dinnyeberki uranium potential, page-3

More info to digest:

Bore hole Db-46 is whe's, Db3 was one from the 80s. The last point confirms my views on the Dinnyeberki deposit.

"The reason of this
misalignment can be the poor drill core recovery percentage (which was only 35% in some
intervals) and the careless handling of the core by the drilling rig crew.."

"In the lower ore section of the drillhole Db-46, the core sample assays have produced
significantly higher grades than had been expected from the point gamma logs (2869 µR/h
maximum vs. 20,600 ppm U). The spectral gamma-ray tests showed strong positive radioactive
disequilibrium in this zone (RaUeq/U = 0.39).."

"The possible explanation of the current situation is in connection with the former
experimental ISL production. It can be concluded from the report about the ISL site remediation
(KONRÁD et al. 2005) that the deposit was left under acidic conditions for a decade long
(groundwater pH = 1-4). After the remediation had started, the pH was successfully increased, but
slight acidity (pH = 5-6) remained following to the completion of remediation actions. The more
than 20 years of acidity in combination with the limited, but effective groundwater flow resulted in
the rearrangement of uranium mineralization.
Drillhole Db-46 is located within the impact zone of the one-time experimental ISL area.
Uranium has been removed from the middle part of the original ore body, partly in the course of
the ISL production, but partly later, owing to the transportation by groundwater in the acidic
environment. Fortunately, the movement was mainly downward, and the clay and sand of high
organic matter content in the lower ore zone of Db-46 captured the uranium again and bound it.
This is the reason of the negative disequilibrium in the middle (uranium loss, radium surplus) and
the positive disequilibrium (uranium surplus) below."
