The 100% owned Borborema Gold Project is located in the Seridó area of the Borborema province in north eastern Brazil. The project consists of three mining leases covering a total area of 29 km² plus freehold title to the property over the main prospect area. The Borborema Gold Project is enhanced by good on-site facilities and excellent infrastructure, such as buildings, grid power, water, sealed roads and close proximity to major cities.
Maiden Ore Reserve and Total Mineral Resource
The project’s Maiden Ore Reserve was announced in November 2012.
87% of Measured and Indicated Resources from the July 2012 JORC Resource estimate were converted into Proven and Probable Ore Reserves of 1.61Moz of mineable gold from 42.4Mt @ 1.18g/t (0.4 & 0.5g/t cut-offs for oxide & fresh). The Mineral Resource remains open in all directions.
The Ore Reserve is based upon the Mineral Resource estimate for Borborema released in July 2012.
Borborema’s estimated Proven and Probable Ore Reserves will form an integral part of the Bankable Feasibility Study (BFS) due for completion in the first quarter of 2013. The BFS will detail costs and benefits of a 4Mtpa gold mine with projected average production of 150,000 oz pa (years 2-10).
A positive Pre-Feasibility Study was completed in September 2011. It examined a smaller 3Mtpa operation, producing an average of 130,000 oz pa. The BFS was launched as a result of the PFS confirming a robustly economic project.

As part of the ongoing BFS, Crusader has conducted preliminary pit optimisations, using the July 2012 Mineral Resource estimate. The 43Mt @ 1.2 g/t Au for 1.66 Moz Au are contained within an economic pit-shell, constrained using parameters detailed in Table 3 below.
Crusader is considering 3 pit shells in terms of scheduling with the starter pit shell estimated as having a three year life, strip ratio of 3.0 and a grade of 1.30g/t.
Two other pit shells have been selected as guides for progressive pits. The results for all 3 pit-shells, including the contained tonnages and grades are presented below;
The pit shell detailed in Table 2 returned the highest average discounted cash flow for the project with a projected life of 10.5 years at a throughput rate of 4 Mtpa. The summary results are presented below;
The pit optimisations of the Borborema Gold Project were completed by consultants working on the BFS. The optimisations were completed on the July 2012 block model containing all Mineral Resources categories using Whittle software. The main optimisation inputs are below, as provided by Crusader and the study team and are preliminary parameters only.
An additional >4,500km2 of tenements within the Seridó belt, which hosts Borborema, have been acquired by the company and regional exploration is underway.
