The program consisted of a Self-Potential geophysical survey and was undertaken between May 6’, and June 12”, 1998. The work follows a recommendation of A.B.L. Whittles, Ph.D. in his 1975 geophysical report on the property. It was felt that a closely spaced S.P. survey might be effective in locating small lenses of massive sulphide mineralization that previous wider spaced surveys may have not detected. The S.P. program was successml in locating detected several such targets. The survey went well and no unusual problems were encountered. Diamond drilling by Echo Bay Mines in 1989 confirmed the existence of high-grade minemlizaton at various depths down to 350 meters. Knowing that, it was hoped that some of those intersected mineral shoots might outcrop on the surface under a cover of overburden, and be detectable with S.P.. A summary of the favourable drill intersections of the “Echo Bay Program” has been included for the benefit of the reader as Appendex B. No mapping record appears to have existed for the underground workings on the claim group, so one day was spent doing that with belt chain & compass. Location and Access The Hilda Group is located at latitude 49’ 47’ 26” north and longitude 124’ 36’ 35” west in the Nanaimo Mining District of British Columbia. The property is located on Texada Island, some one hundred kilometers northwest of the City of Vancouver, in the Strait of Georgia. Access to the Island is by regularly scheduled air service from Vancouver to Gillies Bay, or by car ferry via B.C. Ferries from the town of Powell River. There is road access to the property from the village of Blubber Bay via 0.5 kilometers of paved road (B.C. Cement road). Hotel accommodations are available in Vananda and Gillies Bay. Histoxy Mining activity on Texada Island dates back to the turn of the century when several small mines were in operation in and around the town of Vananda near the north end of the Island. From these old producers, approximately 75,000 ounces of gold, 500,000 Ounces of silver and 19,000,OOO pounds of copper were recovered. The larger of these mines being The Marble Bay Mine, The Little Billie Mine, The Cornell Mine and The Copper Queen Mine. Several kilometers to the south, near the town of Gillies Bay, Texada Mines Ltd. operated a large underground and open pit mine at Welcome Bay between 1952 and 1976. Over 20 million tons of ore was mined yielding iron and copper concentrates and approximately 25,000 ounces of gold. At present there are three open pit limestone quarries in operation at the north end of the Island. Metals Research Corporation of America has a 100 ton per day gravity mill on It’s nearby Bolivar gold property on 1 Crescent Bay Road. The mill is not presently operational but I understand that with a limited amount of work it could be. Prover@ Description The Hilda Group consists of two 2 post mineral claims and one Fractional mineral claim. They are located at the head of Blubber Bay and extend from tidewater to an elevation of 100 meters. The surface tenure is held by Western Forest Products, however, the basemetals & industrial minerals are held by Ash Grove Cement West Inc. and Tilbury Cement. The precious metals are held by myself under the Mineral Tenure Act. As the Ash Grove’s “Blubber Bay Quarry expands eastward, the Hilda Fraction is destined to become part of that quarry within the next ten years. In fact, at the time of this report, Ash Grove has commenced a diamond drilling program to prove up limestone reserves on the Hilda Group. Also located on the Hilda Fraction are the workings of the old “Paris Mine”. These workings include four shallow shafts and one adit which provides access to a limited amount of drifting. The adit is assessable and does not pose any obvious hazards. Logging has taken place on the property intermittently over the past century. At present there is very little marketable timber on the property due to recent selective and clear-cut logging programs. A network of old logging “skid-roads” allows for easy access to most parts of the claim group. Ash Grove Cement utilizes the area for cat&rent of surface water for use in their mill and townsite. Regional Geolow Texada Island hosts the same geological units as central Vancouver Island. Karmutsen volcanics, consisting of flows of porphyrytic to amygdaloidal basalt and andesite, and Quatsino limestone, all of Triassic Age, underlay most of the Island. Highly altered andesite, tuff, limestone and pyroclastics of the Sicker Croup outcrop at the southern end of the Island. These rocks, of Permian Age, are the oldest on the Island. The volcanic and sedimentary units at the north end of the Island have been intruded by a number of diorite and quartz diorite stocks and dykes. it is in the area of these intrusions that economical mineral deposits have been located and mined in the past. Regional faulting is strongly developed on the island. Northwesterly trending faults dominate the structural setting. These large faults (some being traced for 10 to 15 kilometers) parallel the island’s axis, Malaspina Strait, and Georgia Strait. Lesser east- west trending faults cross-cut the predominate northwesterly faults in all regions of the Island. 