- FELDSPAR
Copper King is quite interesting -
The Copper King occurrence is located approximately 1,300 m east of the GBRM portal. The workings comprise two adits, the lower of which is no longer accessible. The upper adit is approximately 80 m in length and was excavated along a 30 m wide east trending diorite dyke. At approximately 15 m along the west-bearing adit, a 20 m long shaft was driven to surface (ten metres) and sunk ten metres below the level. A second shaft was sunk 15 m near the western extent of the adit and several small crosscuts were driven off the access. The adit terminated with a 30cm vein exposed that was mineralized with pyrrhotite and minor chalcopyrite and arsenopyrite (Mosher, 2003).
The mineralization is associated with three east/west trending diorite dykes that dip between 70° north to vertical. The individual dykes range from 24 m to 43 m wide for an aggregate width of approximately 91 m
Wango - those are very nice dykes.
I like the widths.
Appears the copper is not in the pyrite - cleaner copper ?
But... there's also - Feldspar -
yet, another nearby showing that has something very interesting going on.
480m of porphyry material was intersected.
What did they find ?
Keep reading.
The Feldspar deposit, located approximately five kilometres west of GBRM, is a feldspar porphyry intrusive measuring approximately 2,800 m by 800 m that has been identified by airborne (DIGHEM) geophysics.
In 1987, while testing the extent of the GBRM deposit, a vertical diamond drill hole intersected 480 m of porphyry material.
In 1992, a DIGHEM airborne geophysical program identified a large magnetic anomaly in the area (Masters, 1996). In 1994, surface mapping and two percussion drill holes were utilized to delineate the extent of the deposit. Chip samples from the drilling were taken every 0.61 m (two feet).
Core samples and chip samples were composited, crushed, pulverized, and subjected to whole rock analysis. Eight core samples were submitted to Vancouver Petrographics for detailed description.
The samples were found to be quartz-free, feldspar-rich intrusive rocks made up of euhedral phenocrysts of andesine in relatively coarse, granular/interlocking groundmass of feldspar and accessory hornblende and/or pyroxene.
No nepheline or other feldspathoids were recognized. Three of the samples were classified as monzonite and five were classified as diorite.
Minor disseminated magnetite and traces of pyrite were noted (Masters, 1994). Twelve additional percussion holes were drilled in 1996 and sampled every 1.52 m. A total of 779 samples were logged for mineralogy, grain size proportion, and colour. Samples were cut and analyzed for iron content (Masters, 1997).
In 1996, additional petrographic studies were done at the Earth Mechanics Institute at the Colorado School of Mines that identified the deposit as monzonite-diorite in composition (de Souza, 1999). No criteria were given for the samples selected.
Twelve percussion holes were drilled in 1996 (Anderson, 2000). In 1997 and 1998, process testing was done in an attempt to remove the iron content (de Souza, 1999). RPA was not able to determine the outcome of these investigations.
In 1998, diamond drill holes replaced percussion holes and were concentrated on the western portion of the intrusive body. Holes were drilled using NQ (47.6 mm diameter) and BQ (36.4 mm diameter) size equipment. The core was visually classified into different alteration types and some core was tested for magnetic susceptibility using a KT-9 Kappameter (Anderson, 2000).Using visual classification and magnetic susceptibility readings, Bul River geologists were able to estimate the total iron content within specific alteration domains without waiting for chemical analysis.
Wango - Did you read what was found ?
Or, to ofocused on the iron ?
The Colorado School of Mines determined - Monzanite.
What's Monzanite ?
Monazite is a primary ore of several rare earth metals most notably thorium, cerium and lanthanum. All these metals have various industrial uses and are considered quite valuable.

i wonder if Braveheart could compile al lthe datsa on this - search out all the intel and compile a page on their website to detail this - Feldspar - showing all the more.
If the cores are still avail- would it ever be nice ot see if there is - Thorium - with in.
Here's a quick rundown on -
removing throium from ores.
PRETREATMENT CIRCUT FOR - THORIUM - ( smart processing )
Because of low grade of thorium and uranium in the Zarigan mineral deposit, the pre-concentration operation prior to leaching is necessary. From X-ray diffraction analysis results, it was clear that this ore has large amount of other minerals such as Feldespat, Quartz, Hematite, Titanomagnetite, and rare earths. In this paper the thorium enhancement grade in Zarigan deposit by using gravity, magnetic and electrical separations methods is reported. The output of a Jaw crusher was ground to 85 micron by using ball mill. Then about 95% of SiO2 was separated by using shaking table separation. The heavy concentrate of shaking table was processed by a high intensity magnetic separator and then the magnetic concentrate separated by a low intensity magnetic separator. Finally, the non magnetic concentrate of low magnetic separator was processed with the electrical separation. The grades of thorium and uranium in the non magnetic concentrate of low magnetic separator were increased to 4000 and 5000 ppm, respectively where only 15% of the initial feed (ore) was transferred to this concentrate. Therefore, this resulted in a decrease of acid consumption in the leaching processes and the efficiency enhancement of the process. The pre-treatment circuit of this ore was designed as Jaw crusher/ball mill/shaking table/high-magnetic separator/low-magnetic separator/electrical separator, respectively.

Cheers....
Ha... to answer the poster who asked for a forecast price ?
Show me the cobalt values first - in the mines - scanning the open cut walls.
And.. .yeah... i'd take a poke at a valuation - lol
I would want a thorough scanning of all the walls, up - down and around.
Cobalite is known to reside in argilites.
I found the tech reports - those who explored for copper, gold, silver... were too focused on the veining.
In another report, the copper was also found in the argilites - in quasi veining - or, sprawled veining. Thius suggests, the mineralization is not specific to just the veins.
Hence - consider that most of the ore analyzed was just from the veining.
The whole scope on ores needs ot be reevaluated- my own opinion.
Especially whewn cobalite is present.
$53,000+ per tonne.
