TEM plate modeling for KAN property in the Labrador

Posted by on Thursday, 28 June, 2012

Rio Silver Inc. has published The Results of EMIT Maxwell Plate Modeling and detail Resistivity Depth Imaging of VTEM anomalies for the KAN Gold Extension Project. The VTEM anomalies have been modeled by Geotech Ltd.

The Results of EMIT Maxwell Plate Modeling of VTEM anomalies for theKAN Gold Extension Project

________________________

The Kan project is located in the Labrador Trough of Northern Quebec, approximately 85km South West of Kuujjuag, Nunavik Territory.

Early exploration on the property was initiated by Cominco Ltd. (Cominco) in 1965 with the discovery of a massive
sulphide showing located under a sphalerite-galena-pyrite, glacial boulder train. Limited drilling by Cominco at the
time failed to define the extensions of this sedimentary exhalative (Sedex) base metal showing. Work resumed in
1993-1996 by Kennecott Canada Inc. (Kennecott) and then in 1999-2000, Noranda Exploration Ltd. (Noranda).
Kennecott discovered two more massive sulphide boulder trains located within 1.5km of the original discovery. The
average grade of 28 of these boulders is 7.7% lead, 9.7% zinc, 276g/t silver and 0.65g/t gold. Dimensions of some of
these boulders reach more than 2 meters across and their angular shapes point to local sources.

While Sedex base metals were the focus of exploration work on the Kan Property, several gold showings were
recorded in the historic assessment reports. The first gold occurrences were located during a Labrador Trough
precious metals reconnaissance campaign done by Noranda in 1987-88. Six grab samples reporting grades from
1.10g/t gold to 9.20 g/t gold were collected from an iron formation ridge located 1.5km east of the Kan showing.
There was no follow-up done on these gold results and this area will be a priority target for Rio Silver.

In 1993, during base metal reconnaissance work, Kennecott discovered a quartz vein cross-cutting iron formations
located 7km NW of the Kan showing. This vein (the Ferricrete showing) reported surface channel assays of up to
280.8g/t gold over 0.30m and 143.4 g/t gold over 0.40m. Four holes were drilled under the showing to test both the
vein and the host iron formations. Results from the drilling are reported below:

K94-11: 4.14g/t Au over 3.8m
K94-12: 6.29g/t Au over 3m and 1.24g/t Au over 2m
K94-21: 5.07g/t Au over 6m and 3.64g/t Au over 4m
K94-22: 4.01g/t Au over 1m and 1.64g/t over 1m.

Do not you forget what is an anomaly?

Posted by on Wednesday, 24 March, 2010
” We say “anomaly” all the time. What could be more obvious?

The SEG dictionary (Sheriff, 1991), spake thus:

1. A deviation from uniformity in physical properties; a perturbation from a normal, uniform, or predictable field.

2. Observed minus theoretical value.

3. A portion of a geophysical survey, such as magnetic or gravitational, which is different in appearance from the survey in general.

4. A gravity measurement which differs from the value predicted by some model, for example, a Bouguer or free-air anomaly (q.v.).

5. In seismic usage, generally synonymous with structure. Occasionally used for unexplained seismic events.

6. Especially, a deviation which is of exploration interest; a feature which may be associated with petroleum accumulation or mineral deposit.

7. An induced polarization anomaly is usually positive and greater than background (or the normal effect) to be economically interesting. In the frequency domain an anomalous region has a resistivity which decreases with frequency. An interesting re s i s t i v i t y anomaly is generally smaller than background.

Well, fine. These specific points are useful, as far as they go. But what do they add up to? Item 2 only seems to mathematize item 4, but 4 is unaccountably restricted only  to gravity surveys. And is an anomaly source generally a structure (item 5)? Is a geophysical anomaly the same as the geologic feature which is its source (items 1 and 5), or are these phenomena of different categories? Are only those anomalies deemed of exploration interest worthy of the title (item 6)? Why different anomaly definitions for different survey types?…”

Rock property database

Posted by on Thursday, 18 March, 2010

In this 2010 year the program Targeted Geoscience Initiative (TGI-3) is finishing. The Government of Canada committed $25M over five years to extend the mission of the Targeted Geoscience Initiative Program with a focus on base metal reserves in established mining communities. And through the TGI-3 program, additional petrophysical data will be added to the database for the TGI study areas (Southern B.C., Cantral Manitoba-Saskatchewan, Central Newfoundland, Abitibi, Ontario-Quebec, Bathurst, N.B.).

The National Rock Properties Database (NRPD) has been in development since 1998 and was initiated through a partnership between Noranda, Falconbridge, the Geological Survey of Canada, Quantec Geoscience Ltd, and Mira Geoscience Ltd. The result of the original development was a fairly complete data model and interface for the maintenance and query of rock property data collected using wireline geophysical methods. Through a partnership between McMaster University, MIRA Geoscience, and the GSC through the CAMIRO Project in 2004-05, the NRPD data model was extended to include rock property data measured on rock samples, definitions of universal lithology and alteration classifications for geological description.

The NRPD resides in an Oracle database. The database currently contains over 5 million rock property data records. Key parameters of each dataset include location coordinates, so that data can be queried by region, as well as geological attributes. The parameters currently available for query are Caliper, Conductivity, Density, Gamma, IP, Magnetic Susceptibility, Neutron porosity, Potassium, Resistivity, Self potential, Self potential gradient, Uranium, Temperature gradient, Temperature, Thorium and Acoustic velocity.
