Geological Survey Field
Projects: 2009
The
addition of $1 million to the Survey budget from 2008-11,
combined with the recruitment of several new project
geologists means that the Geological Survey will be
mounting its most extensive field season in at least a
decade, with 14 field projects planned, employing over 20
summer students.
LABRADOR
Tim
van Nostrand will be working on the Seal Lake Group again
this year, with a 2-month field season planned, and a
4-person field crew. This is the second year of this
1:50,000 scale bedrock mapping project, in an area of
numerous mineral occurrences.
New
hire
Peter
Valley
will spend 2 months mapping the bedrock in the
Knox
Lake
area, north of the Smallwood Reservoir. The area has been
previously mapped only at a reconnaissance scale. The area
is part of the
Churchill
Province
and has few known mineral showings - the area to the north
in
Quebec
is considered prospective for gold and base metals. The
project is part of a collaborative effort with the
Geological Survey of Canada, and the Quebec Survey. The GSC
has flown a detailed aeromagnetic survey in this area over
the winter, and the Quebec Survey will have a mapping crew
across the border in adjacent
Quebec
.
Geochemist
Steve
Amor will also be working in this area, with a
helicopter supported 4-week detailed lake sediment sampling
project.
Greg
Sparkes will continue his work in the Central Mineral
Belt, studying uranium mineralization. This will be the
final field season of this project, and Greg will be
visiting various showings and prospects, based out of
Goose
Bay. A
2-month field season is planned, with the objective of
completing coverage and sampling in the Central Mineral
Belt to the greatest extent possible. Areas of interest
elsewhere in
Labrador
accessible by road will also be examined briefly, if time
permits (e.g., the Labrador Straits area).
Charlie
Gower is planning a short field season, taking advantage of
road construction in southern
Labrador
to field check his major compilation map for the eastern
Grenville.
NEWFOUNDLAND
Ian
Knight, with palaeontological support from Doug
Boyce, will finish up mapping of the Lomond (NTS
12H/05),
Pasadena
(NTS 12H/04) and adjoining (NTS 12H/03 and 06) map areas.
Both will also spend time on the
Port-au-Port
Peninsula
examining stratigraphic problems. These studies of the
Cambrian Ordovician clastic-carbonate terrain of western
Newfoundland
are important to the emerging on-shore and near-shore
petroleum exploration efforts, as well as to uranium
exploration in the area.
Alana
Hinchey will be working in the
Long
Range
Mountains
in the
Silver
Mountain
area (parts of NTS 12H/11, 14). Recent road construction
has greatly improved exposure in the area; therefore, much
will be gained by updating the geological mapping and rock
sampling of these poorly known rocks. The area also
contains an active gold exploration project. This is a
3-month field project, based out of western
White
Bay.
Brian
O¹Brien will conclude mapping of the Catchers Pond Group
and adjacent rocks through a 3-month field season in the
Kings Point area. This is an area of considerable
structural complexity and high mineral potential.
Understanding the structure, chronology, and
lithogeochemistry of this area will lead to an improved
understanding of the geological history, and will be of
benefit to mineral exploration.
Jennifer
Smith will continue the
Red
Indian
Lake
Basin
surficial mapping and till geochemistry project. This
project began in 2007, as a result of increased mineral
exploration activity in the Tulks Volcanic Belt.
Mineralized boulders, found in thick glacial drift, have
created a demand for a better understanding of the palaeo
ice-flow history to aid in the exploration, and possible
discovery of, new resources. This program will provide
support to the current exploration efforts and may also
stimulate mineral exploration activity in more inaccessible
parts of the area.
Denise
Brushett will start a new project in the
Gander
area. This project will provide a Quaternary geology
framework for the evaluation of geochemical data collected
in the field to support mineral exploration. The study area
is prospective for mineral exploration, particularly gold,
and could be assisted by detailed surficial mapping. The
2009 field component will focus on sampling and mapping in
areas north and east of
Gander
Lake
that have not been covered in previous surveys, and will
include sampling of tills for geochemistry.
Hamish
Sandeman will embark on his second field season examining
gold metallogeny in central
Newfoundland.
Information
on gold-mineralizing environments in some areas was studied
in previous Survey projects, but many other areas remain to
be covered, and some geological aspects of gold
mineralization remain poorly understood. There are
presently several areas in which new styles of
mineralization may occur, or in which renewed exploration
provides important new information for reassessment.
There
will be two projects focusing on the
Bonavista
Peninsula
this summer. New hire Leon
Normore will be mapping the bedrock of NTS map
areas 2C/11 (Bonavista) and 2C/06 (Trinity). This remapping
and detailed analysis of the Conception, St. John¹s and
Signal Hill groups, within previously designated
Musgravetown Group areas, will complete the project started
by Sean O'Brien. The area has considerable interest for
geotourism following the discovery of soft-bodied Ediacaran
fossil assemblages by Sean O¹Brien and others, but also
has potential for sediment-hosted copper mineralization.
The
copper mineralization in the Bonavista area will be
investigated by John
Hinchey. From the late 1990s to about 2004, there
was industry interest in these deposits on the
Bonavista
Peninsula
.
Although no economic discoveries were made, it is
anticipated that there will someday be renewed interest in
this deposit type as an exploration target in
Newfoundland
.
Compilation of previous work, and its augmentation with
focused research that will link industry data, will
significantly aid such efforts in the future. John will be
spending approximately 2 months in the field.
Jerry
Ricketts will continue evaluating granular aggregate
potential in eastern
Newfoundland
this summer. A 3-month project will concentrate on NTS
areas 1N/12 and 1N/13, between Whitbourne and Clarenville.
Data provided from this project will not only be useful for
construction projects within the immediate study area, but
may also be used in the northeast Avalon Peninsula,
Clarenville, and may have potential for use in the next
concrete oil production platform, proposed to be built at
Bull Arm.
Steve
Amor will be conducting field work as a contribution
towards the North American Soil Geochemical Landscapes
Project, a tri-national initiative between the
USA
,
Canada
and
Mexico
.
This was established to meet the need for soil geochemical
data by providing a consistent national and
continental-scale framework and database. Steve will be
sampling over a wide area of the province to assist in the
compilation of this major geochemical data set.
