1 ip- S2A05SWM LYBSTER 010 OEOLOOICAL REPORT ON J.W. REDDEN PROPERTY LYBSTER TOWNSHIP THUNDER BAY MINING DIVISION June 20, 1979 Report submitted by ikw. Redden, B.Sc.(Oeol)

2 INTRODUCTION The J.W. Redden Property consists of four mining claims in the Lybster Twp. Mining claim TB U6UUl6 covering the east half of lot R118 was recorded in August 1977 while TB U65725 covering the west half of lot R118 and TB U65723 and TB U6572U covering the east and west halves of lot Rlk5 were recorded in June The claims are considered a silver prospect. The property is held by J.W. Redden, 317 Viking Cres., Labrador City, Newfoundland, A2V 1R6. This survey was carried out between May 15 and June 20, LOCATION AND MEANS OF ACCESS The property is located in the southwest part of Lybster Twp on the north flank of Silver Mountain. This area is a- bout 60km WSW of Thunder Bay, Ontario. Access to the property is via a bulldozer track which crosses the southern part of the claim group. The bulldozer track branches to the north from an old road which intersects Hwy 593 about 1.8km south of the junction of Hwy 588 and Hwy 593* The bulldozer track can also be reached via a private road which intersects Hwy km south of the junction of Hwy 588 and Hwy

3 2. These routes are shown on figure 1. HISTORY OF PREVIOUS WORK The first recorded work on the property covered by the survey was in 1977 on TB U6bljl6. This work consists of bull dozer stripping near line 6E at 0+70N. Older workings, consisting of a trench and adit are also present. From their appearance and the size of trees growing on the dump, the work was done in the i860 1 s. Extensive lit erature searches fail to reveal any references to this work. Work conducted on the property during 1979 includes linecutting, geological mapping, leveling, geochemical samp ling, and bulldozer trenching. * DESCRIPTION OF ROCK TYPES Introduction An extensive literature is available on the geology of the Proterozoic rocks of the Thunder Bay area. This report will only highlight the salient features of the various units. More extensive descriptions may be found in the bibliography. Iron Formation (Gunflint Fm.) No outcrops of the iron formation exists on the claim i* group. Based on the thickness of the various formations on ad jacent properties, the iron formation is interpreted as sub out cropping in the northern part of the claim group and underlying

4 the other formations on the remainder of the group. Descriptions of the iron formation may be found in the literature (Bibliography ref. 1,2 fc 3)* Graphitic Shale (Rove Fm.) Graphitic shale outcrops at a number of places along the cliff-face which marks the diabase-shale contact. Work on adja cent properties has established an average thickness of 100m for this unit. Exposures of this formation show a fissile black shale with beds l to 6mra thick and averaging 2-3rom. The black colour is due to graphite and probably vory finely divided pyrite. A carbon determination of this formation from an adjacent area gave 3*26/5 C. These shales normally have anomalously high contents of metals. A sample of this shale from an adjacent area gave a serai-quantitatives analysis of 0.5 to 2.0/S Zn. Additional descriptions of these shales' are available in Bibliography references l, 2 St 3 * Diabase (Logan Type) The diabase is typical of the area in that it shows the features described in the literature (Bibliography ref* l, 2 fc 3) The diabase is generally fine-grained (Iran) but at the shale-diabase contact the grain size is very fine normally for only a thickness of a few centimeters. Occasionally the average grain size increases to 2mm but no systematic variation was

5 found, except for the narrow contact zone. Exposed thickness of the diabase is about 20 metres. Surficial Deposits Several types of Pleistocene and recent deposits occur on the property. The oldest is considered to be the boulder till which occupies an arc-shaped area across the property, more or less following the contour of the hill. Typically it consists of a brown clay-loam containing well-rounded boulders. The boul ders consist predominantly of granite, greenstone and granite porphyry with lesser amounts of granitic gneiss and minor iron formation and diabase. The boulders are typical of the bedrock 5 to 50km north of the property. North and west of the till and down-slope is brown to red clay and clay-loam. This is considered to be derived from the boulder till by oxidation and water transport of the finer fractions of the till. The area underlain by diabase is covered with thin boul der till containing numerous iron formation pebbles and cobbles and locally derived angular diabase fragments* Paralleling the shale-diabase contact is talus composed of angular blocks of diabase. The lower edge of the talus is mixed with boulder till. Swamp deposits are small and thin.

