The Newton (Scum Lake) occurrence is located on a small hill, east of the Taseko River and approximately 2.5 kilometres northwest of Scum Lake.

Regionally, the area occurs within the Intermontane Belt, close to the eastern margin of the Jurassic to Paleogene Coast Plutonic Complex. Intrusive rocks underlying the property are probably related to this complex.

Locally, the area is underlain by volcanic rocks of the Upper Cretaceous Kingsvale Group (or its equivalent), comprising a succession of andesitic tuffs that have been intruded by Eocene granodiorite, diorite and quartz diorite.

Mineralization consists of chalcopyrite with minor amounts of molybdenite, chalcocite and up to 10 per cent pyrite occurring as disseminations and in quartz veinlets within altered sedimentary rocks, silicified porphyritic andesite, andesitic volcanics and the porphyritic granodiorite (quartz feldspar porphyry, feldspar porphyry and biotite feldspar porphyry). Minor sphalerite and galena are also reported in quartz veins.

Alteration envelopes associated with the quartz veinlets consist of sericite, clay, hematite and silica whereas minor amounts of calcite and chlorite occur along fractures. Accessory magnetite occurs as disseminations in the porphyry. The porphyry contains an oxidized (leached) zone, approximately 30 metres thick, followed by a zone of supergene enrichment, up to 60 metres thick, overlying the primary mineralization. Diamond drilling has been performed over an area of approximately 480 by 1200 metres.

In 1965, Amax completed a reconnaissance soil sampling program on the area. In 1971, Duval completed a magnetometer survey. During 1971 through 1973, Cyprus Exploration Corporation completed an induced polarization survey, geological mapping and 10 diamond drill holes, totalling 1695 metres, on the area as the J and K claims. Diamond drilling yielded intercepts of 0.16 per cent copper over 2.4 metres in hole 72-1, 0.20 per cent copper over 12 metres in hole 72-3, 0.16 per cent copper over 3 metres in hole 72-4, 0.13 per cent copper over 6 metres in hole 72-5 and 0.35 per cent copper over 3.9 metres in hole 72-8 (Property File - Cyprus Exploration Corporation [1973-04-01]: Exploration and Diamond Drill Program 1972).

In 1979, Kerr Addison Mines examined the property. In 1982, Taseko Mines completed a program of diamond drilling on the area as the Skum Lake property. The best drilling intersection, 2.8 grams per tonne gold, 13.1 grams per tonne silver and 0.49 per cent copper over 3.05 metres, was obtained from within altered volcanic (sedimentary?) rocks between intervals of porphyritic granodiorite (Assessment Report 11001). Other drill intercepts included 0.51 gram per tonne gold over 19.8 metres in hole 82-4 and 0.79 gram per tonne gold over 13.5 metres in hole 82-1 (Property File - Verdstone Gold Corp. [1991-10-15]: No. 198 (1991) - Newton Hill Exploration Funding Secured).

In 1990, Verstone Gold optioned the property and completed a program of geochemical sampling and trenching. Samples from the trenches yielded up to 0.10 per cent copper over 75 metres in trench 90-02, whereas another trench (90-06), located 600 metres to the southeast, yielded 0.62 gram per tonne gold over 54 metres (Property File - Verstone Gold Corp. [1991-07-18]: No. 138 (1991) - Newton Hill Claims Optioned).

In 1991, surface trenching yielded up to 1.06 grams per tonne gold over 7.8 metres in trench 91-14, 0.86 gram per tonne gold over 47.4 metres in trench 91-20 and 0.10 per cent copper over 76.8 metres in trench 91-13 (Property File - Verdstone Gold Corp. [1991-12-09]: No. 236 (1991) - Newton 50/50 joint venture project).

In 1992, Verdstone Resources completed five diamond drill holes. Highlights of diamond drilling included 0.11 per cent copper with 0.17 gram per tonne gold over 178.2 metres in hole 92-01, including 0.28 per cent copper with 0.23 gram per tonne gold over 22 metres; 0.04 per cent copper with 0.41 gram per tonne gold over 120 metres in hole 92-04, including 0.17 per cent copper with 0.35 gram per tonne gold over 20 metres, and 0.02 per cent copper with 0.75 gram per tonne gold over 48 metres; 0.12 per cent copper with 0.24 gram per tonne gold over 13.8 metres and 0.05 per cent copper with 0.58 gram per tonne gold over 24.3 metres in hole 92-05 (Property File - Verdstone Resources [1992-04-27]: 5-hole program at Newton Hill; A. Schmidt [2002-12-01]: Compilation Map - Newton Hill Prospect). The property was dropped later that year.

In 1996, Verdstone Resources re-optioned property and planned a program of diamond drilling on an untested magnetic high.

In 2006, High Ridge Resources conducted a diamond drill program with the most significant result from DH06-12 averaging 2.3 grams per tonne over 49 metres (Assessment Report 29088). The 2006 drilling identified chalcopyrite, bornite, corellite, chalcocite, malachite and azurite in fine-grained, disseminated crystals and to a lesser extent within veins and on fractures. Secondary minerals included sericite/muscovite, kaolinite, hematite, magnetite, barite and ankerite.

In 2009, Amarc Resources Ltd. acquired an 80 per cent interest in the Newton property from High Ridge Resources and conducted a 14-hole drill program in the fall of 2009. Assays returned broad, continuous intervals of bulk-tonnage–style gold, silver, copper and zinc. Highlights included drillhole 9004, which returned 189 metres grading 1.56 grams per tonne gold and 7.9 grams per tonne silver (Assessment Report 31636).

In 2010, Amarc Resources Ltd. conducted an induced polarization ground geophysical survey defining an anomaly approximately 450 metres south of the 2009 drilling. Amarc Resources Ltd. then completed a drill program on the Newton property. Highlights of this program include drillhole 10020, which returned 138 metres grading 0.46 gram per tonne gold and 4.1 grams per tonne silver (Assessment Report 32965).

In 2011, Amarc Resources Ltd. completed more drilling on the Newton property, producing encouraging results. Highlights include drillhole 11045, which returned 161.7 metres grading 1.05 grams per tonne gold and 3.6 grams per tonne silver (Press Release, Amarc Resources Ltd., December 6, 2011).

In 2012, Amarc Resources Ltd. announced an inferred resource estimate of 111.5 million tonnes grading 0.44 gram per tonne gold and 2.1 grams per tonne silver, calculated at a cut off of 0.25 gram per tonne gold (Press Release, Amarc Resources Ltd., September 26, 2012). Amarc Resources Ltd. also completed a drill program in 2012. Highlights include drillhole 12060, which returned 321 metres grading 0.55 gram per tonne gold and 3 grams per tonne silver (Press Release, Amarc Resources Ltd., April 11, 2012).
