VANCOUVER, Dec. 19, 2017 /CNW/ - Amarc Resources Ltd. ("Amarc" or the "Company") (TSX-V: AHR; OTCBB: AXREF) is pleased to provide results of its 2017 exploration programs, which focused on advancing development of a new generation of British Columbia ("BC") porphyry copper mines. Each of its 100% owned IKE, DUKE and JOY projects located in southern, central and northern BC, respectively, have proximity to industrial infrastructure, power, rail and roadways. This year, Amarc completed a $3.3 million surface exploration and drill program at IKE, a $400,000 drill program at DUKE and a $1.9 million surface exploration and drill program at JOY. Amarc believes these projects rank among BC's most important new mineral developments. Please see the updated corporate presentation available on Amarc's website at www.amarcresources.com.
Work at the IKE property has now delineated a copper-molybdenum-silver mineralized system measuring at least 3.5 km by 2 km through combined induced polarization ("IP") surveys, talus geochemical sampling and the earlier drilling of 21 core holes at the IKE deposit. The sulphide mineralized IKE system has the geological earmarks of important copper-molybdenum-silver mines like Morenci and Sierrita in Arizona, and Valley in BC. In addition, at least five significant porphyry copper deposits targets have been established within 10 km of the IKE discovery.
At DUKE, results received from two recently completed drill holes, both of which drilled lengths of over 500 m, indicate the discovery of an important new porphyry copper-molybdenum-silver-gold deposit. Both holes successfully targeted porphyry copper mineralization to depth and significantly below mineralization intercepted by historical drill holes that, on average, were drilled to depths of only 90 m. Importantly, after intersecting some 400 m of copper-molybdenum porphyry mineralization, continuation of the most westerly of the two drill holes encountered adjacent bulk tonnage-style gold-copper mineralization that is open to expansion. With the previously producing Bell and Granisle porphyry gold-copper mines nearby, this unexpected and exciting new development multiplies both the potential of the DUKE project, and the regional porphyry district staked by Amarc.
At JOY, with the new acquisition of the expansive PINE claims, the Company now controls the northern extension to the prolific Kemess gold-copper district. Centerra Gold recently announced the $310 million acquisition of AuRico Metals, owner of the Kemess District. Amarc has identified a new, 20 km long northeast trending structural corridor that hosts over 10 compelling porphyry gold-copper deposit targets. These focused targets are the result of extensive historical surface surveys and drilling.
Amarc and HudBay Minerals Inc. ("Hudbay") (TSX:HBM; NYSE:HBM) continue to assess the 2017 data from IKE and JOY and consider plans for 2018. Hudbay is expected to provide notice of its commitment to 2018 exploration programs by year-end.
IKE PROJECT
The 462 km2 IKE Project claims are located 33 km northwest of the historical mining community of Gold Bridge, BC. From 2014 to 2016, Amarc discovered the IKE deposit by drilling more than 12,000 m in 21 widely-spaced core holes intersecting copper, molybdenum and silver mineralization over a large volume of host rock. This drilling indicates the potential for extensive resource volumes, which remain open to expansion in all lateral directions and to depth. In addition, during this period, extensive regional geophysical, geochemical and
geological surveys identified a number of porphyry copper deposit targets proximal to IKE. Age dating of porphyry mineralization discovered within the IKE district has confirmed at least four separate porphyry mineralizing events, which occurred over an exceptionally long period of 46 million years. These porphyry copper mineralized systems become progressively more gold-bearing moving northward from the IKE deposit (see news release dated October 17, 2016).
In 2017, after review by the BC Government and First Nations, Amarc received a five-year, area-based permit for the IKE Project exploration activities, which includes authorization for 300 drill holes and 250 line-km of IP surveying, and provides regulatory certainty and operational flexibility at site. As announced earlier this year, the Company has partnered with Hudbay to fund advancement of the IKE Project (see Amarc News Release dated July 6, 2017) with Amarc as operator.
