The piece has several tiny native gold flecks, the largest (and only easily visible one) about 3mm across. Homestake was the largest and deepest gold mine in North America before it closed at the end of 2001, and despite its lean ore, produced over 40 million ounces of gold during its lifetime. A classic locality piece with my original label, overall size about 4x3cm @ 125.00.instructions.

GYPSUM- Alabaster, Iosco Co., Michigan
A large and weighty specimen comprised of a peachy-orange, columnar mass of gypsum, obviously removed from a thick seam, as this is an apparent cross-section with hints of matrix at top and bottom of this weirdly-hued monster. A large and colorfull locality specimen that some would consider as the variety selenite due to its translucent nature. The specimen is an impressive 16cm tall & about 9cm across, quite solid and heavy just 75.00.

GYPSUM (ROSE)- Permian Cu Deposits, Stonewall Co., Texas
Well formed, complex groups of gypsum roses nicely intergrown and forming attractive groups without matrix, colors ranging from greyish to brownish red. The individual blades are typically thin and flattened but radiate into multiples forming the bladed groupings. Old material from a relatively obscure area of Texas, acquired circa 1962 (!!).

PYROMORPHITE- Bunker Hill Mi, Kellogg, Shoshone Co., Idaho
This famous property operated sporadically from 1886 to 1994, producing a wide range of minerals and various colors of pyromorphite along the way. These samples were acquired circa 1960, long before the modern heyday of collectible specimens came to market. The pyromorphites are in typical, barrel shaped, elongated crystals to 3mm sacattered on rusty quartz/rock matrix, the crystal color a pale greyish green reminiscent of those supplied by the late Ted Morley in the 1950s-1960s when the property was worked by the Bunker Hill Co., prior to the Gulf Resources and Chemical Co. takeover. Decent coverage on these generally small specimens, matirx sizes from about 2.5cm to 4.5cm @ 5.00, 10.00 and 20.00 each, or as smaller samples in lots of five for micromounting @ 12.00 per lot of five.

The locality is now known as the Mountain Ore Bank Mine. The crystal weighs a little under 2 lbs and is no beauty, but its relatively large size and off-beat locality provide much interest as a result. Size is 12x6x7cm @ 55.00; one only!

QUARTZ with inclusions- Chaiyaphum, Kaset Sombum District, Thailand
An unusual specimen comprised of three major quartz crystals to 4cm intergrown to form a complex stacked group of transparent, weirdly modified habits, admittedly with detachment at the bottom and some damage on some of the complex terminations. Most interesting, however, is under the 'scope which discloses pointed spear-shaped needles of quartz(?) pointing into the core of the specimen, as well as numerous hollow areas, floaters and growth chevrons evident as well at 10x or better. There is mild limonitic staining within the group, also enhancing its appearance at modest magnifications, highlighting some of the staggered growth patterns and voids within the sample. An uncommon locality piece, originally obtained nearly 30 years ago from Mountain Minerals International and residing in the private collection of Scott Williams. Both labels accompany this 5.5x4x3.5cm group @ 65.00. One only!

PATRONITE with "QUISQUEITE"- Minasragra, Cerro de Pasco, Peru
An old and rich specimen comprised of dark bluish-black patronite intimately intergrown with "quisqueite", alternately now known as either a highly sulfurous carbon compound or vanadium-rich lignite. The material was first described in 1906 in the Engineering and Mining Journal, and later in 1907 in the Journal of the American Chemical Society. A rich hand specimen, accompanied by a heavily deteriorated J. Cilen label (with strange blue crustymineral growths!) AND an orignal Lazard Cahn label showing spotty deterioration as well, specimen size about 9x7cm @ 125.00.

