    1 Executive Summary

    Mining activities and capital works programs continued throughout the quarter, despite significant interruptions in February and March due to adverse weather conditions. The bulk of the waste material was removed in stage 4 of the pit, exposing the remaining high grade and medium grade ore. Mining activities recommenced in March, and it is expected that extraction of all remaining ore material will be completed in late April. Progress continued on site infrastructure during the quarter with the first 32 rooms (stage 1) of the Sherwin camp completed and personnel scheduled to relocate during week 1 of April. All electrical reticulation to all rooms, water and waste water reticulation to/from all rooms, installation of the septic waste system, walkways and decking adjacent to rooms was completed during the quarter. Underground services required in stage 2 (additional 32 rooms) was also completed, with the remaining services in stage 2 scheduled to be completed in Q2. Final works including verandas, walkways and access pathways (between buildings and the mess are also scheduled for completion in Q2.

    Following damage to the main access haul road in February due to flooding, culvert piping was delivered onsite during March in preparation for repairs to the main mine site haul road. A bypass road was built to provide access to site, including access for road trains carting ore, which shall be removed once the main haul road is re-constructed.

    Ore trucking was hampered during the months of February and March due to persistent rain forcing closure of the Roper Highway, delays getting supplies (including fuel and parts onto site) and damage to sections of the mine haul road and Roper Highway due to flooding. Approval to recommence trucking was received from Dept. of Main roads on 16th March, but on a limited capacity due to road repairs being completed and persistent rain causing hazardous road conditions.

    Progress continued on the mine plan and schedule throughout the quarter with additional grade control drilling completed in stage 4 of the pit to close off the wireframe model, and resource drilling commencing in stage 3 of the pit to be used in generating the wireframe model in the next mining area. Delays in recommencing mining activities in stage 4 of the pit resulted in significant changes to the production schedule. Production and transport schedules and the shipping schedule (allocation of Laydays) were constantly being revised during the quarter due to the significant interruptions to the mine production. Work continued on preparation of the short term schedule forms part of the medium term 18 month production schedule (reviewed and revised on a rolling 3 monthly basis) and ultimately the Life of Mine plan. Resources were employed to focus on completion of the Mine Management Plan (MMP), including the many environmental projects to be included in the final submission to be approved by the Department of Mines and Energy.

    Safety remained paramount for the company and efforts continue on the preparation of site safety policies and procedures. Incidents were reported during the quarter which was investigated onsite. The most serious incident involved a road-train on the Roper Highway making contact with a vehicle parked on the side verge of the highway, waiting for the road train convoy to pass. No injuries resulted, but stricter conditions for travel on the Roper Highway have been implemented.

    Subsequent events to the reporting period include:

    All documentation relating to Native Title agreements have been executed by Sherwin and the Native Title holders.

    Additional information has been requested and provided to the EPA.

    The 3rd Shipment has been booked for mid-May.

    2 Environment, Health and Safety

    2.1 Social Responsibility

    This report highlights the outcomes of work undertaken by Sherwin Iron’s indigenous liaison officers during the first quarter of 2014. It has been prepared as part of the company’s wider Social Responsibility reporting requirements.

    2.1.1 Cultural Heritage Management

    Wet season conditions prevented fieldwork from being undertaken during the quarter. Consequently, Cultural Heritage Management focused largely on information management and on preparation for the forthcoming field season.

    The principal activities undertaken included:

    • Integration of data collected from archaeological site investigations during 2013 into Sherwin Iron’s GIS and mine mapping database. This provides a platform through which cultural heritage material can be managed and protected during mine planning and operations.

    • Investigating the feasibility of a real-time reporting system that will allow feedback of information to Traditional Owners through a computer portal based at the mine site.

    • Preparing formal Strategic Plans and Procedures as part of the Company’s manual for management of Cultural Heritage.

    • Planning of archaeological field surveys for the next quarter.

    It is anticipated that archaeological fieldwork will recommence in early May, with surface surveys planned for areas immediately to the north and the south of the existing Bulk Sample Pit. This will allow sampling to continue and a smooth transition to mining to proceed once approval has been obtained.

