Sampling of individual samples from previously released composite sample results return up to 3m @ 161 g/t gold
(inc. 1m @ 329 g/t gold from 101m in MR‐10/2015 ‐Dona Maria prospect)
The original 4m composite sample results from MR‐10/2015 returned 12m @ 35.13 g/t gold from 99m. Single metre samples from this composite were collected in the field, re‐submitted to the lab and returned;
8m @ 62.40 g/t gold from 101m including
3m @ 161 g/t gold from 101m and
2m @ 5.9 g/t gold from 107m
Individual samples are routinely done on composite samples with results >0.5g/t gold to more precisely define mineralised zones
New results from follow‐up drill core sampling from Dona Maria prospect, increases significant intercept in MD‐01/2015 from 3.4m @ 48 g/t gold (from 183.25m) to 8m @ 21.76 g/t gold from 179m
New results from follow‐up drill core sampling from Querosene prospect includes 1.03m @ 58.2 g/t gold from 88.46m in hole QD‐05/2015
Strong repeatability of composite versus individual samples across all of the prospects drilled in 204/15, is demonstrated and increases confidence in the drilling representivity
Global Resource Engineering commissioned to undertake preliminary economic assessment to assist with consideration of potential trial mining operation
Crusader has received encouraging results from a program of re‐sampling of composite samples that can better define mineralisation zones at the Juruena Gold Project. This sampling is implemented when the previously received composite drill sample results (see ASX announcements released on 18/12/2014, 17/03/2015, 08/05/2015 and 01/07/2015) return values over 0.5 g/t gold.
The Juruena Project (> 400km2 of contiguous tenements, 100% Crusader owned) is located in Central Brazil on the southern fringe of the Amazon basin. Situated on the western end of the prospective Juruena‐Alta Floresta gold belt (estimated to have produced ~7Moz Au), Juruena has been worked extensively by artisanal miners (garimpeiros) since the 1980s, producing an estimated 500koz of gold.
Crusader recently announced (ASX Announcement - 29 September 2015) a maiden resource for three prospects at Juruena, including the Dona Maria, Querosene and Crentes prospects. The maiden resource estimated a total of 1.3Mt @ 5.6g/t for 234koz Au.
Drill sample results -Composite comparison
A full table comparing the composite sample results (previously reported) and the newer individual metre results, as well as a graphical summary of the results, is presented below. The data shows that there is no significant bias between the composite sample results and the individual sample results (re‐composited for comparison).
Composite sampling (when several intervals of drilling are submitted as a single sample) is routinely implemented in RC drilling as a means to reduce assaying costs. The geologist on the drill rig, logs the hole and selects the most prospective sections‐ these are sampled on normal spacing‐ either 0.5m or 1m (depending on the prospect). Areas considered less prospective are composite sampled in order to ensure coverage of the entire hole. Once results are received, composite results above the nominal 0.5 g/t cutoff are re‐submitted in their original sample intervals, either 0.5m or 1m.
New diamond drill results -holes MD‐01/2015 and QD‐05/2015 (Dona Maria and Querosene prospects)
Crusader has received results from follow‐up sampling of diamond core which were recently cut, sampled and sent to the lab. The sections of core which were cut and sampled, were targeted after the initial samples results were received and interpreted, prompting follow‐up sampling in several holes. The full results are published in Table 2 below and illustrated in Figure 1. Highlights include;
MD‐01/2015 from 3.4m @ 48g/t gold (from 183.25m), has been extended to;
o 8m @ 21.76g/t gold from 179m‐ Dona Maria prospect
QD‐05/2015 1.03m @ 58.2 g/t gold from 88.46m - Querosene prospect
Significant intercepts are calculated based on a 1g/t lower cut‐off, no upper cut and up to 2m of consecutive internal dilution.
Preliminary Economic Assessment
Global Resource Engineering (GRE), a Denver based mining engineering firm specialising in providing geology and engineering services to developing and existing projects, has commenced work to assess the economics of a high‐grade trial mining operation at Juruena. This work will involve scoping level underground mine designs for Querosene and Dona Maria. GRE has substantial Brazilian experience and importantly completed work on similar projects also located in the Amazon regions of Brazil.

About Crusader
Crusader Resources Limited (ASX:CAS) is a minerals exploration and mining company listed on the Australian Securities Exchange. Its major focus is Brazil; a country Crusader believes is vastly underexplored and which offers high potential for the discovery of world class mineral deposits.
Crusader has three key assets:
Juruena Gold
The Juruena Gold Project is located in the highly prospective Juruena‐Alta Floresta Gold Belt, which stretches east‐west for >400km and has historically produced more than 7Moz of gold from 40 known gold deposits.
The Juruena Project has been worked extensively by artisanal miners (garimpeiros) since the 1980s, producing ~500koz in that time. Historically there is a database of more than 30,000 meters of drilling and extensive geological data.
Posse Iron Ore
The Posse Iron Ore Mine is located 30km from Belo Horizonte, a city acknowledged as the mining capital of Brazil and the capital of Minas Gerais state. The project had an indicated and inferred Mineral Resource estimate of 36Mt @ 43.5% Fe when mining began in March 2013. Posse is currently selling DSO into the domestic market. With an experienced mining workforce amongst a population of over 2.5 million people, the infrastructure and access to the domestic steel market around the Posse Project is excellent.
Borborema Gold
The Borborema Gold Project is in the Seridó area of the Borborema province in north‐eastern Brazil. It is 100% owned by Crusader and consists of three mining leases covering a total area of 29 km² including freehold title over the main prospect area.
The Borborema Gold Project benefits from a favourable taxation regime, existing on‐site facilities and excellent infrastructure such as buildings, grid power, water, sealed roads and is close to major cities and regional centres. The project's Ore Reserve includes 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 measured, indicated and inferred Mineral Resource Estimate of 2.43Moz @ 1.10g/t gold, remains open in all directions.

All drill‐hole data are recorded in Microsoft Excel spreadsheets and then stored in a digital database (Microsoft Access). Only Crusader's database administrator has the capacity to enter or change data. Standardised geological codes and checks have been employed to ensure standardised geological logging and required observations performed. The database is stored on a central server which is backed up weekly. Work procedures exist for all actions concerning data management. All historical (Lago) drill‐hole data were sourced from Lago data files; Crusader is in possession of the original electronic laboratory files. Original text files for assay, collar and survey were received for the Madison drilling. Original maps and reports and digital data were received from Lago Dourado. |
