Orbite Provides Update on HPA Construction

MONTREAL, QUEBEC--(Marketwired - Dec 12, 2014) - Orbite Aluminae Inc. (ORT.TO)(EORBF) ("Orbite" or the "Company") today provided an update on the construction of its high purity alumina plant.

Refractory Material and Project Update

Orbite had announced on October 29th that, following quality control testing by the Company's Technology Development Centre (TDC), product non conformities had been identified with some of the refractory materials supplied by Outotec which could have led to mechanical integrity problems during operations. Specifically, the non-conformities were found in the mortar and the castables supplied.

Orbite then identified and tested replacement materials that could be used to replace the brick and mortar inner lining of the decomposer and calcinator (castable monolith), with no detrimental impact on product quality.

Orbite reported on December 4th, following extensive testing of refractory materials at the Company's TDC that the brick and mortar refractory approach had been selected, instead of a castable monolith for the inner lining of its decomposer and calcinator.

The initially supplied non-conforming mortar will be replaced with a new mortar formulation, sourced from Outotec, anticipated to arrive in Canada in December, as planned. The non-conforming castable material will not be replaced by an Outotec product, but by the alternative proprietary material, sourced from a third party supplier, and tested and approved by Orbite's TDC.

Some of the components of this new castable are sourced from a European manufacturer. Orbite has been informed by its supplier that, contrary to earlier communicated timelines, the components from Europe will not be available until the end of February 2015, leading to commencement of refractory system installation at the end of March 2015.

Consequently, the commencement of commercial production at the HPA facility has been deferred by one quarter to Q3 2015.

Orbite has received and is presently evaluating refractory installation bids from 3 specialized contractors, and expects to award the contract shortly.

HPA Project Budget

Orbite had originally estimated project costs at $31.0M (see June 2013 release), based upon cost estimates prepared by 2 external engineering firms, to complete the plant construction work undertaken in 2012, based on the then contemplated plant design. This estimate was subsequently scaled back to $28.5M after excluding some of the construction work related to the front end (extraction section) of the HPA plant.

The engineering review, conducted throughout 2014, has shown that the original design of the 2012 HPA plant was inadequate to deliver at 3tpd capacity. Consequently, the facility was materially redesigned, and certain installed equipment and piping will be replaced to meet capacity and longevity specifications.
