Internship Information

Mineralogy — Sun, 05 Sep 2010 09:44:59 +0000

Each semester, the faculty, staff, and students of the Georgia Museum of Natural History welcome undergraduates as Natural History Interns to enjoy a hands-on course with the Museum. Interns receive supervised experience working directly with the faculty, staff, and other students curating one of the natural history collections affiliated with the Georgia Museum of Natural History or with education and outreach programs.

The course objective is for Interns to learn about museums of natural history and natural history collections by working closely with collection staff collecting, accessioning, preparing, cataloging, and curating natural history collections or with education staff interpretating natural history to the public. Students will practice techniques and methods for curating materials in one or more collections under the direction of collection personnel. Routine curatorial practices such as identification and preparation of specimens and data management will be part of the Internship. In addition, Interns may participate in tours, outreach presentations at area schools, special events, preparation of displays, and occasional weekend field trips.

American Manganese Inc

Mineralogy — Thu, 02 Sep 2010 20:40:58 +0000

Mr. Larry W. Reaugh, President and Chief Executive Officer of American Manganese Inc.(“American Manganese” or the “Company”), (TSX.V: AMY; Pink Sheets: AMYZF), is pleased to announce the Company has received results from its on going Artillery Peak drilling program for drill hole numbers 49 – 53 located on the South Maggie zone of the Manganese Mesa from its on going Artillery Peak drilling program. Results for drill holes 1 through 48 have been announced previously.

“The Artillery Peak manganese mineralization is located within basin filling alluvial fan/playa deposit which typically exhibit large thickness and lateral continuity” says Mr. Reaugh. He goes on to say: “According to the US Geological Survey, Bulletin 961, the bedded deposits of the Chapin Wash formation have the potential for hosting immense tonnage of prospective manganese mineralization. The success of this drilling program demonstrates that character and continuity.”

The Minerals

Descloizite
Descloizite occurs throughout the mine and is locally plentiful. The crystals are generally sharp and vary in color from red to green to black, larger crystals tend to be distorted.

Sharp rosettes of blood-red descloizite make striking specimens.

Fluorite
Fluorite is rarely found and is one of the earliest minerals to have formed and is always massive. In the back of one small stope several tons of massive purple fluorite occurs with secondary copper minerals.

Galena
Galena has been found as residual pieces and occasionally forms the matrix for secondary lead minerals.

Gold
Historic documents report a small quantity of gold being present in the ore. Likely, if a sizable ore sample was to be crushed and panned, free gold would be obtained.

Red Chris Exploration Program Continues to Expand Deep Deposit

Vancouver, BC – August 5, 2010 - Imperial Metals Corporation (TSX:III) reports assay results from ongoing exploration drilling at its Red Chris property. Results from drill hole RC10-393 include 317.5 metres grading 1.08% copper, 1.46 g/t gold and 4.28 g/t silver within a 1,112.5 metre mineralized section grading 0.54% copper, 0.61 g/t gold and 1.96 g/t silver. This is one of the longest mineralized intercepts obtained to date at Red Chris. RC10-388, one of the first holes in the deep Main zone since 2007, tested the western edge of the known Main zone and intersected five intervals of copper/gold mineralization including 380.0 metres grading 0.34% copper and 0.50 g/t gold.
Final results from RC10-360* have extended the length of the previously reported high grade interval to 671.2 metres grading 1.03% copper and 1.65 g/t gold. This intercept strengthens confidence in high grade mineralization observed to the west in RC07-338 and to the east in RC09-350. More drilling will be required to fully define the geometry of the high gold to copper ratio mineralization in this area. (*partial results were released April 12, 2010)

The East zone mineralization has been extended with RC10-375 intersecting 861.7 metres grading 0.41% copper and 0.38 g/t gold including a 302.5 metre section grading 0.56% copper and 0.54 g/t gold. This step out is the most easterly deep drill hole in the East zone. Mineralization at depth in this area is still open to the east. Also drilled in the East zone, RC10-391, located 125 metres northeast of RC10-393, returned 1,002.5 metres grading 0.50% copper and 0.38 g/t gold while nearby RC10-393 returned 1,107.5 metres grading 0.54% copper and 0.61 g/t gold. RC10-391 and 393 were drilled in an area to the east of RC07-335 where previous attempts to drill deep had been unsuccessful.