PLACER CONCENTRATES- Long Valley, Valley Co., Idaho
From our materail desccribed in Mineral News (2018) Vol. 34, No.6, these are heavy mineral concentrates from the Cascade area dredge jigs obtained by noted geologist and mineralogist Prof. E.W. Heinrich in the 1950s. Our analytical work on these fascinating tiny grains shows predominant ilmenite, and each 5x1.5cm vial will likely have associated spessartine, magnetite, columbite-(Mn), monazite -(Ce), euxenite-(Y), yellow titanite, trace fluorescent zircon and others! Great looking under the 'scope, and a "must-have" for sand collectors @ just 10.00 per 5cm vial.

PYROLUSITE variety POLIANITE- Lake Valley, Sierra Co., New Mexico
These are thickly intergrown, needle-like aggregates of pyrolusite forming radiating masses of greyish black "polianite" scattered in sooty, black matrix, some likely admixed with ramsdellite which is more typically in blocky aggregates and crystals. EDS analysis confirms simple Mn-oxide, and the morphology is a useful key as well to this obsolete varietal name often used to differentiate crystalline pyrolusite from its botryoidal forms. Old material, sure to turn your hands black upon handling, sizes from about 2.5cm to 5cm across @ 8.50, 15.00 and 25.00 each, with analytical copy!

QUARTZ- Crystal Peak, Incline Village, Nevada
A large single crystal of smoky quartz without matrix, overall stands about 31cm tall(!!!) and collected in the distant past. Only one on hand, a monster that is dark brown, translucent crystal that is singly terminated and prepped to stand upright @ 2000.00. The largest one we have ever seen from the locality. Yikes!

QUARTZ- Minas Gerais, Brazil
A very complex and appealing, large rehealed multi-crystal of quartz with hundreds of offsets, steps, and parallelgrowth faces, the largest faces being up to 3 cm across. The overall piece is rather flattened, and if studied carefully, appears to be a single, contiguous crystal (and doubly-terminated at that), despite the hundreds of separate vicinal faces on multiple terminations on the specimen. The quartz itself is colorless to lightly smoky, mostly transparent, and highly vitreous. Muscovite crystals and crystal fragments (to about 2 cm) are randomly embedded in the quartz, giving it even more of an unusual look. One termination has some damage to the tip, but otherwise there is little or no damage on the display side of the specimen. This is definitely a good piece for those collectors interested in complex and/or irregular crystal forms. Specimen size: whopping 12x8x4 cm @ only 60.00.

ROCKS & MINERALS- by E.P. Bottley
Author E.P. Bottley was best known as a London mineral dealer who purchased the J.R. Gregory dealership in 1931, becoming “Gregory & Bottley” and later “Gregory, Bottley & Lloyd” after his death in 1980 (many old collections have numerous specimens from this mineral concern, as do we in our warehouse.). His book, a hardcover, 95 page treatise, contains 113 color and black and white specimen images, and this lightly used and clean copy also has its original dust jacket. Size is about 26x21cm and is inexpensively offered at just 15.00 plus shipping.

EPHEMERA
PHELPS DODGE STOCKS
Perhaps one of the best known mining companies, Phelps Dodge was commonly associated with its operations at Bisbee and elsewhere in Arizona, but it also had extensive properties in New Mexico. Founded in 1834, it became the largest publicly traded copper mining company in the world when acquired by Freeport-McMoRan Copper & Gold in 2007. We recently located an old stash of Phelps Dodge Stock Certificates, these noted as interim shares issued in 1929 when the company offered a 4:1 split to its stockholders, only months before the market crash that led to the Great Depression. An orange-hued certificate was used for 100 share blocks, and a more rare, green certificate was used for smaller holdings. While we have seen these offered for as much as 30.00 each, we will send you one of each type for just 15.00 a pair! All are cancelled and are in generally good condition, showing normal wear. A neat piece of history!
GEM
TOPAZ- "Swiss Blue" Brazil
Excellent, faceted Brazilian topaz in an unusual 10mm heart shape, these are heat treated to yield a superb "Swiss Blue" color that is the most desirable of topaz hues. Well-cut, gemmy and fully transparent and eye-clean stones average over 4 carats each @ just 30.00 per stone, or a matched pair at 55.00. Very attractive!
