Mr. John McIntyre reports
NHA 2007 DRILLING PROGRAM RESULTS
On Aug. 6, 2008, Noble Metal Group Inc. received the report of Wayne F. Downey, PGeo, on the tests requisitioned by him concerning the oil shale core samples obtained during the 2007 exploration program on NHA's oil shale permitted lands located near Tisdale, Sask. Mr. Downey, who at the time was the in-house geologist for Global Resource Holdings LLC (GRH), ordered the various tests that were conducted by Baseline Resolution Inc.'s analytical laboratories located in Houston, Tex.
Total organic carbon (TOC) tests measured in weight per cent were carried out on all samples sent to the lab. These samples were taken from seven of the nine drill holes completed. As reported by Mr. Downey, in classifying oil shales, the general rule is to consider TOC values from 0.5 weight per cent to 1.0 weight per cent as fair; 1.0 weight per cent to 2.0 weight per cent as good; 2.0 weight per cent to 4.5 weight per cent as very good; and 4.5 weight per cent to greater than 5.0 weight per cent as excellent.
A total of 88 core samples were tested for TOC. The average results of one hole were in the very good range. The average results on the remaining six holes were in the excellent range with individual samples reaching total organic carbon content maximums of 9.45 weight per cent to 10.95 weight per cent in each of the six holes.
Other tests commissioned by Mr. Downey included a modified fischer assay (MFA) on four of the samples. The MFA tests provide an estimate of potential oil yield. The four samples selected provided a potential oil yield ranging from 5.49 litres per tonne (1.6 U.S. gallons per ton) to 43.9 litres per tonne (12.8 U.S. gallons per ton). Mr. Downey is not qualified to provide an estimate on potential reserves this can only be carried out by a qualified resource engineer.
Rock evaluation tests indicate what is classified as the type of oil or gas formation the source rock comprises. These tests on the samples from the drill holes indicate what is classified as an immature, oil-to-gas-prone, Type III to Type II, kerogen-based source rock. The main hydrocarbon components are solid or semi-solid kerogens and bitumen disseminated through fine-grained, tightly compacted shale.
Mr. Downey estimated that as much as 20 per cent of the hydrocarbons from the formation may have been lost due to pressure release, water flushing and off-gassing during the drilling operation.
The baseline results reported indicate a basis for further exploration of the Tisdale oil shale properties in order to further delineate the deposit.