This year the partners focused on exploration of a number of the regional porphyry copper deposit targets located within 10 km of the IKE deposit. Field programs included 20 km2 of detailed geological mapping, collection of 616 talus fines geochemical samples, completion of 82 line-km of IP surveys and exploration drilling of nine core holes totalling 2,796 m in three targets.
One hole was drilled at the Rowbottom porphyry copper deposit target located 4.5 km northwest of the IKE deposit. This hole intersected significant intervals of porphyry copper-molybdenum mineralization hosting elevated silver and gold values, which are cut by a number of post mineral dykes. This hole was drilled into an IP anomaly measuring 1.3 km by 1.0 km that remains open for further surveying. Additional drilling is required both laterally and to depth in order to determine the geometry and grade distribution of the Rowbottom deposit. Assay results from hole RB17001 are tabulated below.

Eight, very wide-spaced wild-cat exploration holes in the IKE district were also completed at the Mad Major and OMG targets, a 32 km2 area which hosts pronounced anomalous copper, molybdenum and tungsten surface geochemical anomalies combined with extensive IP chargeability results. One hole (MM17005) in this extensive target returned copper and molybdenum values within an intrusive dyke-like body, as reported below. Further work is required to determine if a large, nearby, mineralized intrusive body could be the source of the well-mineralized dyke intersection.

Importantly, IP geophysical work undertaken in 2017 showed the IKE mineralized system is much larger than originally thought and is now known to extend for at least 3.5 km east-west by 2 km north-south, as outlined by IP chargeability surveys and talus fines geochemical sampling. Central to this large sulphide-mineralized system are the 21 discovery core holes drilled by Amarc in 2014 through 2016 over an area measuring 1.2 km by 1.0 km and 875 m vertically. All of these holes intersected long intervals of copper (chalcopyrite) and molybdenum (molybdenite) mineralization. Selected highlights from previously reported results from these drill holes are presented below for ease of reference.

The mineral grades of resources and reserves of important porphyry copper producers and projects located in central BC typically range from 0.30% - 0.54% copper equivalent ("CuEQ"). Amarc believes that results from its IKE deposit programs are indicating numerous geological similarities to some of the world's important copper molybdenum-silver deposits, like Sierrita, Morenci and Valley. Planning for 2018 is underway. It is expected that the Company's exploration focus at IKE next year will be wide-spaced drilling throughout the 3.5 km by 2 km mineralized system in order to delineate the deposit's overall geometry and copper-molybdenum-silver grade distribution.
DUKE PROJECT
Amarc's DUKE deposit target and the adjacent 190 km2 porphyry copper district is located 80 km northeast of Smithers, BC and 30 km north of former mines (Bell and Granisle) operated by Noranda Mines.
In 1971, prior operators drilled the DUKE porphyry copper target with 29 shallow diamond drill holes (only 90 m deep on average). This historical drilling demonstrated the presence of near surface, copper-molybdenum-silver-gold mineralization over an area measuring approximately 800 m by 400 m, that is open to extension laterally and to depth. The surrounding DUKE district, now covered by Amarc mineral claims, also hosts multiple additional porphyry copper exploration targets for future assessment.
Following review by the BC Government and First Nations the Company received two five-year, area-based permits for DUKE Project exploration activities, including 200 km of IP surveying and 20 drill holes.
In November 2017, Amarc funded two core holes that targeted the Duke deposit. DK17001 drilled at -59o for 518.5 m and DK 17002, located 200 m to the southeast of DK17001, drilled at -45o for 527 m were designed as an initial test for porphyry mineralization below the historical, unusually shallow drill holes. The two, 2017 core holes intersected mainly biotite-feldspar-porphyry and felsic intrusive rock – rock types that also host the Bell, Morrison and Granisle porphyry copper deposits in the region. Assay results from Amarc's 2017 drilling at DUKE are tabulated below. These successful results indicate that Amarc has discovered another important porphyry copper-molybdenum-silver-gold deposit, which hosts CuEQ grades comparable to those mined elsewhere in BC.
