| Swingplane Ventures, Inc. Provides Information on Chile's Rich MineralizationSANTIAGO, CHILE, Jan 28, 2013 (MARKETWIRE via COMTEX) -- Swingplane Ventures, Inc. (OTCBB: SWVI) (the "Company") is pleased to update information on Chile's Rich Mineralization.Chile's well established copper porphyry belt, which hosts world class deposits including CODELCO's giant Chuquicamata deposit which, by excavated volume, is the largest open pit copper mine in the world. For many years it was the mine with the largest annual production in the world, but nevertheless it remains the mine with by far the largest total production of approximately 29 million tonnes of copper to the end of 2007. The La Escondida (BHP Billiton 57.5%, 30% by Rio Tinto) deposit is currently the highest producing copper mine in the world. Its 2007 production of 1.483 million tonnes of copper was worth US $10.12 billion and represented 26% of Chilean copper production, according to the US Geological Survey's preliminary estimates of 2007 world mine output.The Chilean Iron Belt (CIB) is a similarly narrow, north-south oriented belt containing hundreds of magnetite-apatite ("Kiruna-type") and Iron Oxide-Copper-Gold (IOCG) occurrences located outboard (i.e. on the coastal side) of the porphyry belt and extends approximately 600 km from 31 degrees S north to 25 degrees S. The CIB hosts several large IOCG mines, including Candelaria (Freeport McMoran) mine which as of December 31, 2011 reported a resource of 399 million tonnes of copper grading at 0.58% copper and 0.13% gold, recoverable proven and probable reserves. The Mantoverde mine (Anglo American), as well as numerous smaller mines and/or projects, including Santo Domingo (Capstone Mining) mine which highlighted in its pre-feasibility study completed in the third quarter of 2011 average annual production of 144 million pounds of copper, 4.1 million tonnes of iron concentrate and 15 thousand ounces of gold. Additional mines include Relincho (Teck Corp) and Andacollo (Teck Corp (90%) / ENAMI (10%)).Note: The preceding contains grades and tonnages reported by the companies cited. The grades and tonnages cited may not be compliant with NI 43-101. Mantoverde, Santo Domingo and the Punta Del Cobre - Candelaria Belt are considered representative of IOCG-type deposits in similar structural settings both north and south of the Property and, as such, are considered analogues for the style of mineralization on the Property."Manto-type" copper deposits overlap the CIB over a distance of approximately 1100 km, between 33 degrees S to 21 degrees S. In addition, IOCG occurrences have been reported within the "manto-type" belt from just south of Vallenar (29 degrees S) to just south of Chanaral (26 degrees S). These well defined belts are spatially associated with the Atacama Fault, a well developed fault system that extends from Iquique (20 degrees S) north to La Serena (30 degrees S).The Algarrobo Property (the "Property") is interpreted to be an IOCG occurrence located in the southern portion of CIB in the area of overlap with "Manto-type" copper occurrences, consistent with other IOCG occurrences reported in the area. The Property is located on the west margin of the Atacama Fault System and hosted within the Pluton Sierra El Robe, a dioritic to quartz dioritic pluton of Jurassic age.Faulting associated with the Atacama Fault System is believed to be the primary control on mineralization, both in terms of the controlling structures hosting mineralization and the fluid conduits that allowed movement of metal-rich fluids. Copper-rich hematite is the predominant form of mineralization in the oxidized zone near surface, with copper sulphides underlying a variably developed transitional zone below approximately 120 m.Mining operations in the Algarrobo area are comprised of near surface workings to more extensive operations extending several hundred metres below surface. Approximately 35 mines, ranging from near surface excavations to underground mines, have defined, and are centered around, three main mineralized trends, as follows:-- Panga, Ecuador, Urguay, etc. in the north -- Descubridora, Estaca, Viuda, etc. in the center -- Buena Vista, Alicia, etc. in the south The mines developed along these well defined mineralized trends have produced variable quantities of high grade copper, shipped as direct smelting ore to the ENAMI facility at Copiapo, approximately 45 km south of the Property.Further exploration and immediate small scale production is well justified. |