    Archaeological fieldwork will continue throughout 2014 with completion of additional archaeological surveys at Area C, Mount Scott and other locations determined by exploration and mine planning. Additional projects (such as recording of language and traditional knowledge) will be considered and integrated into the cultural heritage management system as time and resources permit.

    2.1.2 Social Benefits Management

    A suite of social benefit initiatives were prepared as part of the environmental impact assessment process. So far only a limited amount of work has been undertaken, mainly because the additional resources required will only become available once the project has transitioned to its mining phase.

    Sherwin Iron’s main focus during the quarter related to developing its processes for integrating local Aboriginal people into the workforce. Prior to and during March, Sherwin Iron had 3 local Aboriginal people working at the site as laborers. A further 24 applications have also been received from the Northern Land Council on behalf of people from local communities seeking employment. Sherwin is currently reviewing these applications in preparation for proposed expansions of work once the project has been approved.

    The principal activities undertaken during the quarter included:

    • Preparation of a formal Strategic Plan to address Aboriginal employment at the Project.

    • Holding round table discussions with the Northern Land Council and Balmoral Contracting to plan for a larger intake of Aboriginal employees once the mine has been formally approved.

    Employment planning will continue throughout 2014, with the intention to hold meetings with contractors and the NLC every two weeks – monthly at a minimum.

    A small number of short-term and casual employment opportunities are expected to arise once archaeological fieldwork recommences. Additional opportunities for developing Joint Ventures with family groups continue to be investigated.

    2.2 Safety

    Safety remained paramount throughout the month, despite the significant interruptions to the operation, however 3 incidents were reported. The most serious incident involved a road-train on the Roper Highway making contact with a vehicle parked on the side verge of the highway, waiting for the road train convoy to pass. No injuries resulted, but stricter conditions for travel on the Roper Highway have been implemented.

    4 Mining Production

    Mining for the quarter was below expectations due to delays caused by heavy rainfall, particularly during February.

    Mining of Stage 2 was completed in February. Mining of Stage 4, blast 1 was completed in January and mining of blasts 2 – 9 began in March, with the main focus the removal of waste from all blasts. 15,356 tonnes of low-grade ore was mined from Stage 4 in March, primarily from blasts 2, 6 and 7.

    A&M Drilling returned to site in February to recommence blast hole drilling in Stage 4 and to also start charging and loading holes drilled in late 2013. Drilling in Stage 4, blasts 4, 5, 8 and 9 were completed in March. A total of 859 holes (7,223 metres) were drilled for the quarter.

    Other works for the quarter included:

    A total of 24,864 tonnes of waste, road base and rocks were carted to various destinations including the camp haul road and the Sherwin Creek area. This material was used to build a bypass road after the haul road collapsed during heavy rainfall in February.

    Grade control drilling was carried out in stage 4 blast 8 (intensive drilling at closer spacing) and stage 3 (wider spacing). Cheyne Drilling spent 7 days on site to complete this job.

    6 Transport and Shipping

    35,376t of ore was trucked to Mataranka at 57.53% Fe. Significant rainfall during the quarter caused the haul road to close on several occasions. 15 days of haulage were lost during February and March due to damage and flooding of the haul road.

    18,217t of ore was trucked from Mataranka to Darwin at 59.39% Fe. No haulage to Darwin has occurred since 21st January due to heavy rainfall.

    Significant damage was caused to the stockpile pad at the Port during the second shipment due to heavy rain and equipment breaking through the floor of the pad. 70% of the Port stockpile pad is now available for use with further works continuing to repair the remaining 30%. Existing stockpiles have been reconsolidated. The remaining repairs to the pad should be complete at the end of the first week in April.

    The second shipment was a fines ship containing 60,015t at 58.24%. This left the Port in the second half of January.

    7 Projects

    7.1 Exploration

    Approval from the Executive Director has been given for reconnaissance diamond core drilling of key targets at Mt Scott to confirm existence of DSO grade (evident in mapped/rock chipped zones) before committing to a full RC drilling programme. Core drilling is planned to start on 28th April.

