Month: December 2018

Horizonte Minerals Plc, (AIM/TSX: HZM) (‘Horizonte’ or ‘the Company’) the nickel development company focused in Brazil, is pleased to announce that it has filed the Feasibility Study (‘FS’ or the ‘Study’) for the Araguaia Ferronickel Project (‘Araguaia’, or ‘the Project’) in Brazil’s Pará State on SEDAR.  The Study has been prepared in accordance with the National Instrument 43-101 – standards of Disclosure for Mineral Projects (‘NI 43-101’) and was previously announced on the 29^th October 2018.

The Study confirms Araguaia as a Tier 1 project with a large high-grade scalable resource, a long mine life and a low-cost source of ferronickel for the stainless-steel industry. The Stage 1 FS design allows for future construction of a second Rotary Kiln Electric Furnace (‘RKEF’) process line (‘Stage 2 expansion’ or ‘Stage 2’), with potential to double Araguaia’s production capacity from 14,500 tonnes per annum (‘t/a’) nickel up to 29,000 t/a nickel. The results of this Stage 2 expansion study are included as an opportunity in Section 25 of the NI 43-101 Technical Report with the economics highlighted below.

Stage 1 – FS Highlights:

·     Initial 28-year mine life generates cash flows after taxation of US$1.6 billion with sufficient mineral resources to extend beyond 28 years;

·     Estimated post-tax Net Present Value[1] (‘NPV’) of US$401 million[2] and Internal Rate of Return (‘IRR’) of 20.1% using the base case nickel price forecast of US$14,000 per tonne³ (‘/t’);

·     Upon development, the Project is expected to produce an average of 14,500 tonnes of nickel contained within approximately 52,000 tonnes ferronickel per annum, utilising the proven RKEF technology currently used at over 40 mines around the world;

·     The base case FS economics assume a flat nickel price of US$14,000/t for the entire 28-year mine life based on Wood Mackenzie’s short-term forecast;

·     C1 (Brook Hunt) cash cost year 1 to year 10 of US$3.08 per pound (‘/lb’) of nickel (US$6,794/t), making Araguaia a low-cost producer;

·     Using the consensus mid-term nickel price of US$16,800/t, the post-tax NPV increases to US$740 million with an IRR of 28.1%, reflecting the significant leverage that the Project returns have to any future increase in nickel prices; and

·     Capital cost estimate of US$443 million (AACE class 3), including US$65.3 million of contingencies equating to 17.2% of total capex budget.

Stage 2 – Second Line Expansion Highlights:

A key part of the FS Stage 1 Project design was that the RKEF plant and associated infrastructure was designed to accommodate the addition of a second RKEF process line (Stage 2 expansion), with potential to double Araguaia’s production capacity from 14,500 t/a nickel up to 29,000 t/a nickel. The Project Mineral Resource inventory has the grade and scale to support the increase in plant throughput from 900 kt/pa (Stage 1) to the Stage 2 rate of 1.8 Mt/a supporting the twin line RKEF flow sheet. The Stage 2 expansion assumes operating at Stage 1 production rate of 900 kt/pa for three years, after which free cash flows would be reinvested to expand the plant to 1.8 Mt/pa by the addition of a second line. All figures below represent this combined production of stage 1 for 3 years followed by the enlarged production for the remainder of the Life of Mine. 

·     The Stage 2 expansion, assumed in year 3, supports a 26-year mine life generating cash flows after taxation of US$2.6 billion;

·     No increase in upfront capital cost which remains at the same level at the FS Stage 1 of US$443 million, the Stage 2 expansion is financed through operational cash flow;

·     Estimated post-tax Net Present Value[3] (‘NPV’) of US$741 million[4] and Internal Rate of Return (‘IRR’) of 23.8% using the base case nickel price forecast of US$14,000/t[5];

·     Using a nickel price of US$11,000/t generates cash flows after taxation and payback of capital of US$1.0 billion;

·     Nickel grade of 1.82% for the first 10 years of the Stage 2 operation;

·     Annual nickel production of 29,000 t/a;

·     C1 (Brook Hunt) cash cost year 1 to Year 10 of US$3.00 per pound (‘/lb’) of nickel (US$6,613/t), making Araguaia a low-cost producer. Life of mine C1 cash cost of US$3.51 per pound (‘/lb’) of nickel (US$7,737/t); and

·     Using the consensus mid-term nickel price of US$16,800/t, the post-tax NPV₈ for the Stage 2 option increases to US$1,264 million with an IRR of 31.8%.

Horizonte CEO, Jeremy Martin, commented; 

“Following on from the successful completion of the Feasibility Study for the Araguaia ferronickel project, we are very pleased to file the 43-101 Feasibility Technical Report which includes as an opportunity the Stage 2 expansion to add a second RKEF line to the Project. The Stage 2 expansion would potentially increase annual nickel production from 14,500 tonnes per annum to 29,000 tonnes per annum whilst demonstrating economies of scale for both operating and capital costs.  For this scenario the upfront pre-production capital cost remains unchanged at US$443 million and the incremental capital expenditure to build the stage 2 expansion, is anticipated to be financed out of operational free cash flow. The FS design of the RKEF plant and all associated infrastructure was configured to allow a second RKEF line to be added at a future time, as such the Stage 2 expansion benefits from the existing utilities and infrastructure expenditure. Significant items such as the powerline, water pipeline, overall process plant site, utilities, and slag storage facility already have sufficient capacity built in during the Stage 1 planning to meet the desired production increase.

