Geological Fieldwork 2009

The pro vi sion of ac ces si ble, new geoscience data about Brit ish Co lum bia is aimed pri mar ily at in creas ing min eral ten -ure ac qui si tion and min eral ex plo ra tion ac tiv ity in the prov ince. The Brit ish Co lum bia Geo log i cal Sur vey (BCGS) pres entshere the re sults of field sur veys and geoscience re search for 2009 in a thirty-fifth edi tion of Geo log i cal Field work. Most ar ti -cles are con tri bu tions by sur vey staff to the un der stand ing of the ge ol ogy, geo chem is try and min eral de pos its of the prov -ince. The vol ume also in cludes con tri bu tions about col lab o ra tive re search with other or ga ni za tions and projects completedby other professional geoscientists.

British Columbia Geological Survey Successes

· The BCGS, in part ner ship with Geoscience BC, Smithers Ex plo ra tion Group and the North west Com mu nity Col lege,be gan a surficial ge ol ogy and till sam pling pro gram south east of Hous ton. Pre lim i nary work in di cates that cover by gla -cial de pos its in this part of the Nechako Pla teau is not as ex ten sive as pre vi ously thought.

· The first sea son of the north coast pro ject, car ried out jointly with the Geo log i cal Sur vey of Can ada (GSC), cov ered anarea of 30 by 50 km. Map ping on Porcher Is land and along the ad ja cent Grenville Chan nel found geo log i cal in di ca torscom monly as so ci ated with volcanogenic mas sive sul phide de pos its.

· The Iskut River pro ject com menced in the fall with a 10-day field sea son. A part ner ship with the Uni ver sity of Vic to ria,Pa cific North West Cap i tal Corp and the GSC, the ob jec tive is to in ves ti gate min er al iza tion within the Coast Belt ofnorth west ern Brit ish Co lum bia.

· Our on line in ter face MapPlace and its sup port ing site now ex ceed 11 000 web pages. Used 24 hours a day, 7 days aweek by the ex plo ra tion com mu nity world wide, this in ter face plays an es sen tial and grow ing role in at tract ing in vest -ment to the prov ince.

· Nu mer ous min eral re source as sess ments to fa cil i tate gov ern ment land use plan ning were com pleted.

· The Prop erty File da ta base cap tured 2860 new doc u ments and maps for the QUEST area and 1540 for other ar eas, while 481 MINFILE oc cur rences were up dated and 17 new ones iden ti fied. Con tracts for both pro jects were funded byGeoscience BC.

· BCGeology Map, BC’s dig i tal ge ol ogy map, is un der go ing its first ma jor up date since re lease in 2005. Through out2009, a team from the BCGS, Geoscience BC and the GSC worked to up date the Quesnel Trough ge ol ogy for theQUEST geo phys i cal area.

· Sur vey staff up dated our website and moved serv ers as part of a gov ern ment-wide ini tia tive.

· The BC Min eral De vel op ment Of fice in Van cou ver hosted na tional and in ter na tional del e ga tions of po ten tial in ves torsand was a key player in or ga niz ing the Asia In vest ment Mis sion.

· Sur vey ge ol o gists were or ga niz ers and pre sent ers at con fer ences and work shops around the prov ince, and led in dus tryfield trips in the north east ern coal fields and the Merritt and Prince ton ar eas, as well as a cop per-gold mine tour.

· The BCGS hosted its first Open House of the 21st cen tury in Vic to ria in the fall. The event was a suc cess, with more than85 par tic i pants, and will be con tin ued in 2010.
