- True thicknesses are unknown.
- Ni and Cu tenors were calculated where Sulfur% was greater
than 5. Ni tenor range from 8.39 wt% Ni to 16.35 wt%
(avg 11.83). Cu tenor range from 1.44 wt% Cu to 3.10 wt% Cu
(avg 2.29).
- Tenor is calculated by dividing the Ni ppm and Cu ppm by the
mass fraction of sulfur (S% by partial extraction analysis
divided by the presumed total sulfur possible in a massive
sulphide (36.5%)) and dividing by 10000.
Thisfirst series of drill holes into the Tunerq nickel prospect werelocated according to the only known outcrop exposure with littleassistance from geophysics. The program was designed to gain geologicalinformation such as depth extent of sulphide mineralization below theoutcrop exposure, to obtain fresh unaltered samples for analysis and todevelop a better understanding of the orientation and extent of themafic - ultramafic body that hosts the sulphide minerals. Mafic -ultramafic rocks and more felsic components of the intrusion appear tobe undeformed and are interpreted to be much younger than thesurrounding granodiorite country rock.
The extent of the hostrock appears open; recent surface mapping has revealed that it extendsat least 400 to 500 metres from the discovery outcrop. The nickelsulphide zones have been tested over about 70 metres in a north-southdirection and 75 metres in an east-west direction. The mineralizationis open along strike and down dip. In hole 08TUR002, samples over 1.52metres exceed 2% Ni and are as high as 3.95%. Sulphides range fromdisseminated to net-textured and semi-massive. True thickness of nickelsulphide mineralized zones is not known.
"This is one of thebest series of early stage drill holes that I have seen in nickelexploration," states Bernard Kahlert, Director of Diamonds North. "Thefact that a relatively thin sequence of mafic rocks is so stronglymineralized infers that it has been injected from a nearby largerdifferentiated gabbroic body which will be the future target ofexploration at Tunerq."
Additional geophysical surveying willbe conducted. Electrical geophysical methods suitable for targetingnickel sulphides are being considered and a survey is expected to startshortly. Upon completion of the geophysical survey, additional drillingusing a core drill is being planned for later this summer. Plansinclude testing mineralization down dip and along strike. Deeper holesmay also be drilled to test for multiple zones of mineralization.
Initialmapping was conducted in May with extensive snow cover which hindersvisibility of outcrop exposures. Additional mapping is planned to beginshortly now that the snow has melted.
Detailed geological descriptions of the reverse circulation drill cuttings collected from Tunerq are provided below.
08TUR001was drilled vertically at the centre of the Tunerq discovery outcrop.This hole was intended to test the depth extent of the Ni-Cumineralization observed at surface and obtain fresh unaltered samplesfor assay. The hole collared in pyrrhotite-chalcopyrite mineralizedgabbro and ultramafic continuing to a depth of 24 metres.Mineralization varies from a few percent to 20-25% pyrrhotite withaccessory chalcopyrite. The overall interval grades around 8-10%pyrrhotite and 1% chalcopyrite. Pyrrhotite occurs as fine graineddisseminations within the phlogophitic gabbro and as more abundantnet-textured interpyroxene/olivine zones over short distances.Chalcopyrite occurs within the gabbro, and plagioclase-richsegregations in the gabbro and late crosscutting granitic rock. Thegabbro and ultramafic rocks are interlayered. The ultramafic rocks aremore strongly mineralized. Granodiorite was encountered 24 metres andcontinued to EOH at 66 metres.
08TUR002 was drilled at a dip of-60 degrees to the east approximately 12 metres east of 08TUR001. Itwas intended to test the eastern extent of the Ni-Cu mineralizationobserved at surface. The hole collared in pyrrhotite-chalcopyritemineralized gabbro and ultramafic which continued intermittently to adepth of 35 metres. Mineralization varies from a few percent to 50-70%pyrrhotite and 5-8% chalcopyrite. The best intersections occur between27 and 34 metres and contain visual estimates up to 50% pyrrhotite and3-5% chalcopyrite. Individual chips can contain as much as 75%pyrrhotite and chalcopyrite. Pyrrhotite occurs as fine graineddisseminations within the phlogophitic gabbro and as more abundantnet-textured interpyroxene/olivine zones over short distances.Chalcopyrite occurs within the gabbro as well as late crosscuttinggranitic rock. The gabbro and ultramafic are interlayered. Theultramafic rocks are more strongly mineralized. Granodiorite wasencountered 59 metres and continued to EOH at 70 metres.
08TUR003was drilled toward the south at a dip of -60 degrees approximately 17metres from 08TUR001 with the intention of testing the southern extentof the Cu-Ni mineralization identified at surface and in RC hole08TUR001. The hole collared in mixed granodiorite-granite followed byan intersection of gabbro and ultramafic rocks (7-28 metres). Nosignificant mineralization was encountered. Granodiorite began at 93feet and continued to EOH at 34 metres.
08TUR004 was drilled ata dip of -60 degrees to the west approximately 12 metres west of08TUR001. It was intended to test the western extent of the Ni-Cumineralization observed at surface and in hole 08TUR001. The holecollared in pyrrhotite-chalcopyrite mineralized gabbro and ultramaficrocks which continued to a depth of 5.8 metres averaging 25% pyrrhotite& 1% chalcopyrite. Weak disseminated pyrrhotite-chalcopyritecontinues to 11.3 metres followed by granodiorite to EOH at 19.5metres.
08TUR005 was drilled at a dip of -60 degrees to thenorth approximately 19 metres north of 08TUR001. It was intended totest the northern extent of the Ni-Cu mineralization observed atsurface and in hole 08TUR001. The hole collared inpyrrhotite-chalcopyrite mineralized gabbro and ultramafic whichcontinued to a depth of 18 metres averaging 8-10% pyrrhotite &0.5-1% chalcopyrite. Weakly mineralized gabbro occurs between 18-30.8metres. The best mineralization occurs between 10-15.5 metresconsisting of 15-25% pyrrhotite and 2-3% chalcopyrite. Granodiorite wasencountered at 30.8 metres and continued to EOH at 34.8 metres.
Twoadditional holes were drilled to test a magnetic high feature. Relativeto drill hole 08TUR001 both holes 08TUR006 and 08TUR007 were drilledapproximately 100 metres northeast and 50 metres north, respectively at-45 degrees dip to the west. A drill thickness of the ultramafic bodyat this location is 46 metres. Disseminated sulphides are present inthe hole, however, no significant concentration were intersected inthese two holes.
The samples were collected using a reversecirculation drill. Each 1.52 metre drill intercept was collected in 20litre containers, homogenized and poured onto a table along a straightline. The sample was split and quartered. One quarter of the sample wassubmitted for analysis. A duplicate sample was submitted every 5samples. Drill cuttings were logged in a secure on-site facility.
Allsamples were analyzed at ALS Chemex (ALS Laboratory Group-MineralDivision) in North Vancouver, BC. ALS Chemex is accredited by the QMIQuality Registrars to ISO 9001:2000, and by the Standards Council ofCanada to ISO 17025. A standard aqua-regia digestion and ICP-AESpackage was used on all samples. Ore grade assays were analyzed byAtomic Absorption.
