling contractor/etc.
3 -- Execute drilling program on priority anomalies
4 -- Look at Core. If kimberlite, send to lab for processing.
What year? 2019? 2020? 2021? That is a question that I have no answer for. The market can be fickle at times. This year, the diamond juniors have been able to raise some coin. Maybe not to their advantage...but still successful. We will see.
Geology:
I was thinking that kimberlites in Canada are all on the Archean base rock. That is not correct.
Here is an image showing the Victor mine in Phanerozoic base rock. Still within the craton...but not in archean.
(reference - Page 2-- Craton)
In the map above, Victor lies in the grey area, so the question is whether GSH's targets lie within the grey area too or sneak into the Archean map.
I downloaded a map from the government of Ontario and found a layer that seems to show the boundary on the phanerozoic and the archean rock. This is an ARC GIS file with a layer called 'geolines'. The area on the top with a lot less noise seems to map reasonable well with the grey area above, so I think that is a good mapping to confirm where the GSH's targets area located.
Zooming into that area, I have highlighted where the GSH targets are in relation to the geology and also the victor area kimberlite pipes. There is also a group of kimberlites west of the victor mine that is in the area as well.
The main victor pipe (2 coalesced pipes) are in the 14 hectare size range, so being that these targets are that large and larger, and also in the same geology should help the already insurmountable odds just a little bit.
I do have a bit of information on that nearest kimberlite find and need to do a bit of research to see where/when/who/etc. on that DDH in that area and exactly how far is it from the current targets.
This is the information:
K1 - Kyle Lake No.1 DDH 95-06
Kyle-1
Found a map with the Kyle pipes on it care of Debut Diamonds -- http://www.debutdiamonds.com/docs/wp-content/uploads/KYLE-Project-Location-MAP1.jpg
Here is the map above and you can see that the distance is about 100 kms from a known Kyle pipe to the GSH targets.
On a satellite image, you can actually see where the phanerzoic bedrock is and clearly these targets are within it.
Boreholes:
Back in 2010 to 2012 - A borehole program was done for a Ring of Fire corridor.
There was sampling done for kimberlites and this was the result:
"Kimberlite Indicator Minerals occur throughout sample area in low abundance (Appendix 7, Figures 1-10) The highest number of kimberlite indicator minerals per sample is 5 and occurs in samples 4210 (8-9b) and 2939 (4-9).
The average number of Indicator minerals per sample is 1. In general the results do not show any areas that represent obvious targets for follow up work. However there are Indicator Minerals in the study area with chemistry consistent with diamondiferous rocks and if follow up work where to take place these areas should be prioritized. "
Here is the map of the Boreholes that at one point are about 30 km's away from the target anomalies.
This was obtained from this document -- http://www.geologyontario.mndm.gov.on.ca/mndmfiles/afri/data/imaging/20000007975/20011930.pdf
and this document:
http://www.geologyontario.mndm.gov.on.ca/mndmfiles/afri/data/imaging/20000007482/20010941.pdf
So, there are indications of kimberlites (very spread out and in low quantities) across the landscape. There is not enough concentrated in one area to give any hints of source.
Diamond Potential in the area:
In May 2010, a paper (Diamond Paper) was released that showed where the potential of diamond in Ontario exists and where exploration should focus.
Zone #2 -- Trans-Superior Techtonic has GSH within its boundaries.
Here is a map:
This adds another bit of de-risking to the odds of finding kimberlite and maybe even a diamond mine.
Nearest pipes:
Kyle #1 is the closest pipe to this area.
Here is a great image of the location of the kyle pipes.
This is obtained from page 4 of this document -- KWG_PDF
But does Kyle #1 have diamonds. The answer to that is yes.
If you read the document above, you will see that the diamond grade ranges from 0.3 cpt up to 8 cpt in certain areas of the pipe.
What about size of these Ogoki anomalies? Is K9 really a 70 hectare target?
Let's look at the history of Kyle #2
Here is a snippet from the same link above:
"The heli-mag survey outlined an 800 m diameter, fairly circular, very intense anomaly. On the ground, the anomaly is 300 nT above background. Modeling of the ground magnetic data indicates an 85 m diameter body at a depth of 42.5 m."
You will see that the original heli-mag outlined an 800 m diameter, fairly circular, very intense anomaly. This would imply a 50 hectare target. But on closer look, the indicated diameter of the kimberlite body is at 85 metre diameter, 42.5 metre down into the earth...which implies 0.6 hectare actual body.
What about Kyle #4?
Here is another snippet:
"The heli-mag survey outlined a 800 m diameter, almost circular isolated magnetic anomaly with a weak tail to the east."
...and the follow up modeling:
"Computer modeling of the ground magnetic data resolved a 93 m diameter body at a depth of 115 m."
So at 115 depth, the area is roughly 0.7 hectares in size from the original surface heli-mag at 50 hectares.
What about diamond content in the kyle pipes:
The good news is that all 5 pipes do have diamonds in them. Here is a quick summary:
Kyle #1 - diamonds -- significant amount of diamonds
Kyle #2 - diamonds -- very minor amount.
Kyle #3 - Diamonds -- significant amount of diamonds
Kyle #4 - diamonds --- minor amount.
Kyle #5 - diamonds -- very minor amount.
So, the massive size of the mag anomalies (70+ hectares) for these targets at Ogoki should not negate the opportunity for kimberlite discovery. The mag surveys will be downsized into a computer model and drilling to a more realistic kimberlite pipe size. Anything above 1 hectare would be a great find.
There seems to be significant amount of overburden at the kyle pipes, so a drilling program would probably need to reach at least 100 metres per hole to find kimberlite....and that clearly also indicates that outcropping at surface is a basic zero possibility and finding kimberlite indicator minerals on surface would be tough.
A couple of the kyle pipes did reference dyke type shapes, so that could easily be what we are seeing in some of the mag surveys with Ogoki. K8/K10 seem a bit elongated. They could be dykes.
The diamond content of the kyle pipes may also indicate a reasonable possibility that if the Ogoki anomalies are kimberlites...that they will actually contain some diamonds as well.
The kyle pipes are also in the same #2 corridor of the image that shows the Trans-Superior Techtonic zone.
