According to Sergio A . Trelles , special advisor , the positive results are encouraging us to go on with exploration and evaluation activities .
Historically , mineralised structures have been mined by access made through the La Cascabel , Guadalupe and Sonora Copper adits . There are additional sublevels of adits and stopes yet to be mapped and sampled pending safety evaluations .
UKRAINE : MILLS REDUCE WASTE
Engineering Dobersek in Germany and Severniy Mining and Processing ( SevGOK ) in Ukraine have selected Metso Outotec ’ s mill discharge pumps for Severniy ’ s greenfield process waste thickening plant .
Metso Outotec ’ s reliable high-capacity pumps will be used to pump the iron ore concentrate plant`s waste sludge into the settling ponds from the thickeners . The 22 pumps to be delivered by Metso Outotec include ten large high-capacity MDM700 pumps . Together , the pumps are capable of handling a total volume of 117.500 m 3 of waste sludge per hour .
“ SevGOK ’ s complex is the second of its kind in Ukraine , and Engineering Dobersek in Germany has designed it . With this investment , SevGOK aims to decrease environmental impacts and costs by lowering energy consumption and water usage ,” says Axel Stappen , managing director at Engineering Dobersek .
“ We are delighted to have been selected to supply our MD series pumps to SevGOK ’ s project . To give an idea of the size of an MDM700 pump , it can weigh as much as 31 tons and be 2.8 meters in diameter , and have an impressive pumping volume of up to 9.650 m3 / h . The MDM pumps operate in very demanding conditions , and we ’ ve designed them to operate reliably and to withstand exceptional wear ,” says Michael Nienhaus , head of sales , slurry pumps , Germany , Metso Outotec .
MEXICO : UPDATE ON SONORA
Benjamin Hill Mining has given an update on the Sonora copper vein structure which the company recently mapped over 1 200m in length . Sonora contains values of 9.6 g / t gold , 169 g / t silver , and 4.3 % copper .
The vein structure is mappable over three levels of underground workings and can be traced as a high-angle mineralised body with at least 120m known depth .
The Saguaro vein outcrops over several kilometres including a continuous section up to 3 500m in length with highlight assays of up to 3.5 g / t gold , 72 g / t silver and 1.7 % copper .

Benjamin Hill is currently integrating technical information for the modelling of rock blocks , veins , and historic adits and stopes to develop a safety first mine rehabilitation plan .
The objective is to gain access to yet unassessed sublevels in these historic mines with the goal of underground diamond drilling on the mineralised structures .
AUSTRALIA : JAPAN / BHP IN GREEN MOU
Article first published on Australia Mining news
Australian mining giant BHP has created the Green Electric Vehicle ( EV ) Ecosystem with two major Japanese businesses to supply nickel sulphate for EV batteries from BHP Nickel West in Western Australia .
The memorandum of understanding ( MOU ) between BHP , Prime Planet Energy & Solutions ( PPES ) and Toyota Tsusho Corporation ( TTC ) will see PPES turn the nickel sulphate into lower carbon batteries for EV manufacturers like Toyota .
PPES is a leading Japanese lithium-ion battery manufacturer and will also explore the recycling of battery scrap and used batteries at Nickel West for further processing to reduce waste .
“ Creating a Green EV Ecosystem is something that could make a real difference for the battery supply chain ,” says Vandita Pant , BHP chief commercial officer .
To enhance its downstream sustainability , Nickel West will also work with Toyota Motor Corporation Australia ( TMCA ) on their own EV supply after successful trials in late 2020 . BHP Nickel West asset president Jessica Farrell said this partnership came in response to extreme demand forecast for nickel in the near future .
“ Demand for nickel in batteries is estimated to grow by over 500 % over the next decade to support increasing demand for electric vehicles ,” says Farrell .
In January 2021 , BHP partnered with Toyota to trial light electric vehicles ( LEV ) at Nickel West which saw a Land Cruiser 70 converted from running on diesel to fully electric via onboard battery power .
Toyota and BHP have maintained a strong relationship for the past 20 years . www . africanmining . co . za
