New Almaden Mining District, Santa Cruz Mountains, Santa Clara Co., California, USA (see the description of this locality on MINDAT). HgS-1  Mine Hill (see the description of this locality on MINDAT).  – Very rich, bright red cleavages and masses of Cinnabar are visible on all sides of the specimen. Specimen size:  4.3   X  2.8    X   3.2   cm minID: YHW-2Q0	HgS-2  Senator Mine (El Senador), Mine Hill (see the description of this locality on MINDAT). Extra rich massive, bright red Cinnabar is visible on all sides of the matrix. Bright red micro Cinnabar cleavages are scattered through the massive Cinnabar. Specimen size:  5.2   X 3.8   X    2.8  cm minID: NVX-Q17	HgS-3  Deep Gulch Placer Deposit (see the description of this locality on MINDAT) – Massive red Cinnabar is present as rich veinlets in matrix, from the historical Deep Gulch Placer Deposit discovered in 1945, in the stream that runs through the center of the small mining town of New Almaden.  This is an unweathered specimen, not stream worn, purchased from the daughter of one of the gentlemen who discovered and worked the Deep Gulch Placer Deposit.  She verified it is one of the specimens recovered from the surface workings in Deep Gulch, not a typical stream worn nugget. Specimen size:  5.2    X 4.5    X   3.3   cm minID: E80-DAF	HgS-4 Engine Shaft, New Guadalupe Mine, New Almaden Mining District (see the description of this locality on MINDAT). – Extra rich coatings of massive red Cinnabar are associated with metallic luster dark gray massive Metacinnabar.  Specimen collected January 2, 1974, from the David H. Reynolds collection # 1090.  Recovered from the Engine Shaft. Specimen size: 6.3      X  4.5   X 3.0     cm minID: 4L2-1LN	New Idria Mining District, San Benito County, California, USA  (see the description of this locality on MINDAT). HgS-5 New Idria Mine – Rich droplets of micro, bright native Mercury are associated with a broad, open veinlet of massive red Cinnabar, on matrix with small veins and masses of white Quartz. Specimen size:  4.5    X  4.2  X  4.0    cm minID: UY3-NWA
HgS-6 New Idria Mine – A thin vein of bright red massive Cinnabar crosses the center of the specimen. A small open vug in the center of the matrix is lined with rich micro droplets of bright native Mercury.  Minor white Quartz is associated. Specimen size:  6.2    X  3.3    X  1.8    cm minID: KA5-C6J	HgS-7 Molina Mine, New Idria Mining District (see the description of this locality on MINDAT) – This small prospect in the New Idria Mining District is known for its very dark gray-black matrix.  Rich amounts of massive to micro crystallized Pyrite cross the front and one side of the specimen.  Bright red micro crystallized and massive Cinnabar is intergrown with the Pyrite on the surface of the matrix, making for a very attractive and distinctive association. Specimen size: 5.2      X   4.2   X 2.3      cm minID: 118-MT9	HgS-8 Clear Creek Mine – From the famous Clear Creek Mine (Clear Creek Claim) in the New Idria Mining District, host for 12 new Mercury-bearing mineral species (type localities), this specimen is a simple silica-carbonate rock matrix with massive red Cinnabar spread across the front of the specimen.  Two small areas of micro drusy Quartz are present. From the collection of Edwin H. Oyler.  Edoylerite was named for him, from this locality. Specimen size: 9.0     X 6.0      X 3.3      cm minID: QDA-A2M	HgS-9 Clear Creek Mine – Bright red massive and micro crystalline Cinnabar coats much of the front of a silica-carbonate rock matrix. Specimen size:  7.0    X 3.5     X 1.5     cm minID: FQC-YCV	HgS-10 Clear Creek Mine – Bright red massive and micro crystalline Cinnabar coats about 40% of the surface of the silica-carbonate matrix, associated with minor Chalcedony . Specimen size: 6.5    X 4.0    X  2.0    cm minID: 63E-LN3
Red Bird Mine, Pershing County, Nevada, USA  (see the description of this locality on MINDAT). (This locality is not on your list of areas of interest, but it is a significant locality of interest for its history of production of Mercury-bearing minerals in the western USA.) HgS-11  A very rich vein of bright red crystalline and massive Cinnabar coats approximately 40% of the surface of the matrix.  A portion of the Cinnabar is coated with micro, drusy Quartz crystals.  Microscopic red Cinnabar spheroids are present, along with micro Cinnabar crystals, deposited upon the surface of the drusy Quartz.  Tiny droplets of native Mercury are present in two areas on the front of the specimen. Specimen size: 9.0     X 5.5     X  2.2   cm minID: LTH-XTY	Red Bird Mine, Pershing County, Nevada, USA  (see the description of this locality on MINDAT). (This locality is not on your list of areas of interest, but it is a significant locality of interest for its history of production of Mercury-bearing minerals in the western USA.) HgS-12  Dark red massive Cinnabar coats much of the top of the specimen.  A white massive mineral, present in small blebs on the top and base of the specimen, may be Calomel but its presence has not been verified by analysis.  A small veinlet of bright red Cinnabar cleavages, 1.0 cm in length, is on the back of the specimen.  Small amounts of crystallized Stibnite are present on the base of the specimen.  Another possible associate is small amounts of light tan-brown color massive Oxyplumboroméite, but its presence has not been verified by analysis. Specimen size: 6.0      X   3.5   X  2.3   cm minID: C5K-KJ6	Culver-Baer Mine, near Cloverdale, Mayacmas Mining District, Sonoma County, California, USA (see the description of this locality on MINDAT, and the previous field trip information  sent you by email). (This locality is not on your list of areas of interest, but it is a significant locality of interest for its history of production of Mercury-bearing minerals in California.) HgS-13  Rich amounts of bright red radiating sprays of needle-like crystallized Cinnabar are scattered across the surface of the matrix, associated with drusy Quartz. Specimen size:  7.0    X 4 .5    X 3.0     cm minID: 2HM-7UE
