{"product_id":"oreas-240c","title":"OREAS 240c","description":"\u003cdiv class=\"product-description\"\u003e\u003cp\u003eOREAS 240c is a mid-grade gold certified reference material produced from a \u003cbr\u003e\r\nblend of gold-bearing ore from the Frogs Leg district and a large proportion of \u003cbr\u003e\r\nbarren greenstone host rock. The Frogs Leg ore components originate from Frogs \u003cbr\u003e\r\nLeg Gold Mine, located west of Kalgoorlie in the Eastern Goldfields Province of \u003cbr\u003e\r\nWestern Australia. The deposit comprises steeply dipping, laminated \u003cbr\u003e\r\nquartz-sulphide veins and breccia zones occurring along sheared volcanic–basalt \u003cbr\u003e\r\ncontacts. Mineralisation is characterised by native gold associated with pyrite, \u003cbr\u003e\r\npyrrhotite, and accessory chalcopyrite. The barren fraction consists of finely \u003cbr\u003e\r\nmilled Cambrian greenstone, providing a stable and compositionally compatible \u003cbr\u003e\r\nmatrix for mid-range Au grades.\u003cbr\u003e\r\nOREAS 240c has been characterized using the following methods:\u003cbr\u003e\r\n\u003cbr\u003e\r\n  Gold by Pb collection fire assay (25-50g charge weight) with AAS and \u003cbr\u003e\r\n  ICP-OES finish \u003cbr\u003e\r\n  Gold by Bi collection fire assay (30 g charge weight) with AAS finish \u003cbr\u003e\r\n  Gold by PhotonAssay™ \u003cbr\u003e\r\n  Gold by 15-50g aqua regia digestion with ICP-MS and AAS finish \u003cbr\u003e\r\n  Gold by cyanide leach (20-200g) with AAS or ICP-MS finish \u003cbr\u003e\r\n  Full ICP-OES and ICP-MS elemental suites by 4-acid (HNO3-HF-HClO4-HCl) \u003cbr\u003e\r\n  digestion \u003cbr\u003e\r\n  Full ICP-OES and ICP-MS elemental suites by aqua regia digestion\u003cbr\u003e\r\nCertified values for applicable analytes are operationally defined for each \u003cbr\u003e\r\nmethod, with results under OREAS ISO 17034 scope of \u003cbr\u003e\r\naccreditation.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"product-specs\"\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eState:\u003c\/strong\u003e primary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatrix:\u003c\/strong\u003e greenstone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineralisation:\u003c\/strong\u003e orogenic lode gold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCRM Group:\u003c\/strong\u003e Au \u0026gt;1 ppm, Au only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"certified-values\"\u003e\n\u003ch3\u003eCertified Values\u003c\/h3\u003e\n\u003ctable class=\"analyte-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eAnalyte\u003c\/th\u003e\n\u003cth\u003eCertified Value\u003c\/th\u003e\n\u003cth\u003e1SD\u003c\/th\u003e\n\u003cth\u003e95% CL Low\u003c\/th\u003e\n\u003cth\u003e95% CL High\u003c\/th\u003e\n\u003cth\u003eMethod\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\n\u003ctd\u003eAu, Gold (ppm)\u003c\/td\u003e\n\u003ctd\u003e5.65\u003c\/td\u003e\n\u003ctd\u003eTBD\u003c\/td\u003e\n\u003ctd\u003eTBD\u003c\/td\u003e\n\u003ctd\u003eTBD\u003c\/td\u003e\n\u003ctd\u003ePb Fire Assay\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"OREAS","offers":[{"title":"Default Title","offer_id":44747960254600,"sku":"240c","price":0.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/oceanrmc.com\/ar\/products\/oreas-240c","provider":"Ocean RMC","version":"1.0","type":"link"}
