Lead­ing the way with in­no­va­tive so­lu­tions

The Australian Mining Review - - AUS TIN MINING -

JEMROK has quickly become a leader in un­der­ground and civil min­ing projects and is proud to be as­sist­ing Aus Tin with its ex­pan­sion at its Granville project.

Built on a strong foun­da­tion of work­ing with in­tegrity, in­tel­li­gent and re­spon­si­ble en­gi­neer­ing prac­tices, the na­tional com­pany of­fers an ex­ten­sive range of mod­ern sur­face and un­der­ground equip­ment.

It is also a highly re­spected multi- spe­cial­ist min­ing provider, with ex­per­tise in mine de­vel­op­ment and re­ha­bil­i­ta­tion, ve­hi­cle and heavy equip­ment main­te­nance, light and heavy auto parts pro­cure­ment, mine pro­duc­tion ac­tiv­i­ties, and pro­fes­sional labour hire.

“Jemrok is part of the Kyda Group and cur­rently have five op­er­a­tional sites through­out Tas­ma­nia, NSW and Vic­to­ria, along with min­ing and civil ser­vices Jemrok fa­cil­i­ties in­clude au­to­mo­tive work­shops for main­te­nance and re­pair of ser­vice fleet and cus­tomer ve­hi­cles heavy equip­ment and labour hire,” the com­pany stated.

“While based from our op­er­a­tional sites, our civil en­gi­neer­ing and min­ing teams travel Aus­tralia wide, and we are ded­i­cated to pro­vid­ing the high­est pos­si­ble level of ser­vice and cus­tomer sat­is­fac­tion.”

Mt Cobalt

Drilling and sub­stan­tial 3D mod­el­ling work has also been un­der­taken at Aus Tin’s Mt Cobalt cop­per-cobalt-nickel project in QLD.

“We’ve re­ceived some very good drilling re­sults in Jan­uary this year from Mt Cobalt with re­sults of up to 28 me­tres at 0.3 per cent cobalt,” Mr Williams said.

“More re­cently 3D mod­el­ling of mag­netic data gen­er­ated three dis­crete tar­gets with el­e­vated mag­netic sus­cep­ti­bil­i­ties of 0.2 SI and 0.129 SI iso-layer units were iden­ti­fied, the largest ly­ing ap­prox­i­mately 600m be­low Mt Cobalt.

“Based on col­lec­tive work to date, the zone of 0.2 SI mag­netic sus­cep­ti­bil­ity may rep­re­sent the sul­phide source for cobalt and nickel min­er­al­i­sa­tion at Mt Cobalt.

“None of the tar­gets have been validly tested by pre­vi­ous drilling and the Com­pany is de­vel­op­ing a pro­gram to drill test the tar­get zones with a pro­gram of three holes up to 650m in depth.”

A ge­o­log­i­cal com­par­i­son between Mt Cobalt and Glen­core’s Ko­ni­ambo nickel and cobalt re­source in New Cale­do­nia pro­vides some direc­tion for fu­ture ex­plo­ration, sup­ported by re­cent field work at Aus Tin’s Jack­son North.

Both Mt Cobalt and Ko­ni­ambo are “un­usual and al­most unique” in that they were de­posited in two episodes, firstly by hy­draulic frac­tur­ing and mix­ing of me­te­oric wa­ters, fol­lowed an in­de­ter­mi­nate time later by su­per­gene en­rich­ment.

Both de­posits also ex­hibit veins of dis­tinc­tive red-brown, mi­cro crys­talline hy­dro­ther­mal quartz brec­cia, which has un­der­gone frac­tur­ing and re­seal­ing above the ser­pen­ti­nite.

Aus Tin said dis­cus­sions were un­der­way with drilling con­trac­tors, and it re­mained hope­ful that pend­ing all reg­u­la­tory ap­provals, the next drilling pro­gram will com­mence dur­ing the Septem­ber quar­ter.


For the next three years, Mr Williams said Aus Tin plans to de­liver sus­tain­able tin and cobalt tar­get­ing low cap­i­tal and low oper­at­ing cost projects in Aus­tralia.

Aus Tin said a new $2.5 mil­lion fund­ing pack­age would help drive de­vel­op­ment across Granville, Taronga and Mt Cobalt.

“Dur­ing the [June] quar­ter, share­hold­ers rat­i­fied a new $2.5M, 24-month con­vert­ible se­cu­rity with the Lind Part­ners on su­pe­rior terms,” Mr Williams said.

“Fol­low­ing the end of the quar­ter the Com­pany re­ceived the bal­ance of fund­ing and cur­rently holds its high­est level of cash since 2013 when it merged with Taronga Mine Lim­ited.

“Funds will be used will be used to meet ex­plo­ration, de­vel­op­ment and work­ing cap­i­tal costs.”
