Norasa comprises Valencia and namibplaas in the Erongo Region of Nambia, which is also host to several other key operating uranium mines

Property Description and Location

The Company’s flagship project is Norasa which includes the wholly owned Valencia project (ML 149) which has a 25 year mining licence and a 100% interest in the Namibplaas project (EPL 3638), which is located 4.5 km north east of Valencia. Both projects have NI 43-101 compliant uranium resources and reserves. The properties are located in the Republic of Namibia, located approximately 75 km south-west of the town of Usakos in central-west Namibia and together are known as the Norasa Uranium Project.

Valencia is situated on the farm “Valencia 122”, which is located approximately 75km north-east of the town of Swakopmund in central-west Namibia, covering an area of 735.6 ha and is registered in the name of Valencia Uranium (Pty) Ltd (“Valencia Uranium”). ML 149 was converted from EPL 1496 on June 23, 2008 and is valid for 25 years from date of issue by the Namibian Ministry of Mines and Energy (“MME”) and is renewable.

The entire Valencia mineral licence area is located on privately held farmland. As required by law, an agreement must be entered into between a mineral licence holder and the landowner to allow exploration activities. In order to progress a project to mine development, a compensation agreement is required to offset the effects of the operation. In April 2009, Valencia Uranium entered into a compensation agreement with the owner of the farm Valencia 122, in relation to Section 52 of the Minerals Act of 1992, granting Valencia Uranium unrestricted use of the land on and around ML 149 covering an area of 3,327 hectares. A similar agreement was reached with the owners of the neighboring 594 hectare farm “Bloemhof 109”, located to the south, for the construction of additional infrastructure and for primary access to the Valencia site.

These agreements facilitated planning for the necessary infrastructure required to support mining operations. This infrastructure has been approved by the MME as the operation’s accessory works and includes inter alia the main pit, waste dumps, tailings dump, pipeline, power lines, roads, process plant, explosive magazines, etc. The construction camp / operations village have also been approved. Environmental clearance was obtained for all operations relating to Valencia, although some amendments to the Valencia plan will be required to include the Valencia satellite pit and relocation of some of the mining infrastructure. All amendment issues will be covered in the updated EIA / EMP.

Namibplaas is located 4.5km northeast of the Valencia deposit on the farm “Namibplaas 93” with a total surface area of 1,269 ha. Forsys is actively engaged with the Ministry of Mines and Energy (MME) to renew its Exclusive Prospecting Licence (EPL 3638) for further pit optimization work at the Namibplaas site. This renewal is crucial for gathering the necessary data to secure a full Mining Licence (ML-251 in application) at Namibplaas.

Earlier in the year, Forsys successfully renewed its Environmental Clearance Certificate (ECC) from the Ministry of Environment, Forestry and Tourism This three-year ECC is vital for ensuring compliance with environmental regulations, allowing the Company to advance its development plans for the Norasa project. The ECC renewal process evaluated the Company’s environmental management practices, including waste management, emissions controls, biodiversity protection, and community engagement, among other factors.

The environmental studies for Namibplaas are underway, with baseline monitoring of groundwater, air quality, noise studies, archeology, flora & fauna and soils already completed. This work is being done as part of Norasa and is taking the form of an amendment to the original Valencia EIA/EMP, a process that has been approved by the Ministry of Environment and Tourism.

There are no historical environmental liabilities for either the Valencia or Namibplaas properties.


2015 Definitive Feasibility Study (DFS)

The Company released a Definitive Feasibility Study in March 2015 (“DFS”). A summary of the outcomes of the study are as follows:

  • Mineral Reserves increased from 79.0 Mlbs U3O8 as of October, 2013 to 90.7 Mlbs U3O8 as of February, 2015 (up by 14.8%), due to a 16.4% increase in tonnage and only a slight decrease in the average grade
  • The operating costs per pound are estimated to average $32.96/lb U3O8 over the first 5 years of production and $34.72/lb U3O8 over the life of the mine
  • The economic analysis results in an estimated pre-tax net present value (NPV) at a discount rate of 8% to Forsys of $622.6 million. Using the initial investment and operating cash flows from inception, the pre-tax internal rate of return (IRR) is estimated to be 32%
  • The Norasa plant throughput is 11.2 M/T per annum to produce an average of 5.2m/lbs U3O8 per year

Norasa has received NamWater’s (Namibia’s national bulk water utility) assurance of a supply of water during the construction phase of the project. This will require a 31km temporary pipeline extending from the Rössing reservoir to the construction site. Norasa will design and construct this temporary pipeline with a 300 m3/day capacity required to service the construction camp and for construction activities. This pipeline is to be installed adjacent to the completed access road. Production from Norasa will require construction of a permanent 31km main pipeline (replacing the temporary line used during mine construction) linking Norasa to the Rössing reservoir. The Company is working with NamWater, who is responsible for the tendering and construction of this water pipeline.

Most of the water supply infrastructure will require an upgrade to cater for Norasa and the expansion plans of other operations. Norasa has requested a water allocation of 3 Mm³ annually for its operating requirements.

The nearest power off-take point that can supply Norasa is the Khan substation, located at Ebony, 26km north of the project site. However, the direct route is very rugged through the Khan Valley and tributaries and an alternate indirect transmission route of nearly 30km has been laid out by NamPower. The Khan substation has recently been upgraded and expanded. NamPower met the cost of the new substation although a new bay for Norasa will be at the mine’s expense, as will be the cost of the transmission line to the mine. Power distribution to the mine is planned to be a 220kV transmission line as part of a regional expansion and strengthening of the coastal power supply using the Norasa line as stage one of a ring feed. At an installed capacity of approximately 35MW and a mine draw of about 31MW, two 40 MVA transformers would be installed, one of which would be maintained as a backup unit. It is assumed that the Company would have to carry the cost of establishing the substation.

Standby power generators are being considered by the Company, but a decision on the capacity will be taken at a future date. The generators will be connected to a synchronization and load control panel to operate the generator sets. This control panel will consist of a switchboard arranged for automatic synchronizing of the generator sets, which would include motorized circuit breakers to synchronize the generator sets to a common bus bar. A bus coupler would be included to split or combine the common bus bar to give flexibility to synchronizing or power sharing.

The preferred route to access the mine was determined to be across the Khan River, using tributary valleys. This route links the mine to the B2 highway, 12km northeast of Rössing. The total length of this new road is approximately 26km. Construction of the industrial grade gravel road was completed in mid-2010. Some of the internal service roads were also constructed.


Reserve Estimation Process

The open pit optimisation process to determine a generalised open pit shape (shell) that provides the highest value for a deposit. The process takes into account all revenues and costs and includes mining and processing parameters. It is from this analysis that a shell will be selected as the guide for a practical ultimate pit design

The input parameters for the process included but are not limited to:

  • The latest resource models
  • Modifying factors including mining ore loss and mining dilution for any given block;
  • Updated mining operating costs and mining production parameters;
  • Updated process recovery, processing costs, mining and processing production rates inclusive of respective ramp-ins;
  • Pit slope geotechnical factors;
  • Mill throughput rates and mining rates over time;
  • Uranium price, royalties and discount rate.

The practical pit and pushback designs were based on the optimisation results. The objective of pit design process was to transform the optimal pit shell obtained from the open pit optimisation study into a practical pit with ramps, bench and berm configurations, taking into account design criteria and geotechnical constraints. The practical ultimate pit design was then used to generate a reserve statement in accordance with the National 43-101 reporting criteria.

The table below shows the pit dimensions of the Valencia, Satellite and Namibplaas. The depth was calculated based on an estimated collar 768m,745m and 720m for each pit respectively.