6 Structure, Metamorphism and Alteration The property is structurally simple. The sequence is conformable and dips gently (3-? degrees) to the south or southeast. The faults (known and assumed) have resulted in vertical displacement but (except for possible very local reverses in dip) have not affected the structure. Metamorphism is restricted to the chill zone at the shalediabase contact. Adjacent to this zone the shale is bleached to a light grey and indurated for 10-20cm from the contact. Bedding in this zone is partially destroyed, with partings commonly l-3cm apart instead of the usual 2-3mm. Alteration is apparent along the known fault zone. Faulting and shearing has produced a green "chloritic" gouge in the diabase, and a light grey gouge in shale* Shale adjacent to the fault is usually bleached to a grey colour and often silicified. Calcite which occurs in the veins filling the fault fissures has been extensively leached by surface water to a depth of several feet. ECONOMIC GEOLOGY The major economic feature of the property is the fault zone crossing the southern part of the property. Much of the work to date has been concentrated on this zone. Where exposed in the diabase by bulldozer trenching, the fault zone appears to consist of two distinct breccia zones. The couthern zone consists of several stringers up to 10cm wide

7 6. containing quartz with minor purple fluoritet Calcite was also present but has been leached out. This zone is 2-Inn wide and the stringers strike about east-west. Vein material constitutes of this zone. Several meters of rather massive and unfractured diabase separate the north zone from the southern zone. This north ern zone consists of a random network of stringers cementing l-3cm fragments of diabase. Vein minerals consist of quartz with purple, green and white fluorite. Minor calcite was also present but has been leached out. Vein material repre sents & of the 0.5m diameter exposure. No strike could be determined. Exposure of the fault zone in the 1979 stripping indicate a brecciated zone in the shales for a width of 60m. Usually only an occasional quartz stringer l-5mm is present, however at several points zones up to 30cm or so of quartz, green and purple fluorite and heavily leached calcite occur between shale, fragments. In these zones vein material may constitute up to of the width. Pyrite occurs erratically along joints and bedding planes throughout this zone. Other metallic minerals were not found in tile exposures of the vein although galena and phalerite were found in several pieces of float immediately overlying bedrock and on the dump from the adit. Barite was also found in float. The vein zone exposed in the adit was not examined due to

8 the water in the workings and the poor condition of the back. The adit has a length of metres with a vein zone exposed in the back for the entire length. Material on the dump indicates the vein in the adit is up to UOcm thick and contains quartz, calcite, green and purple fluorspar (and barite?). Metallic minerals include pyrite, galena and sphalerite. No silver minerals were identified in the veins. Titano-magnetite is present in the diabase in small quantities (1-3/0 but is not of economic significance. The boulder till on the claims is an excellent-looking soil and would likely be saleable after removal of the boulders* The trench on line 5E exposes a minimum thickness of 1.5m of this material. The black shale is excellent road base material and may be saleable for this purpose. The location and access to this area would be major ob stacles to commercial use of these industrial minerals. Certain portions of the veins would be attractive when cut and polished for decorative purposes. RECOMMENDATION The following future work is recommended: 1) Completion of the geochemical survey This will assist in isolating zones within the fault zone which contains significant quantities of metallic miner-

9 als and outline other vein zones on the property* 2) Magnetometer survey A magnetometer survey would assist in determining if the fault zone in the diabase is a single zone or actually the junction of two or more faults as is suspected. The lo cation of the shale-i.f. contact would also be indicated. 3) Sampling A series of samples along the trench in the shale west of line 6E would indicate if silver values are present in the shale and veinlets.
