Continental Nickel Intersects 2.03% Nickel and 0.42% Copper Over 31.5 Metres at Sleeping Giant Zone and Provides Drilling Update, Nachingwea Property, Tanzania
TORONTO, ONTARIO -- (Marketwire) -- 09/13/11 -- Continental Nickel Limited (TSX VENTURE: CNI) ('CNI' or the 'Company') is pleased to report that assays are now starting to be received from the drilling program that commenced in mid-June. Highlights include drill hole NAD11-234 which intersected Sleeping Giant mineralization grading 2.03% nickel and 0.42% copper over 31.5 metres from within a wider interval grading 1.62% nickel and 0.36% copper over 47.0 metres. This intersection represents one of the best sulphide intersections to date at Ntaka Hill and is located 200 metres south of the drill hole NAD10-220 which intersected 2.58% nickel and 0.41% copper over 23.3 metres in 2010. The project is a 75:25 joint venture between CNI and IMX Resources Limited ('IMX') of Australia.
The Company is implementing a CDN$8.775 million work program on the Nachingwea project in 2011, including CDN$5.525 million for exploration and CDN$3.25 million for technical studies to 1) expand the current Mineral Resource of the Sleeping Giant zone; 2) advance the Ntaka Hill nickel-copper sulphide deposits towards mine development and 3) generate and explore priority targets on the regional land holdings. The work program includes approximately 14,000 metres of diamond drilling at Ntaka Hill to extend the Sleeping Giant zone by step out drilling on 100 metre centres, test several other priority targets within the Ntaka ultramafic intrusion and provide metallurgical samples for the scoping study.
The 2011 drilling program, utilizing two diamond drill rigs, began on June 15th with 5,495 metres completed in seventeen holes to late August. Sixteen holes have tested the Sleeping Giant zone and one 2008 drill hole was deepened to test an exploration target south of H zone. Initial drilling on the Sleeping Giant zone experienced technical problems resulting in general delays and several holes not reaching target depths. These issues have been resolved.
Assay results have been received for the deepened hole south of H zone and one of the Sleeping Giant drill holes. Partial assay results have been received for three additional Sleeping Giant holes. Assay results received to date, as well as location and geological context for the seventeen holes noted above, are reported herein and provided below in Table I. A drill hole location figure may be viewed using the link provided with this release.
Patricia Tirschmann, VP Exploration, commented on the drilling program to date 'Each new drill hole is providing valuable information on the nature, extents and structural control of the Sleeping Giant zone. The recent intersection in hole NAD11-234 further enforces our interpretation that a higher grade core to the zone exists and can be traced over a strike length of at least 500 metres from drill hole NAD10-226 in the north to hole NAD11-238 in the south. The 2011 drilling is expected to result in extensions to both the higher grade and lower grade portions of the Sleeping Giant zone. In addition, we continue to intersect zones of disseminated sulphide mineralization which lie above the Sleeping Giant zone within areas designated as 'waste' in the pit shell defined by the April 2011 Mineral Resource.'
Sleeping Giant Zone
Section 3600N
Drill hole NAD11-227 was drilled 100 metres up-dip of hole NAD10-225 and was stopped at 109.2 metres when the core barrel was lost down hole. This hole did not reach the expected depth of the Sleeping Giant zone and up-dip drill testing on the section is still to be completed. Partial assays have been received as shown in Table I.
Hole NAD11-230 was drilled 100 metres down-dip of hole NAD10-224 and intersected various zones of weakly disseminated sulphides within the upper portion of the hole for which assays are pending. A large unit of felsic gneiss was intersected near the bottom of the hole at the anticipated depth of the Sleeping Giant zone.
Section 3500N
Drill hole NAD11-228 was drilled to test 100 metres down-dip of hole NAD10-220 which intersected 2.58% nickel and 0.41% copper over 23.3 metres in 2010. NAD11-228 was stopped short of the Sleeping Giant zone at 382 meters when the core barrel was lost down hole. A number of zones of disseminated sulphide mineralization were intersected including a 59 metre interval from 305 to 363 metres which graded 0.40% nickel and 0.09% copper including 9.05 metres grading 0.63% nickel and 0.12% copper. This wide zone of mineralization may represent the Sleeping Giant zone intersected more shallowly than expected.
Completion of hole NAD11-228 to target depth is planned and will be attempted by setting a wedge near the bottom of the hole in order to drill past the core barrel.
Section 3400N
Drill hole NAD11-229 was drilled 100 metres down-dip of hole NAD10-211 which intersected 1.07 % nickel and 0.19% copper over 19.1 metres in 2010. NAD11-229 deviated off section with the end of hole located approximately 80 metres to the north. Various zones of disseminated sulphides were intersected throughout the hole, the most significant of which were a 14.2 metre interval grading 0.73% nickel and 0.14% copper from 264.2 to 278.4 metres and a 6.95 metre interval grading 0.51% nickel and 0.15% copper from 287.05 to 294 metres. These two intersections are interpreted to correlate with the Sleeping Giant zone, intersected more shallowly than expected as seen in hole NAD11-228. Final assay results are pending for the bottom portion of this hole.
