In Pocket INTRODUCTION The Resource Data and Anaiysis Section of the Geological Branch is responsible for the collection, com- pilation, interpretation, and distribution of exploration and development data from various sources. Assess- ment reports are the primary source of detailed technical data on the mineral exploration and development industry. Beginning with this 1981 edition, Resource Data and Analysis Section is publishing preliminary computer listings based only on mineral assessment reports submitted. This change in format is expected to improve the timeliness of the release of the information toindustry. Eventually a final edition shall be published in a format similar to previous years. Our eventual aim is to be able to publish comprehensive and timely edition by extensive use of computer and word-processing systems. Most time-consuming activities such as ownership and total-claims-in-the-property searches, extended reference checks, and investigation of cursory information from other sources are omitted fromthis edition. ORGANIZATION The reports that form the body of this volume are arranged sequentially according to the assigned individ- ual report number, Numbers that are missing from the sequence near the beginning and the end of the series are included in 1980 and 1982 editions respectively. Index maps of 1 :I 000 000scale (reduced to 1:l 280 000)showing the distribution of current exploration by assessment report numbersare enclosed in the back pocket. Three index mapsare used: Figure 4, Southern British Columbia (NTS 82 and 92);Figure 5, Central British Columbia (NTS 83, 93, and 103); Figure 6, Northern British Columbia (NTS 94, 104,and 114). In the NTS designation, the whole of Canada is divided into primary quadrangles, each 4 degrees latitude by 8 degrees longitude. Each is described by a number, the last digit of which indicates latitude and the first one (or two) indicates longitude (for example, 104). British Columbia is covered by six of these primary quadrangles except for minor areas. Each primary quadrangle is subdivided into 16 map sheets, each 1 degree latitude by 2 degrees longitude, and described by letters A to P (for example, 104G) pro- ceeding from the southeast corner to the west in the southern panel, then east to the next panel, and so on. Each lettered quadrangle is subdivided into 16 map sheets, each 15 minutes latitude by 30 minutes longi- tude and numbered 1 to 16 in an analogous manner to the lettering (for example, 104G/7). Finally, each sheet is halved east and west for maps of the 1 :50 000 series and each is described (for example, 104G/7E and 104GI7W). LOCATIONS The latitude and longitude given is either the centre of the property or the area of major work. NTS designation is that of the main showing(s) or for the maiority of the claims. In cases where claims are located in more than one NTS sheet, several NTS designationsare given. ... 111 CLAIM NAMES The claim names include primarily those on which work was done. The computer program allows up to four names for each report. OPERATOR/AUTHOR(S) The individual or the company that did the work, paid for it, anddescribed the work in a report are recorded. GEOLOGY SUMMARY The known geological situation is briefly described according to lithological unit, age, structure, alteration, and mineralization. Commodities are listed if the mineralization is accurately describedlsupported by assay results. REFERENCES In this volume the references are limited to assessment reports describing work done onlnear the claims. Future volumesshall identify mineral occurrencenumbers where applicable, which are keyed to the Ministry's MlNFlLE information system. DETAILEDDATA Detailed property and technical data are described in the assessment reports which are confidential for a period of one year from the date of affidavit. The confidentiality period may be extended up to three years for regionalsurveys, and up to five years for drill-core assays upon request.Assessment reports that are off the confidential list may be viewed or copiedat district geologists' offices and: GeologicalBranch OR *Gold Commissioner's Office Mineral Resources Division Robson Square Room 421,617 Government Street 800 Hornby Street Victoria, B.C.