The economics of the Stage 2 expansion in year 3 are compelling with the Base Case NPV₈ of US$741 million and IRR of 23.8%, increasing to an IRR of 31.8% when applying consensus nickel price assuming no change in the upfront capital investment for the Stage 1 single line RKEF plant as shown in the FS.  If we apply a nickel price of US$11,000 per tonne nickel, the enlarged twin line plant generates cash flows after taxation and pay back of capital of US$1.0 billion.

We have always maintained that Araguaia has a high grade scalable mineral resource with only a small part utilised for the single line plant.  As demonstrated in the Stage 2 expansion the resource can comfortably support the increased capacity for over 26 years with the first 10 years averaging 1.82% nickel which places Araguaia on the upper range of the global grade curve even with the increased mining rate. 

The recent weakness in nickel prices appears to be reflection of macroeconomics and does not appear to have impacted wider consensus of the positive future potential of the nickel market. Demand versus supply deficits remain forecast for the short term. Inventories on the LME continue to fall with significant new supply required for the stainless-steel market which is growing at 5%[6] year on year, with new demand driven from the EV battery sector. Araguaia is anticipated to come online in 2021 and be placed in the lower quartile[7] on the laterite C1 cost curve (year 1 to year 10 of US$3.08 per pound of nickel (US$6,794/t)[8] making it one of the lower cost new nickel projects. Meanwhile the forward C1 cost curve is expected to consistently rise due to the rising costs of inputs as well as the reducing global grade profile across existing mines.

The successful completion of the Feasibility Study and the positive economics from the Stage 2 expansion all confirm that Araguaia is a tier 1 asset demonstrating flexibility and scalability with compelling economics.

The Company is well funded as we work to advance Araguaia to the construction stage and start to advance our second 100% owned Vermelho Nickel Cobalt project as part of the company’s strategy to become a leading nickel development Company. I look forward to updating the market on progress as we move into 2019.”

Stage 2 Second Line Expansion Details:

The FS plant ore feed rate of 900kt/a is based on a single line RKEF plant (Stage 1). This size plant represents the optimal capacity for an achievable capital cost for project financing for a single project junior development company. However, the Stage 1 plant capacity underutilises the significant Mineral Resource that HZM has within the project area (~119Mt Measured and Indicated Mineral Resources at 1.27% Ni).  In the FS, the cut-off grade is 1.4% Ni and represents a “high-grade” option. The marginal cut-off grade for the Project is closer to 1.0% Ni. This means that there is a significant quantity of potentially economic material that is not mined or processed in the current Stage 1 FS schedule. Accordingly, the opportunity contemplated here is that the Stage 1 production scenario (the FS Base Case) is built and produces at an initial production level 14,500 t/a of Nickel, and that the Stage 2, expansion in year 3 is implemented as the project starts generating cash flows, thereby increasing total production to 29,000 t/a Nickel.

To explore the potential value of increasing the production rate at Araguaia, a Stage 2 expansion to 1,800kt/a plant feed in Year 3 was contemplated at a scoping level. In this Stage 2 scenario, Snowden completed pit optimisations based on the FS costs and modifying factors. The pit optimisations targeted any material determined to be economic, rather than the elevated Ni cut-off grade applied in the FS. Only Measured and Indicated Mineral Resources were considered in this scenario. Overall, the target was to achieve a similar mine life to the FS schedule (~28 years). This was achieved by selecting a revenue factor pit shell equivalent to a nickel price of US$11,200/t Ni which yields 44.0Mt of ore feed.

The Stage 1 FS plant layout was designed to allow for the future construction of a second RKEF line.  A significant portion of the Stage 1 RKEF plant and associated infrastructure has sufficient capacity to support the Stage 2 expansion, resulting in substantially lower capital costs to implement the second RKEF line. The Stage 1 equipment and infrastructure that does not require upgrading for Stage 2 includes;

·     The main power line to the plant;

·     The principle road and bridge infrastructure in-bound and outbound to the mine site;

·     Overall plant site layout, plant road / offices / stores / workshops;

·     Refinery facility;

·     The slag storage facility; and

·     Water abstraction pipeline.

As part of the preparation of the Stage 2 expansion, HZM has completed a scoping level estimate of the costs associated with implementing a second RKEF line after Year 3 of the mine life using the FS capex as a basis and locating the additional equipment in the areas within the existing FS plant layout. A summary of the estimated direct equipment costs along with associated civil works and installation costs for the Stage 2 expansion are shown in Table 1.

Table 1  Stage 1 and Stage 2 capex

The additional costs for the Stage 2 – Second RKEF line shown in Table 1 above, represent sustaining capital expenditure which would be financed once the Stage 1 operation is cash flow positive. Therefore, the pre-production capital costs would remain the same as the FS at US$443.1 million.

Key additional items required within the plant area for Phase 2 are included in Table 1; ore preparation dryer, kiln and furnace. Items outside of the plant area include additional pumping capacity for the water abstraction pipeline, a second plant cooling water pipeline and an increase in the cooling water dam capacity.

The operating costs after the Stage 2 RKEF line becomes fully operational were estimated based on the FS operating cost estimate.  A comparison of the physicals and the economics of the FS and the expansion opportunity are shown Table 2 below.
