The Institute of Mine Surveyors of South Africa (IMSSA) Free State branch held their branch meeting at the Afgen offices in Kyalami on 30 May 2014. Branch secretary Ebrahim Ramzan welcomed the 50 mine surveyors in attendance and provided delegates with feedback from the IMSSA council.

Ramzan advised the delegates that the South African Code for the Reporting of Oil and Gas Resources  (SAMOG Code) has been published on the Johannesburg Stock Exchange website  and that a call for comments has been issued. He also reported that the Director of General Mine Survey is handling the matter of the late marking of MSCC papers and will be visiting the provinces to identify and resolve the problem.

The secretary informed the group that the IMSSA President’s Cup Golf Day, held at Randfontein Golf Course, was a great success.  The event made a profit of R17 000 and 114 people participated in the golfing day. Ramzan also advised the delegates that the AfricaGEO conference will be taking place in Cape Town from 1 to 3 July 2014, and encouraged the mine surveyors present to participate in and attend the event.

Ramzan further advised the meeting that the IMSSA Free State branch needed to elect a new member to the branch committee. Mpho Tolo was nominated to take up the vacancy and graciously accepted the nomination.

Following this, Monica Tetteh from the University of the Witwatersrand gave an interesting presentation entitled “Mine Call Factor issues at Iduapriem Mine: Working toward an ore and metal accounting protocol”. She gave an overview of the Iduapriem Mine in Ghana, explained the theory of Mine Call Factor (MCF), and provided details on the fundamentals of ore accounting at the mine as well as its mine-to-mill reconciliation strategy. Tetteh outlined the MCF investigation process and warned against rushing to change protocols saying that this should only be done as part of a managed process. She also explained that an MCF investigation is an ideal platform for misunderstanding and conflict, and emphasised the need to track the ore. In line with this, she recommended that ore and waste resources to the plant should be tracked using reliable passive RFID tags.

The next presentation was given by Charl Retief from Esri South Africa who spoke on the topic of ArcGIS for Mining. Retief started off by providing an overview of geospatial principals for mining and outlined how GIS software can bring value to mining operations. He explained that GIS can be used to plan more efficiently and to execute more effectively. He emphasised the need for mine departments to move away from the prevalent  silo mindset and  to start standardising the collection and sharing of information.  Retief said that mining is inherently geographic and that sharing data and supporting collaboration between departments will lead to new insights and opportunities that will facilitate improved decision-making and planning.

The day ended with vendor presentations from Afgen  and Reef Business Systems, sponsors of the branch meeting, following which delegates then made their way to an enjoyable session of go-karting.
