SMELTING & PURIFICATION

IMP will build a co-located Lead Smelting & Purification Plant and Zinc Smelting & Purification Plant at Modern Cikande Industrial Estate, Banten, one hour drive time from central Jakarta, Indonesia. Based on an extensive Detailed Feasibility Study, IMP has determined the following co-located Lead and Zinc Smelting & Purification Plant specifications:

SPECIFICATIONS

  • Input Capacity Lead Concentrate: Up to 80,000 metric tons per year
  • Input Capacity Zinc Concentrate: Up to 110,000 metric tons per year
  • Output Capacity Lead Ingot: Up to 40,000 metric tons per year
  • Output Capacity Zinc Ingot: Up to 55,000 metric tons per year
  • Land requirement: 12 – 15 hectares
  • Electricity requirement: 40 MW – to be provided by PLN (Indonesia’s national electrical provider)

Build Time: Cold Commissioning November 2021, Hot Commissioning December 2021, the Date of achievement of Commercial Operation (COD) by January 2022.

EPC SELECTION

IMP has selected a proposal from Metallurgical Corporation of China (MCC) to build the plants, whom have provided the following basic design concept. In Q1 – Q2 2020, IMP expects to contract with MCC to do a Front End Engineering Plan so that a more specific plan for review will be completed. This plan will then be reviewed by an independent engineering firm specializing in Zinc and Lead smelting and purification from  January to March 2018. When the analysis is complete, the EPC (Engineering, Procurement and Construction) Agreement will be negotiated and signed around June 2018, the land will be purchased, and the NTP (Notice to Proceed) will be delivered to MCC to commence Detailed Engineering and Construction on a 30 month schedule of completion by December 2021. See Operations Planning for more details.

PLANT DESIGN CONCEPT

This plan requires 12 to 15 hectares of land, which will be contracted and purchased in early 2020 based on an independent review of MCC’s proposal.

PLAN LOCATION CONCEPT

Modern Cikande Industrial Estate, Serang, Banten Province, Java, Indonesia, 45 minutes drive from Jakarta. The primary reason for this choice of location is that PLN has a glut of electricity in the area and is willing to provide 40 MW of electricity directly.
