Adapun untuk rencana kegiatan eksplorasi As for the IM exploration activity plan in 2024, in IM tahun 2024, sehubungan dengan rencana connection with the mining optimization plan at pengoptimalan penambangan pada pit utama the Indomining main pit to a depth of RL-175 Indomining hingga kedalaman RL-175 meter meters according to the Mine Plan target for pit sesuai target Mine Plan untuk pit AB dan AB and in order to optimize the mineable dalam rangka mengoptimalkan mineable reserve potential seams, where several reserve seam-seam potensial, dimana potential seams in pit area still needs to be beberapa seam-seam potensial di dalam known continuity up to the lower limit (down dip) area pit masih perlu diketahui kemenerusan of the pit plan and lateral continuity, the hingga sampai batas bawah (down dip) dari company intends to conduct infill drilling rencana pit dan kemenerusan lateral, maka activities to increase the accuracy of drilling perusahaan bermaksud mengadakan data in the pit area to the lower limit of the pit kegiatan pemboran infill untuk menambah plan where some potential seams from roof & akurasi data pemboran pada area pit hingga floor data indicated that there was thinning or batas bawah rencana pit dimana beberapa pinch out laterally and/or down dip. seam potensial dari data roof & floor terindikasi ada yang mengalami penipisan atau pinchout secara lateral dan atau down dip. Sedangkan, tujuan dari kegiatan pemboran Meanwhile, the purpose of the infill drilling infill adalah untuk menambah keyakinan activity is to increase the confidence of the batas penyebaran lateral dari seam-seam lateral spreading limit of potential seams that potensial yang mengalami pinchout, has been pinch out, increase confidence in menambah keyakinan kemenerusan serta continuity and determine the thickness of the mengetahui ketebalan lapisan kearah layer towards the down dip which is indicated to downdip yang terindikasi mengalami be thinning to the planned lower pit limit, and penipisan hingga rencana batas bawah pit, maximize the mineable reserve of potential serta memaksimalkan mineable reserve seams, and validate the update of the Geology seam-seam potensial, dan mem-validasi model from the update of adding infill drilling update model Geologi dari pembaruan data. penambahan data pemboran infill. Pemboran infill pada area pit AB Infill drilling in the pit AB area is planned to be direncanakan dilakukan sebanyak 10 titik bor carried out as many 10 boreholes with a dengan kedalaman lubang pemboran maximum drilling hole depth of 100 meters with maksimal 100 meter dengan total meter yang a total required meter of 1000 meters. The work diperlukan adalah sebanyak 1000 meter. is planned to be carried out using a minimum of Pekerjaan tersebut rencananya akan 2 units of Jacro 300 rigs or the like. This infill dikerjakan dengan menggunakan minimal 2- drilling project will be carried out using the unit rig tipe Jacro 300 atau yang sejenis. vertical touch coring drilling method and Proyek pemboran infill ini akan dilakukan equipped with geophysical logging up to the dengan menggunakan metode pemboran drilling depth target. touch coring vertikal dan dilengkapi dengan geophysical logging sampai dengan target kedalaman pemboran.