2 Proaertv Geologv: The Claim Group is underlain almost exclusively by Upper Triassic Quatsino limestone of the Vancouver group. Inevitably, at some depth there will exist a basaltic or plutonic floor to the limestone, as is the case elsewhere on Texada Island. Intrusive activity is evident in the form of two diorite stocks and a well developed system of north-south diorite dykes. A predominate feature appears to be a solitary east-west trending quartz porphory dyke which cross-cuts the island from shore to shore. Bedding planes are evident on the eastern portion of the Hilda Fraction. Written reports from previous operators indicate that the property may have been host to a large geo-synclonic event. Recrystalization of the limestone and the limited extent of bedding planes exposure make confirmation of this difficult. Previous Work Underground exploration work is believed to have commenced around 1901. The property hosts four shallow shafts and one adit. The adit and subsequent drifting totals approximately 80 meters of tunneling. The underground workings accessible from the adit are on one level only and do not connect to the shafts above! No raises, winzes or stopes are present underground. A very limited amount of drifting is present at the bottom of the “main shaft” ( less than 10 meters ). The southernmost shaft has a small stockpile of high- grade copper ore ( 100 tons? ) piled up nearby. In addition to the shafts there are several surface pits and trenches, all appearing to have been excavated about the same time as the shafts. There is no record of any commercial production. Recent exploration programs are listed as follows: 1970 Bellex Mines Ltd. E.M. survey 1973 Longbar Minerals Ground magnetometer and VLF-EM surveys 1976 Aquarius Resources Ltd. Diamond Drilling ( no report available ) 1981 Aquarius Resources Ltd. 1.P & Magnetometer surveys and Soil geochem. 1985 Rbyolite Resources Inc. Magnetometer survey and Soil geochem. 1989 Echo Bay Mines Ltd. Airborne & Ground magnetometer surveys Rock & Soil geochem; I.P. Survey; Diamond drilling Geological mapping Mineralization Chalcopyrite, pyrrhotite, pyrite, sphalerite, magnatite, and native gold occur as massive sulfides in a metasomatic skam deposit at the contact of Quatsino limestone and two diorite stocks. Mineralization occurs in a gangue of garnet, epidote, pyroxene, actinolite, amphibole and wooiastinite. Some, but not all, of the north-south trending diorite dykes contain pyrite, pyrrhotite and minor chalcopyrite as fractire fillings and dissiminations. 3 Work Done The 1989 grid of Echo Bay Mines was remarked with fresh flagging, in the areas of the Hilda Fraction and the Hilda #3 mineral claim. Additional lines were flagged at 25 meter intervals. In total, 12.8 line/Km were flagged. A Self-Potential survey was undertaken on the Hilda Fraction and the Hida #3 mineral claim. One day was spent mapping and sampling the underground workings of the “Paris Mine” ( fig. 3, in pocket ). -. Geophysical Work For many years naturally occurring negative electrical ground potentials have been known to exist above some sulfide ore deposits. Several theories as to why this phenomenon occurs have been proposed. The most widely accepted theory seems to be that of Sato and Mooney 1960. They theorised that two electrochemical reactions take place within the ore body: one which is cathodic, above the water table, and one that is anodic, below the water table.

I further agree that permission for extensive copying of this thesis for scholarly purposes may be granted by the Head of my Department or by his or her representatives. It is understood that copying or publication of this thesis for financial gain shall not be allowed without my written permission. Department of School Of Community And Regional Planning The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 Date: April 1985 i i Abstract This thesis examines various approaches to public participation within rural planning. It deals with the roles rural residents, in unincorporated areas of British Columbia, can play in local planning. The thesis argues that effective planning in such areas only occurs if a rural planning approach, which considers distinctive rural characteristics, is. applied to the planning process. Such planning generally requires the active involvement of rural people. To accomplish this objective a model is constructed of how rural residents participate in planning.

This bulletinincludes reports of surveys of most of the knowncommercial or potentiallycommercial calcareous depositsreadily accessible tothe industrial and agricultural areas of south-western British Columbia and north-western Washington. Limestone deposits on the west coast of Vancouver Island and on the inland passage north of the difficultly navigable waters of Seymour Narrows, OkisolloChannel, and Yuculta Rapids have not, however, been examined. Deposits more than 4 or 5 miles from tide-water have likewise been omitted from the study, except in the eastern part of the Fraser Valley and in the western part of the Cascade Range of Washington whereadequate road 01- railtransportation is available. Unconsolidated calcareous deposits, marl, travertine, and shell, which are of someeconomic importance within this area, have been included in the study. Three introductory chapters dealing with the geology, extraction and utilization, and examination of these western limestone deposits have been included in this bulletin to aid in the appreciation of the reports on individual properties. Three months of the summer of 1944 were devoted to field-work on Texada Island, andtwo months of the summer of 1945 to field-work on VancouverIsland and the Lower Mainland.
