Northern Gold Hits 209 Meters of 1.44 g/t Including 1 Meter of 97.88 g/t, 3 Meters of 19.85 g/t & 108 Meters of 2.33 g/t, Plus 2 Meters of 10.34 g/t, 9 Meters of 2.64 g/t & 29 Meters of 2.05 g/tadmin
Northern Gold Mining Inc. announced today assay results for six additional diamond drill holes totaling 1,358.6 meters of drill core in the Company’s ongoing 30,000 meter drill program at the Garrcon Deposit on the Garrison Gold Property. A total of 31 drill holes (6,726 meters) have been reported to date for the drill program that began May, 2010. Assay results for these latest six drill holes are listed in Table 1.
“These infill drill results both demonstrate the robust nature of this gold deposit and expand the known gold mineralization in new drill intercepts adjacent to and between holes drilled during previous programs within the resource footprint,” said Martin Shefsky, President and CEO of Northern Gold Mining Inc. “We will continue our aggressive drill program utilizing two drills and focusing on systematic infill, definition and step out drilling. Results of drill holes completed prior to December, 2010 will be used in the updated NI 43-101 resource calculation expected to be completed in the first quarter of 2011.”
All the holes shown in Table 1, except GAR-10-37, are infill and expansion holes within the existing resource footprint and were drilled from Section Line 12+50W to Section Line 13+00W. These infill holes continue to encounter long downhole intercepts of stockwork mineralization at and above the resource cutoff grade. Mineralization intercepted in GAR-10-42 is excellent grade and includes a one meter assay of 97.88 g/t. This is the second assay in 7,269 assays that has assayed higher than 34 g/t. Statistically, it is not significant, but for informational purposes, the resultant assays are shown when the grade is cut to 34 g/t.
GAR-10-37 – collared on Section Line 11+50W at about8+40N on an azimuth of 342 degrees true and an inclination of -44 degrees is drilled across both the Shaft and North Zones. The hole parallels GAR-10-36 collared approximately 35 meters to the north and CO6-07 collared approximately 95 meters to the south. Both Shaft Zone and North Zone mineralization in the hole is significantly lower than similar zones in either of the parallel holes. Shaft Zone mineralization is similar to that encountered in GAR-10-11, which is located about 25 meters to the west.
GAR-10-38 – collared on Section Line 12+50W at about 9+50N on an azimuth of 155 degrees true and an inclination of -63 degrees is drilled on the south margin of the Deposit testing the Shaft Zone. Mineralization in GAR10-38 is lower grade than that seen in GAR-09-03A which is collared about 25 meters to the north and may indicate that there is little room for expansion of the resource south of GAR-10-38.
GAR-10-39 – collared on Section Line 12+75W at about 9+13N on an azimuth of 346 degrees true and an inclination of -43 degrees crosses both the Shaft and North Zones. The hole parallels C06-06 collared about 40 meters to the north and sub-parallels C07-03 collared about 40 meters to the south. In crossing the Shaft Zone, GAR-10-39 is better grade than C06-06 and consistent with the grade in C07-03. In the North Zone, GAR-10-39 is better grade than both C06-06 and C07-03. Because the last meter in the hole returned an assay of 2.79 g/t the hole was deepened another 60 meters and terminated in the north ultramafics. Assays for the deeping are pending.
GAR-10-40 – collared on Section Line 12+75 at about 10+35N on an azimuth of 343 degrees true and an inclination of -45 degrees is north of the Shaft Zone and crosses the North Zone. The hole parallels C06-06 collared about 90 meters to the south and GAR-10-24 drilled about 70 meters to the north. GAR-10-40 is better grade than both GAR-10-24 to the north and C06-06 to the south.
GAR-10-41 – collared on Section Line 12+50W at about 10+55N on an azimuth of 160 degrees true and an inclination of -63 degrees is crossing a bit of the North Zone but is drilled through the central portion of the Deposit at a steeper angle than the surrounding holes. Mineralization encountered above 118 meters is low grade and consistent with nearby hole GAR09-08. Below 118 meters, the mineralization encountered improves. Assays are pending on the only drill hole within 100 meters.
GAR-10-42 – collared on Section Line 13+00W at about 10+65N on an azimuth of 160 degrees true and an inclination of -45 degrees is drilled entirely within the Shaft Zone. The hole parallels GAR-09-05 and crosses GD86-16 and GAR-56. Mineralization intercepted in GAR-10-42 is consistent with GD86-16 and better than the mineralization in both GAR-56 and GAR-09-05.
Quality Assurance/Quality Control
Northern Gold Mining Inc. has implemented a QA/QC protocol for its exploration work. Northern is currently diamond drilling the Garrison Gold Property and the drilling contractor is Major Drilling Group International Inc. Core size is NQ, to give good sample sizes and enabling the possibility for at least two step-downs if ground conditions should require it. Core is delivered to the secure Core Shack facility by the driller or picked up by one of Northern Gold’s designated personnel and transported to the Core Shack facility. In addition to recovery and RQD (Rock Quality Designation) data geologic parameters including lithology, alteration, quartz veining, presence and identification of sulfide mineralization along with other geologic parameters are noted and recorded. Core is marked in one meter intervals for splitting, sampling and assaying, unless geologic data indicate a shorter sample interval. Prior to splitting, all core is photographed. Core splitting is done with a diamond core saw and 1/2 of the drill core is submitted to Expert Laboratories, an accredited laboratory (PTP-MAL – Accredited by Standards Council of Canada – In full accord with ISO/IEC Guide 43-1 “Proficiency Testing by Interlaboratory Comparison”) in Rouyn-Noranda, Quebec for assaying. The remainder of the core is stored at the Garrison Gold Property. All sample intervals where visible gold is observed to be present are automatically submitted for analysis using the metallic screen procedure where the entire half core is crushed, pulped and screened at 100 mesh. The screen oversize is assayed in total and the screen undersize is fire assayed in triplicate using a gravimetric finish.
All other samples are analyzed by conventional fire assay using a 30 gram sample with geochemical finish. All samples that assay greater than one gram are re-assayed with conventional fire assay using a gravimetric finish. Conventional fire assay sample prep consists of crushing to 90% passing 10 mesh from which a 300 gram sample is split and pulped to 90% passing 200 mesh and from which a 30 gram sample is taken for fire assaying. Following completion of fire assaying at Expert Laboratories, pulp samples are forwarded by Expert to SGS’ certified laboratory (ISO/IEC 17025), in Toronto, Ontario for CN solubility assaying and for multi-element analyses of select samples. CN solubility test uses a 1% CN solution added to 30 grams of sample and shaken for an hour prior to settling and decanting for geochemical analysis. Multi-element analysis is conducted using 4-acid digestion followed by ICP analysis with OES finish (Inductively coupled plasma optical emission spectroscopy). Northern inserts a mixture of gold standard samples, blank samples and duplicate samples into the sample stream at a rate approximating 10% of total original samples. Samples are normally transported in a Company truck from the Property to Expert Labs in Rouyn-Noranda. Chain of Custody protocols require the signing and maintenance of logs and receipts each time the samples are picked up from or delivered to a new location. When utilizing commercial transportation, all shipping sacks are sealed with a numbered tag, the removal of which is recorded upon receipt by Expert Laboratories. Check analyses are conducted on a regular basis utilizing SGS’ laboratory, in Toronto, Ontario.