    Sherwin Geology group was asked to contribute to groundwater search through a regional structural interpretation from available data in early April.

    Mining Lease application ML 29784, covering proposed DSO Operations, was surveyed by AMM surveys (formerly Vekta) on 25th March in anticipation of the Mining Lease being granted.

    Renewal of the EL 26412 tenement was submitted to the DME with a waiver of reduction, so that Sherwin retains the full tenement area. This tenement hosts targets with DSO grade from extensive rock chip sampling in 2011 and is yet to be drill tested near Western Desert Tenement and WDR resource boundary.

    The Annual Group Technical and Expenditure Report for Roper River Iron Ore Project is being prepared for submission to DME by 27th April. Bulk Sample Extraction has ensured Sherwin has met its Project covenant exploration expenditure of slightly over $1M on its total exploration tenements.

    7.2 Feasibility Study

    7.2.1 Pre-Feasibility Study of DSO Project in Area C

    Continued work on the Pre-Feasibility Study for the DSO Project in Area C has provided information for the EIS (Environmental Impact Study) and EMP (Environmental Management Plan).

    Mine planning work will provide information in April for:

    The Bulk Sample Pit Project

    o Grade control resource block model

    o Production reconciliation model

    o Schedules of mining, crushing, transport, and shipping

    MMP - the final site layout, organisational structure, and manning schedule

    DSO Pit Project – 12 month rolling mine planning

    o Site infrastructure layout and development schedule

    o Compile grade control model and exploration model

    o Detailed stage pit design for 12 month mining plan

    o Construct detailed schedule model for schedule from pit to port

    Mine Production Report System

    o Production database established in March 2014

    Production Reconciliation model

    o Grade control block model constructed

    o Reconciliation model will be developed in April to provide information for EOM report.

    7.3 Status Approval

    7.3.1 Environmental Approvals

    The Supplementary Environmental Impact Statement (SEIS) was finalised and submitted on the 25th March. Additional information can be requested by regulators up until the 15th April. If no additional information is requested, the NT EPA must provide its assessment report to the Minister by the 29th April.

    The NT EPA assessment will then be provided to the Commonwealth for approval under the EPBC Act. This is likely to take the full mandated period, potentially until the 9th June. At that point, Sherwin will also be advised of any additional conditions which may be imposed. Any such conditions must be included in the MMP, which cannot be submitted until after EIS assessment is complete.

    Finalising a draft of Environmental Management Plans, as well as development of an Environmental Management System to comply with ISO140001, is also required before the MMP can be completed and submitted.

    7.3.2 MMP Approval

    A first-draft MMP document will be completed in early April 2014. Extensive input is required from Sherwin, particularly in regard to the final site layout, organisational structure, manning, and a wide range of environmental management commitments.

    The main risk items to timing of MMP completion however, are the identification of adequate groundwater supplies, and completion of the traffic management plan. The traffic MP relies on formalisation of the transport agreement with the NT Government, and knowledge of the exact requirements of this agreement.

    Submission of the MMP is targeted for early June, as soon as the EIS assessment is completed. That primarily relies upon:

    there being no significant extra conditions attached to EIS approval;

    the water search being successful in a timely manner;

    The roads use agreement with the NT Government being finalised, conditions known and a traffic management plan being finalised.

    The MMP assessment time is not mandated, but typically takes around a month. This means MMP approval should be possible by early to mid-July 2014.

    7.3.3 Deposit “C” 3 Mtpa DSO Project Approval Schedule

    The likely approvals timetable is outlined below. Completion of the Mine Management Plan approval process and commencement of mining operations is targeted for early to mid-July 2014.

    This is an ambitious but achievable outcome, which is dependent on optimum outcomes in the many components of work involved, in particular, the search for a water supply. Therefore some risks exist in this target.

    Other components which will also need to be in place include the granting of the ML and associated general purpose leases, and submission of an application for Mining Authorisation (bundled together with the MMP).

    Once the MMP is approved, the various Works Approvals applications can be lodged. These will be required for construction of some project components but are not required for operations using existing infrastructure.
