چکیده
In 2004, the BC Min is try of En ergy, Mines and Pe tro leum Re sources and Boot leg Ex plo ra tion Inc. en tered into a part ner ship agree ment aimed at the eval u a tion of the re gional po ten tial for in tru sive-re lated gold min er al iza tion near Ter race, Brit ish Co lum bia. Boot leg Ex plo ra tion Inc. is a wholly owned sub sid iary of Ea gle Plains Re sources Ltd., and their area of in ter est is around Kitsum – Kalum Lake, cen tred ap prox i mately 35 km north of Ter race (Fig. 1). Pre lim i nary re sults from that part ner ship were pub lished in Mihalynuk and Fried man (2005). Geo chron ol ogi cal data that have come available since then are reported here.

GEOLOGY AND U-Pb GEOCHRONOLOGY OF INTRUSIVE ROCKS ASSOCIATED WITH MINERALIZATION IN THE NORTHERN TAHTSA LAKE DISTRICT, WEST-CENTRAL BRITISH COLUMBIA
The Bulkley Suite of intrusions are spatially associated with numerous important mineral occurrences in westcentral British Columbia. Previous K-Ar dating studies indicated that the Bulkley Suite ranges in age from 70 to 84 Ma (Carter, 1981). The purpose of this study is to better constrain the timing of Bulkley Suite magmatism and associated mineralization in the northern Tahtsa Lake District....

Bot-e-Gaz prospect area is located 34 km north of Torbate-e-Jam, Khorasan Razavi Province. Geology of the area includes diorite, granodiorite, and syenogranite intrusinos that intruded in metamorphic rocks. Magnetic susceptibility of intrusive rocks is <5× 10-5 SI and belong to ilmenite series (reduced type). These intrusive rocks are metaluminous to peraluminous and vary from medium potassium ...