Section 3300N
Drill hole NAD11-231 was drilled to test 100 metre down-dip of drill hole NAD07-023EXT which intersected disseminated nickel mineralization grading 0.64% nickel and 0.12% copper over 80 metres in 2010. NAD11-231 intersected various metre scale intervals of weakly disseminated sulphide mineralization throughout the hole, the lowermost of which correspond to the Sleeping Giant zone. Assays are pending.
Hole NAD11-234 was drilled to test 100 metres up dip of NAD07-023EXT. This hole intersected a wide zone of Sleeping Giant mineralization consisting of disseminated to blebby sulphides as well as partially remobilized sulphide stringers which graded 1.62% nickel and 0.36% copper over 47.0 meters including a higher grade interval grading 2.03% nickel and 0.42% copper over 31.5 meters. NAD11-234 is located 200 metres south of the hole NAD11-220 (2.58% nickel and 0.41% copper over 23.3 metres) and 100 metres south of hole NAD10-216 (1.22 % nickel and 0.21% copper over 15.9 metres). The mineralization in hole NAD11-234 is one of best intersections obtained to date at Ntaka Hill. Final assays are pending for the upper portion of this hole.
NAD11-235 was drilled 100 metres up-dip of hole NAD11-234 and intersected various metre scale zones of disseminated sulphides including a 9 metre interval from 219 to 228 metres which correlates with the Sleeping Giant zone. Assays are pending.
Sections 3200N
Drill holes NAD11-237, 238 and 242 were drilled 100 metres to the south on section 3200N to test for the down-plunge extension of the Sleeping Giant zone. NAD11-237 was lost at 19.65m and was re-collared as hole NAD11-238. NAD11-238 intersected two separate mineralized intervals, including a 15 metre interval from 360 to 375 metres and a 9 metre from 395 to 404 metres, consisting of disseminated to net-textured to stringer sulphides as well as narrow massive sulphide veins. These two intervals are similar in appearance to the mineralization intersected in hole NAD11-234.
NAD11-242 was drilled 100 metres up-dip of NAD11-238 and intersected an 18 metre interval of disseminated to locally net-textured sulphides from 288 to 306 meters which correlates with the Sleeping Giant zone.
Mineralization intersected in holes NAD11-238 and 242 represent an additional 100 metre down plunge extension to the Sleeping Giant zone. Assays are pending.
Section 3700N
Drill hole NAD11-232 was drilled to test 100 metres up-dip of hole NAD11-226 which intersected 2.28% nickel and 0.57% copper over 17.25 metres in 2010. NAD11-232 intersected a 48 metre interval from 143 to 191 metres consisting of disseminated, blebby and stringer sulphides which is interpreted to represent the up-dip extension of the Sleeping Giant zone.
Drill hole NAD11-233 was drilled to test 100 metres down-dip of hole NAD11-226 and intersected a 7 metre interval of disseminated to blebby sulphides from 282 to 289 metres corresponding to the Sleeping Giant zone. This hole also intersected an additional 7 metre interval of disseminated to net-textured sulphides located 150 metres up-hole of the Sleeping Giant zone from 127 to 134 metres.
Hole NAD11-236 was drilled 100 metres down-dip of hole NAD11-223 and did not intersect significant widths of ultramafic rock or mineralization.
Assays are pending.
Section 3800N
Drill hole NAD11-239 was drilled to test for the up-plunge extension of the Sleeping Giant zone and, similar to hole NAD11-233, intersected two separate zones of mineralization. The upper zone consisted of 24 metres of disseminated sulphides from 32 to 56 metres and the lower zone comprised 12 metres of disseminated to blebby sulphides from 212 to 224 metres. The lower zone is interpreted to correlate with the Sleeping Giant zone.
Hole NAD11-241 was drilled to test 100 metres down-dip of NAD11-239 and intersected several zones of disseminated sulphides including a 7 metre interval from 303 to 310 metres which represents the down-dip extension of the Sleeping Giant zone.
Assays are pending.
Sections 3875N
Drill hole NAD11-240 was drilled to test a bore hole EM anomaly located down-dip of L zone and also to test for the up-plunge extension of the Sleeping Giant zone. This hole intersected several zones of disseminated sulphides between 83 and 105 metres which explain the bore hole EM anomaly and may correlate with the upper sulphide intersections in holes NAD11-233 and 239. Assays are pending.
Exploration Target South of H Zone
Drill hole NAD08-171EXT was deepened by 74.5 meters from 212 to 286.5 meters in order to test for 'Sleeping Giant-type' mineralization south of H zone. In 2008, this hole intersected 0.63% Ni over 4.0m in mineralized peridotite occurring at the former end of hole. This mineralization did not extend from the point of hole deepening. However, the hole did intersect 2.85 metres of disseminated, net-textured and stringer sulphide from 259.40 to 262.25 metres which graded 1.57% nickel and 0.27% copper.
Preliminary bore hole electromagnetic (BHEM) survey results indicate that a weak in-hole anomaly detected at 260 meters is associated with this mineralization. The conductor associated with this anomaly is centered both down-dip and south of NAD08-171EXT and is interpreted to lie on the same plane as mineralization intersected in hole NAD08-119 (3.56% Ni & 0.61% Cu / 0.70 metres) at I Target located 300 metres up-dip to the east. The BHEM results also show a building off-hole anomaly beyond the end of hole NAD08-171EXT. This anomaly is interpreted to be caused by a moderate to strong conductor located both down-dip and south of the hole. Additional drilling will be required to more fully test these new targets.
