gUMMARY

Northern Dynasty Explorations Ltd., as operator for the Ontario Gold Joint Venture, holds the McGruer Lake Property (18 claims) north of Eyapann'kama Lake in northwestern Ontario. These claims cover significant arsenopyrite-gold mineralization associated with an iron formation horizon in a 120 m wide ductile shear zone. This report discusses the results of the 1985/86 field programs which included geological mapping and electromagnetic (EM-16) surveying.

Program Results: 1. The previously discovered gold showingwas further exposed and sampled.

2. No new showings were found.

1.1 Introduction

The McGruer Lake Property comprises a total of 18 claims held by Northern Dynasty Explorations Ltd. in trust for the Ontario Gold Joint Venture, north of Eyapamikama Lake in northwestern Ontario.

These claims lie in the same "greenstone" belt and cover similar host lithologies as the Opapimiskan Lake Gold Deposit (reported reserves: 6 million tonnes grading 7.0 g/tonne gold) located 48 km to the southeast which is being developed through a consortium headed by Placer-Dome Inc.

1.2 Locat i on and Access

The McGruer Lake Property is located 170 km north of Pickle Lake, northwestern Ontario (Figure 1).

Access to the area in the summer months is by float plane from Pickle Lake or Windigo, 55 km southwest of the claims at the terminus of Highway 599. Winter access is by ski-equipped float plane from Pickle Lake or via the Weagamow Indian Reserve winter road and a connecting system of lakes. A snowmobile trail has been cut from Eyapamikama Lake into the property along grid l i.ne 5 + OOE.

1 . 3 Claim Status .and J i ties

The McGruer Lake Property comprises a total of 18 claims (Table 1) held by Northern Dynasty Explorations Ltd. in trust for the Ontario Gold Joint Venture (Northern Dynasty Explorations Ltd., Newfields Minerals Inc., Westfield Minerals Limited and Dunlop Explorations). The addresses of the property holders are listed in Appendix 1. The claims are located in the Sioux Lookout District of the Patricia Mining Division of Ontario.

1.4 Personnel and Syryey Dates

The field work recorded in this report was completed in several phases between July 17 and September 9, 1985. See Appendix 2 for personnel involved and survey dates.

1962 Emslie (1962) carried out ODM reconnaissancemapping (scale 1" - 4 mi.).

1959 A small drill program was carried out west ofMcGruer Lake by the Anaconda Company (Canada) Ltd. No assessment reports are available. A general lack of outcrop in the area suggests the target was an airborne EM conducted related to massive sulphide exploration.

1971 Thurston et al. (1971) carried out ODM recon naissance mapping (scale 1" s 4 mi.).

1981 Andrews et al. (1981) conducted a preliminaryevaluation of the geology and economic potential of the area for the Ontario Geological Survey.

1984 A large Ontario Geological Survey (OGS) crewmapped the area from Agutua Arm to the eastern end of Eyapamikama Lake. Results of their work were released as Bartlett et al. (1984) and Breaks et al. (1984).

2.O Geolpgleal_Report

2 . 1 Introduction

Geological mapping covered most of the property and is plotted on Plate 1.

2.2 Phys i og r a phy

The area bordering Eyapamikama Lake is characterized by low lying areas of muskeg and boulder till with few outcrops. Further to the north on the cut grid, bedrock exposure is very good over large areas and is about 20^ overall.

Drainage is poor throughout the property resulting in common areas of muskeg. Clay deposits were not observed. Glacial striations on the property and throughout the greenstone belt are consistently oriented at about 225" Az.

2.3 Regipnal Geology

The North Caribou Greenstone Belt forms part of the Archean Sachigo Sub-province of the Superior Province of the Canadian Shield. The Eyapamikame Lake portion of the belt is 40 km long, 10 km wide and is folded into a large east-west syncline (Breaks et al ., 1984). It is bounded to the north by migmatites, mainly sedimentary in origin, and. to the south and west by felsic intrusives (Fig. 3).

