AuRico Metals Announces Results from Successful 2017 Drill Program Including 338m Grading 0.64 g/t Au and 0.45% Cu at Kemess East
TORONTO, Dec. 7, 2017 /CNW/ - AuRico Metals Inc. (TSX: AMI), ("AuRico" or the "Company") is pleased to report the full assay results from the Company's 2017 exploration program on the Kemess Property. Drilling this season focused on converting inferred resource blocks to indicated and testing the northern and southern limits of the Kemess East deposit (eight holes, 11,917 metres), which is located approximately one kilometer east of the Kemess Underground deposit and 6.5 kilometers north of the Kemess mill facility and other infrastructure. The 2017 exploration also tested the northern extension of mineralization within the Kemess Offset Zone ("KOZ") (two holes, 2,006 metres) located between Kemess Underground and Kemess East.
Highlights from this year's drilling at Kemess East include:
- KH-17-05 intersected 338 metres of 0.64 g/t Au and 0.45% Cu
- Including 120 metres of 1.05 g/t Au and 0.60% Cu
- KH-17-08B intersected 846.5 metres of 0.25 g/t Au and 0.28% Cu
- Including 208 metres of 0.37 g/t Au and 0.41% Cu
- KH-17-09 intersected 853.8 metres of 0.24 g/t Au and 0.25% Cu
- Including 147.5 metres of 0.40 g/t Au and 0.42% Cu
Highlights from this year's drilling in the Kemess Offset Zone include:
- KH-17-10 intersected 461.9 metres of 0.27 g/t Au and 0.22% Cu
- Including 75 metres of 0.61 g/t Au and 0.41% Cu
(The true thickness of the mineralized intervals is estimated at approximately 90% of the reported intercept length.)
(Refer to Table 1 for the Kemess East Drill Results, Table 2 for the KOZ Drill Results, Table 3 for Drill Collar Locations, Table 4 for the Kemess East Resource Estimate, and Figures 1-4 respectively for the Kemess East Plan Map, Kemess East Cross-Section, KOZ Plan Map, and KOZ Cross-Section.)
This year's exploration program had three key objectives: convert inferred resource blocks to indicated, expand the limits of the currently known deposit and test the northern extension of the known mineralization within the KOZ.
Commenting on today's exploration results, Chris Richter, President and CEO of AuRico Metals, stated; "We're pleased to report the outcome of this year's drilling on the Kemess property and believe we've successfully achieved our objectives. At Kemess East we expect to convert a significant amount of inferred resources to indicated resources and a number of the holes point to good potential to grow the resource to the south. At the Kemess Offset Zone, we intersected long intervals of gold and copper mineralization and this target remains open in every direction. The results from the Kemess East drill program will be incorporated into an updated Kemess East resource expected in the first quarter of 2018."
The current Kemess East resource estimate (see press release dated January 13, 2017 and Technical Report dated July 12, 2017) includes a high grade core estimated to contain Indicated Resources of 113.1 million tonnes grading 0.38% Cu and 0.46 g/t Au as well as Inferred Resources of 63.8 million tonnes grading 0.34% Cu and 0.31 g/t Au; as shown in Table 4). The high grade core of the Kemess East resource estimate is associated with strong potassic alteration and the overall resource is mostly hosted in the strong and moderate potassic alteration.
Although each hole in the 2017 program had multiple objectives they can generally be subdivided as follows: Holes KH-17-02, KH-17-04, KH-17-06, KH-17-08B and KH-17-09 were drilled in the southern Kemess East area. These holes targeted up to 175m south of the current indicated resource blocks within the inferred resource blocks. Drill holes KH-17-04, KH-17-08B and KH-17-09 bottomed in potassic strong alteration with good gold and copper mineralization that was previously modeled as lower grade. KH-17-04 was particularly intriguing as it bottomed in mineralization that was previously thought to be in barren intrusive rock.
Holes KH-17-03, KH-17-05 and KH-17-07 were drilled to test the northern area of the Kemess East deposit and to fill gaps in the current resource. KH-17-05 intersected mineralization as expected, successfully filling in a large gap in the drilling within the resource. KH-17-03 intersected the top of mineralization deeper than expected due to faulting. KH-17-07 deviated toward the area already tested by KH-17-03 and was therefore shut down prior to hitting mineralization.
Finally, holes KH-17-01 and KH-17-10 were designed to test the northern extension of mineralization within the KOZ. Both holes intersected significant mineralized intervals which extended the KOZ mineralization further to the north by 60m to 170m. KH-17-01 was shut down early due to drilling issues, however, we now have a better understanding of the mineralization, alteration and faulting within the KOZ and it remains open in all directions.
We expect that the 2017 drill program will contribute to converting inferred resource blocks to indicated resource blocks and increase the grade of the Kemess East resource. An updated resource for Kemess East is expected in Q1 2018. Following this year's drilling, the Kemess East Deposit remains open to the west towards the KOZ, to the north, and to the south.
Kemess Property Overview
The Kemess Property is located in north-central British Columbia, Canada, approximately 430 kilometres northwest of Prince George. The Kemess Underground Project is located approximately 6 kilometres north of the past producing Kemess South open pit mine that operated from 1998 to 2011 and produced 3 million ounces of gold and 749 million pounds of copper.
A Feasibility Study on the Kemess Underground Project was released on March 23, 2016 and proposes an underground panel caving operation with average annual production of 238,000 gold-equivalent ounces (129,000 ounces of gold and 52 million pounds of copper) for the first five years of a 12 year mine life.
A Preliminary Economic Assessment on Kemess East was released on May 29, 2017 and proposes another underground panel caving operation with average annual production of 222,000 gold-equivalent ounces (80,000 ounces of gold and 57 million pounds of copper) over a 12 year mine life.
Quality Control – Analyses and Sample Location
Exploration activities at Kemess are conducted by AuRico personnel under the supervision of Wade Barnes, Project Geologist and a Qualified Person as defined by National Instrument 43-101. Wade Barnes is a PGeo registered with the Association of Professional Engineers and Geoscientists of British Columbia (APEGBC) and he has verified the data and he has also reviewed and approved this news release.
Samples were prepared at an on-site sample preparation lab. The prepared 250g samples, crushed to 80% passing 10-mesh and pulverized to 85% passing 150-mesh, were shipped in security sealed pails to ALS Minerals in North Vancouver for analysis. The 2017 samples were analyzed for a suite of 48 elements, including iron, molybdenum, and silver, using 4-acid digestion with ICP mass spectrometry and ICP atomic emission spectroscopy finish on a 0.25 gram sub-sample. Significantly mineralized samples were additionally analyzed by an extra ore grade analysis for copper and molybdenum by ICP atomic emission spectroscopy, following a 4-acid digestion on a 0.5 gram sub-sample. Gold analyses were completed by standard 30g fire assay with an atomic absorption finish. The 2017 quality control ("QC") samples (blanks, duplicates, and certified reference materials) were inserted into the sample stream at regular intervals such that 2 in 25 (8%) of samples were submitted for QC purposes. QC sample performance was monitored on a regular basis, independently of the laboratories, and failures addressed in a timely manner. All sample batches were also subjected to each laboratory's internal QC procedures, for an additional 40% QC sample volume.