In addition and importantly, indications are that DK17001 drilled through a copper-molybdenum-silver porphyry deposit and into a potential gold-copper porphyry-type deposit located adjacent to DUKE as evidenced by assay results from 425 m to the end of that hole. This gold-bearing interval hosts a very different geochemical expression than the rocks above which assay for copper, molybdenum and silver; its importance was not specifically recognized during drilling. The last 9.5 m of hole DK17001 returned excellent assays for bulk tonnage gold-copper deposits as highlighted in a separate table below, indicating hole DK17001 was stopped prematurely. Moreover, the host rock to the gold-copper mineralization intercepted in DK17001 also appears to be logged near surface in a shallow (55 m) historical hole drilled about 200 m to the north but that historical interval was not assayed.

The Company is developing plans to initiate a grid-type drill program as early as Q1 2018, in order to commence delineation of the geometry and grade distribution in relation to the both the bulk tonnage gold-copper mineralization and copper-molybdenum-silver mineralization in the DUKE discovery area.
JOY PROJECT
Amarc's JOY Project lies 310 km north of Mackenzie in a region of BC considered to have high potential for the discovery of important scale, porphyry gold-copper deposits. The JOY claims are located 20 km north of the prolific Kemess District, host to the former Kemess South Mine and AuRico Metals' government-approved Kemess Underground Project. Recently, Centerra Gold agreed to purchase AuRico Metals for $310 Million.
Past operators conducted prospecting-style work indicating a number of substantial porphyry gold-copper deposit targets across the JOY claims. Following review by the BC Government and First Nations, the Company received two-year, area-based permits for JOY Project exploration activities, including 100 line-km of IP surveying and 20 drill holes. Amarc has partnered with Hudbay to fund the advancement of the JOY property (see Amarc News Release dated August 22, 2017) with Amarc as operator. The 2017 programs at JOY included 50 km² of geological mapping, collection of 638 surface geochemical samples, completion of 49 line-km of ground IP and 470 line-km of airborne geophysical surveys along with drilling of 1,527 m in three core holes. This drilling tested a coincident IP geophysical and geochemical target on the JOY claims.
The three exploration holes returned strongly anomalous results in gold and zinc over significant intervals, hosted mainly within highly altered quartz monzonite intrusive and volcanic rocks. These results are comparable to those from two historical holes drilled by a previous operator some 2 km to the east on the adjoining PINE claims. Taken together these long intervals of highly altered and anomalous core may represent a classic rock alteration style typically found flanking porphyry copper-gold deposits. Notably, multiple magnetic, geochemical and IP deposit-scale targets occur in a prominent, 20 km long, northeast trending structural belt located 1.5 km south of Amarc's 2017 drilling. Amarc has identified this compelling target trend as the Finlay Magnetic Corridor, which also hosts the historical Pine porphyry gold-copper deposit (see new corporate presentation at www.amarcresources.com).
As work progressed this year, Amarc recognized the high potential for major gold-copper deposit discoveries along the Finlay Magnetic Corridor, leading the Company to conclude option agreements with Gold Fields Toodoggone Exploration Corporation and CascadEro Copper Corp. in order that a 100% interest in the 3232 km PINE property could be purchased (see Amarc news release August 29, 2017). The PINE property covers the favorable Finlay Magmatic Corridor, and lies between Amarc's JOY claims and AuRico's Kemess developments.
Amarc considers the JOY and adjacent PINE mineral claims (now collectively known as the JOY Project) to be significantly underexplored and to represent the northern extension of the Kemess gold-copper district. Highly favorable geology, surface geochemical sampling and geophysical surveys, along with drilling in 136 holes by past operators, has resulted in narrowing the exploration focus to a number of important-scale, gold-copper deposit targets.
Extensive field work is being planned for 2018 on the JOY Project. Applications to the provincial government for exploration permits on the newly acquired PINE portion of the project area will advance after community consultation this winter.
Plans being developed for 2018 include systematic IP surveys over the more than 10 deposit-scale targets already identified within and adjacent to the Finlay Magnetic Corridor. Drilling is expected to follow to test the sulphide systems delineated by the IP surveys for major gold-copper deposits.