University of Western Ontario

Mineralogy — Sun, 22 Aug 2010 12:47:10 +0000

Dr. Roberta Flemming at the Department of Earth Sciences at University of Western Ontario has openings for M.Sc. or Ph.D. candidates interested in pursuing fundamental or applied studies of minerals in the following areas:

Fundamental understanding and quantification of mineral behavior as a function of pressure (P), temperature (T) and composition (X). Projects involve mineral synthesis (at controlled P-T), and determination of crystal structure (by X-ray diffraction/Rietveld refinement), crystal chemistry (by EPMA), and cation order-disorder (by Nuclear Magnetic Resonance (NMR) spectroscopy (e.g. 29 Si NMR provides a measure of Si/Al order in aluminosilicates). These data have application in geothermobarometry.

Systematic investigation of Kimberlite Indicator Minerals (KIM) (e.g. chromite, Cr-diopside). Variation in unit cell parameters (measured by µXRD) is correlated to geochemical data (by EPMA), on a grain-by-grain basis, with the aim of developing µXRD as a tool for diamond exploration. Inclusions and strain, observed by µXRD, give additional clues to origin.
Systematic mineralogical investigation of meteorites. In situ µXRD provides rapid mineral ID for meteorite classification, as well as unit cell parameters for addition to our growing database of unit cell parameters for meteorite minerals. Unit cell parameters can be correlated to geochemical information, and in some cases (e.g. clinopyroxene and olivine in basaltic meteorites) this may be correlated to planetary origin. Rietveld refinement of powder XRD data provides modal mineral analysis of bulk sample, and enables crystal structural study of selected phases.
Development of micro X-ray diffraction (µXRD) as a tool for geologists. Micro XRD provides a unique opportunity to correlate crystal structural information with other microanalytical data on the microscopic scale (50-500 µm) not previously available routinely. Furthermore, minerals can be examined in situ, preserving orientational information. Projects include:
1. Quantification of strain-related mosaicity in minerals in meteorites, impact structures, and other rocks, with an aim toward development of a µXRD strain index and calibration using existing strain indices.
2. Development of µXRD for exsolution geothermometry. (e.g. two pyroxenes). GADDS image provides simultaneous unit cell information for both phases, as well as their T-dependent orientational relationship.

Facilities at UWO include a Bruker D8 Discover micro X-ray diffractometer, High-T and High-P laboratories, EPMA, SEM, FTIR, Raman, and XRF facilities (Earth Sciences), 400 and 600 MHz solid-state NMRs (Chemistry), XPS and SIMS facilities (Surface Science Western).

If you wish to obtain more information about these projects, or other possible projects, please contact Dr. Roberta Flemming (519-661-3143, rflemmin@uwo.ca). Collaborative projects with other faculty are also possible. Research and teaching assistantships are guaranteed for all qualified students.

The Minerals

Aragonite

Colorless crystals of aragonite are fairly common and widespread throughout the mine. The crystals rarely exceed 1cm in length.

Aurichalcite

Pale tufts of aurichalcite have been found with wulfenite and hemimorphite in a narrow fracture about half way to the bottom of the mine. The aurichalcite crystals reach a few millimeters in size.

Barite

Massive white barite is locally present; the barite is coarsely crystalline and occasionally forms the matrix of specimens.

Calcite

Calcite is widespread throughout the mine. Colorless to white calcite crystals can be found lining vugs and fractures. Calcite is commonly the last mineral to have formed.

Cerussite

Colorless to grey cerussite crystals to 6cm have been found in localized areas. The crystals are generally crude and rounded although sharp colorless microcrystals have been found.

Chalcopyrite

A single chalcopyrite crystal was found in massive galena.

Chlorargyrite

Crude crystals of yellow-green chlorargyrite have been recovered from the lower reaches of the mine. The crystals rarely exceed 4mm and generally have a “melted” appearance. Chlorargyrite has been found with both residual sulfides and hemimorphite.
