GEO - grades by visual then sends off to lab That's the grading format i read in GEM's 43 101 for Berkwood.
Perhaps a change is needed ?
Lot's of carbon / carbon family / graphite could be missed by visual grading.
Especially if peers account for lower grades - down to 1.78% Cgr.
Next up....
Zone 6 has been worked over for the past few years.
I'm seeing a rough estimate of,
700m strike ( horseshoe ) x about 100m wide.

Press Release
Shows maps of each drill campaign of zone 6.

Let's focus on this image ( drill yr class 2022 )
Zomm in to each drill core listed below
Stripped land to identify graphite at surface.
My eyes see the dark graphite middle of stripped areas.
BK6 22 25 - beginning of drill hole has to pass through graphite seen at surface.
Yet... drill log intercept for BK6 22 25 in press - hits at 9m
Issue ? it's seen as green marker on opposite side of, visual surface vein ?
1.8m intercept with only 2.29 Cgr ?
Drill company went through vein which appear to be several meters wide.
In fact if the drill placement was shifted N/E few more meters it would intersect
a far wider section of the surface vein.
That's just analyzing ( 1 ) drill hole.
How many are like this ?
In addition to.... Geo visual grading + not factoring lower grade Cgr.
BK6 22 23
passes right through the vein ( inline ) and no indication of, intercept on - drill line.
in fact... look to the right of this hole... far darker graphite at surface but 22 23
chose a lighter ore color placement ?
If these graphite veins are moreso... at surface.
A series of shallow drilling passing through each and direct vertical
would quickly assess each zone.
Look botton " center " of photo.
Far more graphite veining ( not drilled ) vs drillers chose different drill placements.
Could there be longer intercepts if.... geo factored,
- drill passing through surface veins ...?
- lower grade intercepts factored ?
- lab assaying error ?
3D MAPS ARE NEEDED
One Map of Berkwood = all historical + new holes + intercepts 2% Cgr to highest grade
One map all drill holes Zone 6 - intercepts 2% Cgr to highest grades
Recheck
Berkwood and Zone 6
comparing surface visual veining in photos vs drill core intercepts
Maybe there are many holes that ( visual grading ) did not send off to lab assaying.
Hey.... i like what GEM has in, graphite.
Just want to see max value for each drill meter.
Cheers....