The McGruer Lake Property lies on the north limb of the Eyapamikama syncline and covers gold-bearing iron formations along the volcanic-sediment contact and a coincident major ductile shear zone. Metamorphism along this horizon is probably of lower amphibolite grade.

2.4 Local Geo]l pgy

2-4.1 Qut:line of Lithplpgies

The succession of lithologies found on the property is summarized in Table 2 and their distribution plotted on the geology map (Plate 1).

2.4.2 Sjtruct ujra

The dominant structural feature on the property and across the entire North Rim of the greenstone belt is a wide ductile shear zone coincident with the Active Zone (Table 2). This shear zone is typically 120 m wide on the property but ranges up to one kilometre in width toward the western end of the greenstone belt. At least three phases of deformation can be discerned within the Active Zone

and are marked by subvertical, 5 0" east-plunging, and subhorizontal east-west "Hneations and small isoclinal fold axes. The latter two deformations are also present in the less deformed turbidite unit to the south. The lensoidal character of the lithologies on all scales is a reflection of a multiple shearing and folding history.

The iron formations which locally host gold mineralization form large internally deformed enclaves in the more highly deformed, less competent lithologies of the Active Zone.

2.4.3 M i ne r a JIJzat .ion

Massive to disseminated gold-bearing arsenopyrite mineralization occurs in siliceous iron formation (metachert) and adjacent sedimentary rocks centred at 11+OOE, 0+50N. A chip sample across a true width of 1.7 m assayed 5.1 g/tonne gold. This zone has been traced for 35 m along strike.

The factors controlling the arsenopyrite mineralization are not well understood. At the main showing (Plate 1), arsenopyrite occurs in three ways: 1. replacing magnetite in magnetite-banded iron formation; 2. a s selvages and envelopes on common quartz-tourmaline veins in the mineralized zones, and 3. in shear zones up to 20 cm wide which parallel the regional east-west foliation.

3.0 Electroma( ; EM-1 6) Report

A ground electromagnetic (EM-16) survey was run over most of the McGruer Lake grid in 1985 (Plate 2). For comparisons with magnetic and soil geochemical anomalies run on the property see Gorzynski et al. (1985 - Plates 13 and 14).

Anomaly GE-1

Location 1+OOE/0+65N to 3+OOE/0+50N

This very strong anomaly is coincident with a large and strong magnetic high (anomaly GM-1), and may be continuous with the coincident electromagnetic-magnetic anomalies GE-3 and GM-3 across the west bay of McGruer Lake. A lone outcrop on the anomaly indicates it is due to a magnetite iron formation.

Anomaly GE-2

Location 1+OOE/0+65S to 6+OOE/0+60S

This set of three moderately strong anomalies is largely coincident with magnetic anomaly GM-2. These anomalies are at least partially due to magnetite iron formation exposed in outcrop (Plate 1).

Anomaly 6E-3


This strong anomaly is coincident with magnetic anomaly GM-3. Its cause is probably a magnetite iron formation locally observed along its trend.

Anomaly GE-4


This strong anomaly is coincident with magnetic anomaly GM-6 andpartially coincident with As-Au soil anomaly GC-2. It occurs in themafic volcanic unit. Its cause is not known.

GE-5


This strong anomaly is coincident with magnetic anomaly GM-5 which continues further west for 400 m. It outlines the trend of the arsenopyrite-bearing magnetite and/or pyrrhotite iron formation which hosts the main zone of gold mineralization at 11+OOE/0+50N.

-11-

AngiTialy 6E-6


This weak but persistent anomaly occurs near the mafic volcanic- Active Zone contact. It has no coincident magnetic anomaly. Its cause has yet to be investigated.

GE-7

Location 17+OOE/1+OOS to 24+OOE/0+10N

This moderately strong electromagnetic anomaly trends across severalsmall magnetic anomalies. It occurs in the turbidite unit south ofthe Active Zone. Its cause is not known.

A number of other weaker and/or less persistent electromagnetic anomalies occur on the grid. They have not been investigated.
