Mining Stock News; Dia Bras (TSX V:DIB) Provides Third Update on Construction Progress at its Piedras Verdes Mill, Bolivar Property

TORONTO, ONTARIO--( mining stocks newswire  - May 11, 2011) -Dia Bras Exploration Inc. (TSX VENTURE:DIB) ("Dia Bras" or the "Company") is pleased to report that construction of its new, 1,000 tpd Piedras Verdes Mill at the Bolivar Property in Chihuahua, Mexico, continues to progress on time and under budget. The new mill is 80% complete and commissioning is expected in late June 2011.
"We eagerly await commissioning our new Piedras Verdes Mill," stated Daniel Tellechea, President and CEO. "Our operational staff has worked diligently to keep the construction of the new mill and water reservoir on schedule and on budget. Operation of the Piedras Verdes Mill will significantly reduce the cash cost of production, as well as increase the life of the mine, as we will be able to mine lower grade material."
Piedras Verdes Mill
The new Piedras Verdes Mill will process mineralized rock mined from the Bolivar (Alta Ley), IncreĆ­ble, Narizona and El Gallo mines. The latter three mines are being developed so that they will begin production at the same time the Piedras Verdes Mill is commissioned. The Company expects that total operating costs will be decreased significantly, as a result of higher mining and milling rates and the greatly reduced transportation costs for shipping of ore.
The Company is installing the first of two Dominion 9'6" x 14' ball mills, which arrived at the plant site on April 18. This single ball mill will process rock at an initial capacity of 500 tpd but will be ramped up to 1,000 tpd by year's end. The second ball mill will be installed during October 2011 and will raise the mill's capacity to about 2,000 tpd in 2012. Other equipment continues to arrive, such as flotation cells, pumps and other ancillary equipment.
•Transportation of the ball mill required two days of transportation from the Company's Malpaso Mill, due to its size relative to the access roads, as shown below and in the attached photo
•Construction of the flotation circuits is well advanced, as shown below and in the attached photo
•Other circuits, such as the fine ore bins and their discharge tunnels, are well advanced, as shown below and in the attached photo
•The tailings dam is nearing completion, as shown below and in the attached photo
•Development of the site for shops, warehouses and offices has started, as seen below and in the attached photo,%20warehouse%20and%20offices%20at%20new%20PV%20Mill.png.
•The new Piedras Verdes water reservoir is 70% complete and is scheduled to be finished in late May, in time to store rainwater that is expected when the rainy season begins in late May – early June. The reservoir site is shown below and in the attached photo
Commissioning of the Piedras Verdes Mill is a major milestone for Dia Bras. Operation of this new mill will move the Company from small-scale pilot-mining of the Bolivar Project to a significant producer of copper and zinc with by-products of silver and gold. Exploration and development work, plus pilot-mining conducted by the Company since 2005, has demonstrated that the Bolivar Project hosts abundant mineralization in several deposits, all of which will contribute feed to the new Piedras Verdes Mill.
