First Bauxite Completes Bulk Sample Test Pit Programme at Bonasika 7 Bauxite Deposit

First Bauxite Corporation ("First Bauxite" or the "Company") is pleased to announce that it has completed a bulk sample test pit programme at its Bonasika 7 bauxite deposit.

The Company's News Release dated December 8, 2015 provided a general update on the expected use of proceeds from the US$15 million private placement of secured convertible notes to Resource Capital Fund VI LP. This included using a portion of the proceeds to undertake a bulk sample pit programme to confirm mining and processing assumptions in the Bonasika Project Feasibility Study ("FS") and to produce industrial scale volumes of ceramic proppants in a full scale ceramic proppant production facility.

Bulk Test Pit Programme

Pit preparation, mining and ore beneficiation in the Bonasika 7 deposit commenced in October 2015 and was completed in March 2016. Final production volumes were consistent with the FS geological block model as follows:

Geological Block Model Reconciliation ('000mt)
Waste DFB RGB Total
Estimated Geological Block Model Volumes 69.4 17.7 12.0 99.1
Actual In Pit Progress Surveyed Volumes 59.8 17.2 14.1 91.1
Actual Recoverable Surveyed Volumes N/A 15.5 11.2 N/A

Notes:

  1. Direct Feed Bauxite (DFB).
  2. Regular Grade Bauxite (RGB).
  3. The difference between estimated and actual in pit progress surveyed waste volumes is a result of assumptions used in the bulk estimation of the overburden quantities. Accurate individual quantities of the overburden lithologies were unable to be ascertained from the drill hole logs and an average density of 1.8 mt/m3 was used to obtain estimated volumes. However, actual mining enabled the various waste lithologies and densities to be calculated with greater accuracy.
  4. The difference between estimated and actual in pit progress surveyed DFB volumes is a result of cautious selective mining to avoid contamination of the target DFB ore which resulted in the loss of DFB to the overlying and underlying RGB horizons.
  5. The difference between actual in-pit progress and recoverable surveyed DFB volumes is a result of DFB material lost to the stockpile base to avoid contamination.
  6. The difference between estimated and actual in pit progress surveyed RGB volumes is a result of cautious selective mining to avoid contamination of the target DFB ore which resulted in more ore reporting to the overlying and underlying RGB horizons.
  7. The difference between actual in-pit progress and recoverable surveyed RGB volumes is a result of RGB material used to repair haul roads and also lost to the stockpile base to avoid contamination.

3,000mt of DFB and 100mt of RGB was screened, crushed, dried and bagged for shipment to an offshore ceramic proppant production facility ("CP Facility"). Final production assay results were consistent with the FS geological block model as follows:

Geological Block Model Reconciliation DFB (%)
Al2O3 SiO2 TiO2 Fe2O3 LOI
Estimated Geological Block Model Assay Results 61.58 2.86 3.10 0.52 31.47
Actual 3,000mt Bagged Production Assay Results 62.60 2.13 2.78 0.48 32.01
Geological Block Model Reconciliation RGB (%)
Al2O3 SiO2 TiO2 Fe2O3 LOI
Estimated Geological Block Model Assay Results 58.04 6.68 2.70 0.49 28.04
Actual 100mt Bagged Production Assay Results N/A 6.87 2.72 0.49 N/A

Notes:

  1. The difference between estimated and actual SiO2 results for DFB is a result of not blending in the transition ore between the DFB/RGB (higher SiO2) assumed in the block modelling.
  2. Al2O3 and LOI results were not conducted on RGB as this product will not be used to produce ceramic proppants as part of the industrial scale proppant production trial. However, it will be used as sacrificial product at the commencement of the trial to clean out any contaminants in the CP Facility.
  3. The actual assay results for both DFB and RGB were also consistent with regular ROM in process assay results conducted during the bulk sample test pit programme.

Ceramic Proppant Production Trial

During April 2016, bagged DFB was transported from the Bonasika 7 deposit to the Georgetown port, loaded into containers and shipped to the CP Facility. A total of 2,400mt (2,300mt DFB/100mt RGB) was shipped with the production trial expected to be undertaken in July 2016. Ceramic proppant product is expected to be available for independent testing by recognised oil and gas industry laboratories in August 2016 and for market tests in select oil and gas wells in September 2016. Discussions are underway with oilfield service companies on potential field trials.

Ceramic Proppant Testwork

Following announcement of the FS results on June 18, 2015 and filing of the NI 43-101 Technical Report on August 4, 2015, further independent testwork has been conducted by recognised oil and gas industry proppant testing laboratories on upscale samples of First Bauxite's ceramic proppants. This includes upscale samples produced in the CP Facility. This testwork has confirmed the favourable results reported in the FS that, compared to the market leading high strength proppant (HSP) and ultra high strength proppant (UHSP) products, First Bauxite's products have:

  • superior strength
  • superior conductivity
  • comparable sphericity and roundness

Tenements and Permitting

In December 2015, the Government of Guyana ("GoG") granted the company a two year extension to the construction commencement date under the Bonasika Mining Licence ("BML") from January 31, 2016 to January 31, 2018. The Company has now commenced discussions with the GoG on the specific modifications that are required to the Mineral Agreement and BML to reflect the new FS scope. The Company has also submitted an application to renew its Environmental Permit expiring October 31, 2016. This reflects the new FS scope which has a much smaller footprint than the previous scope.

The Company has held the Tarakuli-Canje Permission for Geological and Geophysical Survey ("PGGS") since April 22, 2013. The PGGS expired on April 21, 2016 and the Company has applied to renew the PGGS for another three year period. This will allow the Company to undertake further exploration and evaluation of the PGGS with the aim of incorporating it within the new FS scope.

The Company will provide additional business updates as further progress is achieved on the various activities discussed above.
