The drilling program at Red October is aimed at:
-
providing grade control near the current production area; and
-
infill of existing resources to define and de-risk potential future mining areas.
Results received to date are encouraging for the Lionfish Phase 1 program and Marlin 410 program (refer to Figure 3 below). Both the Lionfish lodes and Marlin 410 lode are close to existing workings, and offer the potential for adding ounces into the mine plan relatively quickly.

Lionfish Phase 1
The Lionfish Phase 1 program aims to test the continuity of lodes and high-grade shoots below the previously mined N-1255 level, with a view to completing the infill and defining mineable ounces.
High grades evident within the main Lionfish lodes (HW 357 and HW 356) and a subsidiary structure (Splay 555) down-plunge of the N-1255 level have been tested with four drillholes (ROGC747 to ROGC750 inclusive). A possible grade shoot north of the existing N-1255 level workings was also tested with one drillhole (ROGC751).

Marlin 410
The Marlin 410 program aims to infill two potential mining levels below the previously mined S-842 level. This area presents a compelling mining opportunity and is easily accessible by continuing the South Decline downwards, with all mining infrastructure in place. Ten drillholes have been completed for this purpose, with 9 drillholes still pending assays.

Red October Mine Geology Background
The Red October deposit is hosted within a lithology package that dips steeply to the northwest that is interpreted to be the northern limb of a district scale NE-trending antiform. The deposit is centred on a shale unit that separates a footwall of tholeiitic pillowed basalts and a hanging wall succession of talc-carbonate to serpentinised ultramafic and high-Mg basalt with sparse interflow sediments. Near the top of the ultramafic-high Mg basalt sequence are thinly bedded iron-rich chert sedimentary units with variable sulphide content.
The ore system throughout Red October gold mine is structurally-hosted, with mineralised moderatesteeply dipping structures present in three main orientations (in RO Local grid); north striking, northeast striking, north-west striking.
Mineralisation occurs as shear-hosted lodes or shear vein/breccia style lodes, with both styles quite visible in contrast to the host rock. Mineralisation is associated with moderate-strong wall-rock hydrothermal alteration assemblages and sulphides, with biotite, muscovite, sericite, quartzcarbonate-calcite and pyrite commonly observed. Rheology contrasts, structural junctions and dilational zones have provided fluid pathways and opportunities for deposition of gold-bearing sulphides and coarse gold.
Further updates will be provided as more information comes to hand as the drilling program continues and assay results are returned.

| accuracy and precision. Sample preparation checks for fineness are carried out to ensure a grind size of 85o/o passing 75 microns. The laboratory performs a number of internal processes including standards, blanks, repeats and checks. Industry best practice is assumed for previous holders. HistoricQAQC data is stored in the database but not reviewed. |
|
| Verification of sampling and assaying • The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• Significant intercepts are verified by the Geology Manager and corporate personnel. • No specific twinned holes have been drilled at Red October but underground diamond drilling has confirmed the width and grade of previous exploration drilling. • Primary data is collated in a set of excel templates. This data is forwarded to the Database Administrator for entry into a secure SQL database with inbuilt validation functions. Chips from RC drill holes are stored in chip trays for future reference. Remaining half core is stored in core trays and archived on site. Hard copies of face mapping, backs mapping and sampling records are kept on site. Digital scans are also kept on the corporate server. Data from previous owners was taken from a database compilation and was validated as much as practicable before entry into the Matsa database. • No adjustments have been made to assay data. First gold assay has been utilised by Saracen for resource estimation. Re-assays carried out due to failed QAQC will replace original results, though both are stored in the database. |
| Location of data points • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. |
• All drill hole collars are picked up by certified surveyors using a Leica Theodolite with an expected accuracy of +/~2mm. A DHS DeviGyro OX Kit was used for rig setups in addition to surveyed collar positions. Underground faces are located using a Leica Disto with an accuracy of+/-1mm from a known survey point. Surveys are carried out downhole during diamond drilling using a DHS DeviGyro OX Kit. Previous holders' survey accuracy and quality is generally unknown. • Saracen’s surface exploration campaigns involved RC holes being gyroscopically downhole surveyed by ABIMS where possible once drilling was completed. • A local grid system (Red October) is used. It is rotated 44.19 degrees east of MGA_GDA94.The two-point conversion to MGA_GDA94 zone 51 is: ROEast RONorth RL MGAEast MGANorth RL Point 1 5890.71 10826.86 0 444223.25 6767834.66 0 Point2 3969.83 9946.71 0 442233.31 6768542.17 0 Historic data is converted to Red October local grid on export from the database • DGPS survey has been used to establish topographic surface |

| magnetic anomaly on Lake Carey between the islands considered analogous to Sunrise Dam | |||
| in 1993. Aircore and RC drilling was carried out to define what would become the Red October | |||
| pit. Sons of Gwalia entered into a joint venture with Mount Burgess, carrying out RC and | |||

| dominated by ultramafic flows interbedded with high-Mg basalts. Prehnite- pumpellyite facies | |||
| are evident within both the tholeiitic basalts and komatiite flows. Sulphide mineralisation is | |||
| hypothesised to have been caused from interaction with an auriferous quartz vein, which has | |||
| caused the intense pyrite-defined ductile textures of the shale in the upper levels. The fluid is | |||
| believed to have been sourced from the intruding granitoid to the (grid) south of the deposit. | |||
