AMARC PROVIDES UPDATE ON DUKE COPPER-GOLD DISTRICT AND FILES PROJECT TECHNICAL REPORT

Amarc Resources Ltd. will file a National Instrument 43-101 technical report for the company's Duke project, British Columbia, today under Amarc's SEDAR profile. It will also be available on the company's website. The report provides details on the potential of the company's Duke porphyry copper deposit target discovery and its successful district-scale porphyry copper-gold targeting program, along with proposed exploration plans.

Amarc's 100-per-cent-owned Duke project is located 80 kilometres northeast of Smithers within the Babine district, one of B.C.'s most prolific porphyry copper-gold belts. The district, a 40 km by 100 km north-northwesterly striking mineralized belt, is host to Noranda Mines' past-producing Bell and Granisle copper-gold mines, and the advanced-stage Morrison copper-gold deposit. Amarc's Duke porphyry copper discovery is located 30 km north of the Bell mine. Extensive infrastructure exists in the district, which primarily relates to the forestry industry but also dates back to mining activity.

The porphyry copper system at Duke has seen only limited drilling. Many of the 30 historical shallow and closely spaced core holes intersected and ended in significant copper-molybdenum-silver-gold mineralization. In the main area of known mineralization, these holes extended to only a 124-metre vertical depth from surface. Examples of the results are:

  • Hole 71-14 intersected 87 m of 0.4 per cent Cu, 0.021 per cent Mo, 2.2 grams per tonne Ag and 0.05 g/t Au from 29 m to the end of the hole that includes 40 m of 0.48 per cent Cu, 0.023 per cent Mo, 2.6 g/t Ag and 0.07 g/t Au;
  • Hole 70-02 intersected 113 m of 0.3 per cent Cu, 0.012 per cent Mo, 1.1 g/t Ag and 0.06 g/t Au from 30 m that includes 12 m of 0.41 per cent Cu, 0.01 per cent Mo, 1.6 g/t Ag and 0.09 g/t Au.

The historical drilling was centred within a restricted part of a robust, three km north-south by one km east-west induced polarization chargeability anomaly, which is thought to have been offset by faulting. When reconstructed, this IP chargeability anomaly has a classic doughnut shape that was the target of Amarc's eight core holes completed in 2017 through 2018 (see Dec. 19, 2017, and June 12, 2018, news releases). Seven of the eight core holes drilled over an area measuring approximately 400 m north-south by 600 m east-west successfully intersected porphyry copper-style mineralization to a vertical depth of 360 m. This mineralization remains open to expansion. The report provides drill hole plans and results; selected intercept examples are:

  • 102 m of 0.22 per cent Cu, 0.014 per cent Mo, 1.3 g/t Ag and 0.06 g/t Au in hole DK17002;
  • 147 m of 0.27 per cent Cu, 0.028 per cent Mo, 1.1 g/t Ag and 0.05 g/t Au, including 20 m of 0.45 per cent Cu, 0.033 per cent Mo, two g/t Ag and 0.06 g/t Au in hole DK18005;
  • 58 m of 0.34 per cent Cu, 0.015 per cent Mo, 1.5 g/t Ag and 0.059 g/t Au included in a broader interval of mineralization in hole DK18006.

Notably, a single stepout hole (DK18004) completed by Amarc more than one km to the north of the seven other Amarc holes, and within the displaced portion of the IP chargeability anomaly, intersected substantial lengths of moderate- to low-grade copper and molybdenum mineralization, confirming a very extensive lateral dimension to the Duke porphyry copper system. Amarc is currently planning how best to undertake the drilling required to delineate the geometry and grade distribution of its Duke discovery in order to inform a mineral resource estimate and related studies.

Appreciating the copper-gold prospectivity of the Babine district and its relatively unexplored nature due to widespread glacial cover (four m to 18 m thick in the Amarc Duke discovery drill holes), Amarc has completed a comprehensive compilation of government and historical data over the entire 704 square km Duke project. This integrated study provided a new interpretation of the geological, geochemical and geophysical characteristics of the Babine district, identifying 12 previously unrecognized porphyry copper deposit targets with exciting potential. These target areas were defined, for example, by anomalous copper-gold-molybdenum-silver (and other porphyry indicator elements) till geochemistry, till samples with identified grains of bornite, chalcopyrite and/or biotite feldspar porphyry (BFP), compelling up-ice magnetic features, and indications of structural control along faults emanating from large deep-seated regional structures that likely controlled the emplacement of the prospective BFP intrusions, along with numerous other scientific vectors (please see the report for additional details).

Regionally, Amarc is planning for initial, focused ground surveys taking advantage of extensive logging-road networks across the property. These surveys would be followed by reverse circulation drilling, which would test prioritized targets for the presence of potential porphyry copper mineralized systems below cover, and, where a deposit target is confirmed, core drilling to determine the extent, grade and geometry of the mineralized system.

Quality control/quality assurance program

All drill core was logged, photographed and cut in half with a diamond saw. Half-core samples from Duke were sent to MS Analytical's Langley facility (17025 accredited) for preparation and analyses. Drill core samples were analyzed for Cu, Mo, Au, Ag and 35 additional elements by aqua regia digestion of a 0.5-gram sample followed by an inductively coupled plasma atomic emission spectroscopy/mass spectrometry finish. Au was also analyzed by fire assay fusion of a 30-gram sample followed by atomic absorption spectroscopy finish.

As part of a comprehensive QA/QC program, Amarc control samples were inserted in each analytical batch at the following rates: standards -- one in 20 regular samples, in-line replicates -- one in 20 regular samples and blanks -- one in 50 regular samples. The control sample results were then checked to ensure proper QA/QC.
