Sarytogan Graphite Ltd (ASX:SGA) MD Sean Gregory tells Proactive the company has achieved saleable graphite concentrate grade of 81.4% total graphitic carbon (TGC) at 84.4% metal recovery from the latest bulk flotation testing of samples from its Sarytogan Graphite Deposit in central Kazakhstan. The 60 kilograms of composite samples blended from eight diamond drill holes from the northern and central graphite zones at an average head grade of 32.5% TGC were tested in September at the Perth lab of Metallurgy Pty Ltd. Significantly, the metal yield is higher than the 76.6% previously achieved on the same sample at the bench scale, which means that the project has the potential to deliver very low operating costs per tonne of flotation concentrate.
“The results of the bulk concentrate test confirm that saleable graphite concentrate (greater than 80% TGC) can be readily produced from the giant and exceptionally high-grade Sarytogan Graphite Deposit,” Gregory said.
“Allocations of bulk concentrate have now been received by multiple global laboratories.
“Their important downstream test work has already commenced aimed at replicating the previous excellent purification results and importantly, demonstrating spheroidisation and battery performance.”

Sarytogan Graphite Limited is a mining exploration company. The Company's Sarytogan Graphite Project is situated in the Karaganda region of Central Kazakhstan and the exploration concession covers approximately 70 square kilometers (km2). It is located in the industrial mining area and is connected by highway to Karaganda City. The Sarytogan Graphite Project is prospective for graphite. The Sarytogan site is confined to the western and southwestern limbs of the Shiyozek fold, complicated by the large curved Sarytoganbai syncline which trends in northeast and east directions. The west limb of the Sarytoganbai syncline is composed of rhyolite porphyry tuffs and rhyolite porphyry containing interlayers of grit, sandstone, and limestone. The east limb of the Sarytoganbai syncline is characterized by sandstone, shale, siltstone, limestone, and calcareous sandstones that are exposed to the surface. The southwestern part of the site is composed of dark grey carbonaceous siltstones.
