Geology update on December 10 - IPM PT FREEPORT INDONESIA WEB GIS AND DATA INTEGRATION SYSTEM IMPLEMENTATION Harman Setyadi Mine Engineering Dept, Bandung Institute of Technology ASIA GEOSPATIAL FORUM, 17-19 October 2011, JAKARTA

INTRODUCTION The total ore reserve in 2007 is 2.81 billion mT Grasberg Au-Cu Mine Highlight model update for March 2011 IPM : In March 2011 IPM uses : Using new estimate grade Geology Model Update for : Clay altered limestone at OHS3 HSZ on sector 340 – 20 degree ( will be discussed on the following slides). Mill material type use previous Mar 2010 model. DSTK criteria no changes based on vein density and anhy content Problematic material . D sericite ore is wider than previous model based XRD data. RQD and geotechnical model using August and November 2010 data The total ore reserve in 2007 is 2.81 billion mT 1.04% Cu, 0.90ppm Au and 4.16 ppm Ag Daily production: ~250 Kton/day ore

GIS for Exploration Work Conversion paper work format to digital format Paper  ACAD  GIS format Issues : map versioning, accuracy Conversion spreadsheet to the Database Paper, spreadsheet  MS Access  In-house SQL Database (Geobase) Commercial Database Issues: duplicate sample, incomplete sample information, mismatch information, various format data Requirement: data validation during data conversion and data entry. Geochemical & Geophysical Data processing Sample Co-ordinates correction Generate new images of geochemical & Geophysical information. GIS compilation for Mineral Occurrence Evaluation Training for all geologists, Assign GIS specialist from existing geologist Issues : Change Management Process, lack of computer skill  resistant to change

Objectives Integrated GIS To improve our ability to provide data, maps and reports for compliance purposes in a timely manner. Establish geosciences central information repository through common solution platform Improve governance, audit ability, and transparency of geosciences information management, process, and system Consolidate GIS system desktop licenses Implement clear accountability matrix for geosciences information management

Option 1: Do Nothing Pros Cons No additional cost and effort Not required network infrastructure Cons Every users may have different data version No standardized data format. Inconsistent data quality Data storage redundancy Not clear responsibility Limited GIS ability/ functionality. Less of Information dissemination

Option 2: Develop Integrated GIS Pros Align to FCX Global GIS strategy Standardized GIS data (maps, images, reports) Reduce Data Redundancy Reduce time for data finding and compilation Improve data validation, especially for routine data Allow to improve comprehensive data interpretation Improve accessibility Reduce maintenance and License cost. Cons Require more procedures. Required competent QA/QC resources. Required initial investment (US $ 118,500).

Civil Geotech – Hazard Monitoring

The concept of proposed Web GIS Integration

Grasberg Prism Monitoring

Grasberg Prism Monitoring

Grasberg Prism Monitoring

Status Update The first stage of Web GIS and Data Integration was competed, which is cover the prototype of the system implementation. The second stage for detail and live data connection to the monitoring devices for: Civil Geotechnical Geo Hazard, 75% completed Grasberg Geo Hazard & Prism monitoring, 50% completed Underground Geo Hazard monitoring, 25% completed.

Our Goals Our Data is increase rapidly, to understanding of the meaning of data and the maintaining data in the high quality standard is critical, Data should be : Assessable, Clean and ready to use Integrated geo-science data relationship, Optimizing of the data use, getting the information and make better decision.

Conclusion GIS is only one of tool to make data visualization. web GIS in the integrated system using automatic data replication/ update will give more benefits: reduce man power, accelerate the routine process and make standard report format. Integrated database is not only valuable for web GIS but also for other third parties visualization software and/or reporting system Although this project is not totally completed, we consider that this project will give more benefit to the company. We going forward for continue improvement of the system and idea.
