AURICO METALS INTERSECTS 771.7M GRADING 0.465 G/T AU AND 0.365% CU AND ANNOUNCES RESULTS FROM 2015 DRILL PROGRAM AT KEMESS
AuRico Metals Inc. has released the assay results from its 2015 exploration program at the Kemess property. Drilling this season focused primarily on Kemess East (12 drill holes, 17,419 metres), located approximately one kilometre east of the Kemess Underground (KUG) deposit and 6.5 kilometres north of the Kemess mill facility. Three holes (4,365 metres) were drilled in what the company is calling the Kemess offset zone (KOZ), located between Kemess Underground and Kemess East (KE), and another nine holes (5,932 metres) were drilled elsewhere on the property.
Kemess East (KE)
The results from the first two drill holes at KE this year were released in an AuRico Metals press release dated Aug. 18, 2015. Highlights from the remainder of this year's KE drilling include:
- KH-15-23 intersected 458 metres of 0.64 gram per tonne gold and 0.437 per cent copper:
- Including 360.6 metres of 0.749 g/t Au and 0.478 per cent Cu;
- Including 167 metres of 1.022 g/t Au and 0.574 per cent Cu;
- KH-15-27 intersected 590 metres of 0.516 g/t Au and 0.366 per cent Cu:
- Including 475.8 metres of 0.615 g/t Au and 0.431 per cent Cu;
- Including 325 metres of 0.743 g/t Au and 0.492 per cent Cu;
- KH-15-30 intersected 771.7 metres of 0.465 g/t Au and 0.365 per cent Cu:
- Including 615.2 metres of 0.569 g/t Au and 0.429 per cent Cu;
- Including 224.4 metres of 0.773 g/t Au and 0.508 per cent Cu.
(The estimated true thickness of the mineralized intervals is 80 per cent of the reported intercept length.)

The inaugural Kemess East resource estimate containing 55.8 million indicated resource tonnes at 0.52 g/t gold and 0.41 per cent copper, with a further 117.1 million inferred tonnes at 0.38 g/t gold and 0.34 per cent copper, was released in an AuRico Gold (now Alamos Gold, an AuRico Metals predecessor company) press release dated Jan. 21, 2015, and in a technical report issued to AuRico Gold on Dec. 31, 2014, and reissued to AuRico Metals on July 2, 2015.
This summer's KE drilling has both increased the confidence in the inaugural KE resource and raised expectations for a potential increase in resources. Drilling has also identified a higher-grade core of mineralization estimated to be approximately 300 metres long. The KE deposit remains open to the east toward the Kemess East offset fault, to the south toward the postmineral sovereign intrusion and to the north where the Kemess East offset fault crosses the KE deposit.
"We're very pleased with results that came from our investment in drilling at Kemess over the summer," commented Chris Richter, president and chief executive officer of AuRico Metals. "We look forward to seeing what these results mean for an updated Kemess East resource, which we plan to release in the first quarter of 2016."
Kemess offset zone (KOZ)
The KOZ is directly east of the KUG deposit and is separated by a steeply dipping north-south fault, causing the KOZ to be shifted down elevation. The KOZ shows similar geological characteristics to KUG. Results from the Kemess offset drilling include:
- KH-15-06 intersected 297.7 metres of 0.347 g/t Au and 0.241 per cent;
- CuKH-15-12 intersected 467.25 metres of 0.222 g/t Au and 0.187 per cent Cu.
(The estimated true thickness of the mineralized intervals is 80 per cent of the reported intercept length.)
The KOZ is open to the east, to the south (toward the postmineral sovereign intrusion) and to the north (toward the Kemess North boundary fault and the Kemess North thrust fault, as seen with the KUG deposit). Drilling in the KOZ was designed to follow up on encouraging results from drill results from 2005 and 2013.
The nine holes drilled elsewhere on the property did not intersect any significant values. Geotechnical drill holes were also completed as part of the feasibility study update on Kemess Underground, in order to test the rock and overburden conditions around the triple decline location, the south tunnel location and the conveyor alignment corridor.
Kemess property overview
The Kemess property is located in north-central British Columbia, Canada, approximately 430 kilometres northwest of Prince George. Kemess Underground is located approximately 5.5 kilometres north of the past-producing Kemess South open-pit mine that operated from 1998 to 2011 and produced three million ounces of gold and 749 million pounds of copper.
A feasibility study on Kemess Underground was released on March 25, 2013, and proposes an underground panel caving operation with average annual production of 105,000 ounces of gold and 44 million pounds of copper over a 12-year mine life.
AuRico Metals is currently advancing a feasibility study update, which is expected to be released in the first quarter of 2016. Permitting is progressing as well and the company intends to submit its environmental assessment to provincial and federal regulatory bodies before the end of the first quarter of 2016.
Quality control -- analyses and sample location
Exploration activities at Kemess are being conducted by AuRico personnel under the supervision of Wade Barnes, PGeo, project geologist, a qualified person as defined by National Instrument 43-101. Mr. Barnes is registered with the Association of Professional Engineers and Geoscientists of British Columbia (APEGBC) and has verified the data and reviewed and approved this news release.
Samples were prepared at an on-site sample preparation lab. The prepared 250-gram samples, crushed to 80 per cent passing 10 mesh and pulverized to 85 per cent passing 150 mesh, were shipped in security-sealed pails to ALS Chemex Laboratory in North Vancouver for analysis. The 2015 samples were analyzed for a suite of 33 elements, including iron, molybdenum and silver, using four-acid digestion and ICP atomic emission spectroscopy on a one-gram subsample. Significantly mineralized samples were additionally analyzed by an extra ore grade analysis for copper and molybdenum by ICP atomic emission spectroscopy, following a four-acid digestion. Gold analyses were completed by standard 30-gram fire assay with an AA finish. The 2005 samples were analyzed for a suite of 35 elements, including iron, molybdenum and silver, using two-acid digestion and ICP atomic emission spectroscopy on a one-gram subsample prior, and the 2013 samples were analyzed for a suite of 33 elements using a four-acid digestion and ICP atomic emission spectroscopy. The 2005 and 2013 copper analyses were completed by AA spectrometry, following a three-acid digestion, and gold analyses were completed by standard 30-gram fire assay with an AA finish. Copper analyses were completed by AA spectrometry, following a three-acid digestion. Gold analyses were completed by standard one-assay-ton fire assay with an AA finish. The 2015 quality control samples (blanks, duplicates and certified reference materials) were inserted into the sample stream at regular intervals such that two in 25 (8 per cent) samples were submitted for quality control purposes. The 2005 and 2013 quality control samples (blanks, duplicates and certified reference materials) were inserted into the sample stream at regular intervals such that one in 25 (4 per cent) samples were submitted for quality control purposes. Quality control sample performance was monitored on a regular basis, independently of the laboratories, and failures were addressed in a timely manner. All sample batches were also subjected to each laboratory's internal quality control procedures, for an additional 40-per-cent quality control sample volume.
