ASSESSMENT WORK REPORT

ON

FOUR CLAIMS IN THE WEST PART

' OF THE

GILLIES LIMIT PROPERTY

INTRODUCTION

Part (1)

The purpose of this report is to describe an exploration program conducted on four unpatented claims in Block 4 and Block 10, in the North Part of Gillies Limit. The claims are numbered 298566, 298567, 298568, and 298569, and are held by Silverfields Mining Corporation of Ontario.

Part (2)

Consists of sixteen claims covered by a report by H.A. Moore, 1970 but conclusions were to sample this portion at closer intervals.

Part (1) claims lie west of the cottage road and south of existing claims in part (2).

An old abandoned farm of five acres is in part (1) claims close to Gillies Creek. Gillies Creek parallels the west boundary, while a hydro line bisects this group of claims, and extends south-easterly through the claims.

Part (1)

Thompson O,D.M. map 20?1 Cobalt Area shows Coleman sadiaents to underlay this group of claims with Keewatin volcanics to the east.

Upon a study of the Hector shaft area north of this group it would appear the Diabase dropped suddenly with the possibility that the Cobalt Lake Fault would project through this area giving this geologic feature. This could bo the reason for the bay at the junction with the Montreal River.

Diabano host rock ia not clearly featured by surface exposures, wheroas some outcrops near the river are covered by light glacial till and appear to bo Coleman sediments.

Part (2)

EXPLORATION TECHNIQUE.

The widespread overburden covering the property suggested tho biogeochemical soil sampling techniques to locate possible areas of silver cobalt oro mineralization.

Due to results acquired on Part (2) it was suggested we pick up this claL-a group and so a similar geochemistry survey.

The bush in this area is similar to Part (2) but a bit more dense, so the use of the A Ao horizon was used to collect samples.

Using the same technique to collect the samples, with drying, screening and ashing the sample was run by hot nitric method using an AA unit to determine parts per million in the sample.

A new frequency curve was established using all the samples on Part (l) plus Fart (2) being in number 4,563 saraples. Thia freq uency curve brings the background of j liver arid cobalt to a similar background reached by E. H. Hornbrook 1970.

Tho sample preparation wad changed due to the results in Figure (l) in 1970. Samples were screened to +100 ,nesh ir. 1970 while in 1971 saviples vere taken fron the whole portion of -60 mesh.

Part (1)

The first intermediate base line (1970) vas extended westerly with new hubs established at 200 foot intervals to encounter Gillies Creek comer post*

Linea were run south aid north to cover Silverfielda holdings with packets ot 100 foot intervals.

Tie lines were ran along ths youth boundary of the claims due to over run on staking, and irregular boundary lines.

Part ( 2)

A plan was established around the enriched areas to saapla at closer intervals.

New hubs were established for thn 300 foot interval linos and linos cut north ini south with pickets every hundred fBet.

Considerable time spent at the south end establishing in broken line aroas.

3AXPUNG

Part (1) and Part (2)

The aaae technique was used as 1^70, with samples be ir..; taken in August 1973..

Several, of the old lines were sampled in 1971 that could not be sampled in 1970 due to the low water conditions of the creok.

A total of 3,434 samples were taken. A location nap of the sample numbers and metal values are enclosed on 20 scale plans.

The samples wore dried, ashed, screened to -60 mesh, conod and quartered rcrl cent to Boniar Clegg Laboratory in Ottawa.

DISCUS3ION O? RESULTS

Work to date on Part One is of a preliminary nature designed to ^ive favourable areas in which more detailed sampling and ground study con bo conducted.

The percentage frequency diagrams for Cobalt and Silver values are presented herein. The 1970 and 1971 diagrams aro overlaid to indicate a more reasonable background. In assembling the statistics for them it is apparent closer interval spacing of the enriched areas have bought the threshold raoro in j. in D with Hornbrook work on Silverfields Mine report (1970).

At the present stage of sampling on both parta wide lateral migration of values which were not achieved by Hornbrook report because of the Diabase cover, could be explained by the fact that We are working directly over the Coleraan sediments.

The halos are the direct result of small fractures or vein systems of irregular mineralized veins which are common in the Cobalt area to be very errn'oic in mineral content. The possibility of similar vein structures to r,he north east and easterly boundary could exist similar to Silver*': olds Mine with some veins extending froa 4CO to 900 feet in length.

The following programme of exploration has been recommendedfor the 1972 field soanon.

(a) Sarcplo all anomalous areas in Part (l) over 25 parts per million cobalt at the minimum of 25 feet.

(b) Study soil cover arid bed rock depth of the anomalousareas.

(c) Diamond dril3 several of the high anomalous areas to test fox* mineralized fractures in the Coleman sediments and Keewatin volcanics.
