Redcliffe Project
LOCATION: LEONORA, WESTERN AUSTRALIA
(PACRIM 100%)
The Project covers approximately 65 kilometres of strike length of the Mertondale Shear Zone along with parallel and associated structures. An estimated 400,000 ounces of gold has been produced from the Mertondale Shear Zone from historic mines and pits that operated in the 1980s and 1990s.
These include the shallow Nambi and Redcliffe pits that produced in excess of 90,000 ounces from within the Pacrim project area.
The Company’s Redcliffe Gold Project exploration led to the initial resource estimate of 151,000 ounces of gold, (consisting of an Indicated Resource of 385,000 tonnes @ 3.42g/t gold and an Inferred Resource of 1,678,000 tonnes @ 2.0g/t), with the Board confident of increasing the figure through further exploration.
Building on a very active exploration phase in 2008 Pacrim Energy Limited has recommenced field exploration since years-end.
Pacrim’s focus continues to seek further gold discoveries and to add to gold resources at the Redcliffe Gold Project. This will include the upgrading of the Golden Terrace South gold resource, further RC drilling, and advancement of planning for development of the most readily accessible and potentially economic gold mineralisation.
- Redcliffe Gold Project is the Company’s operational focus.
- Located near Leonora, 230km north of Kalgoorlie; the heart of Western Australia’s goldfields
- The region has numerous active mining operations with existing infrastructure
- Leonora district - prolific multi-million ounce gold deposits.
- Situated in an important regional structural setting; the Mertondale Shear Zone.
- Pacrim’s tenements include 65 to 70km strike length of the Mertondale Shear Zone and associated structures.
- Drilling at Nambi Pit shows strong continuity of gold lodes
- Redcliffe Pit / West Lode RC Drilling outlines further gold mineralisation
- The Company has discovered high grade gold at Golden Terrace South (GTS)
The recently identified 727 prospect is considered to have the capacity to add to the existing resource base with relatively shallow mineralisation.
During the March 2009 Quarter, an RC drilling programme at the 727 prospect was designed and carried out to follow up earlier RAB drilling intercept of 10 metres @ 4.92g/t gold. Composite samples from the drilling reported gave intercepts including 20 metres @ 3.08g/t gold.
Assaying of single metre splits has returned the best intercept of 10 metres 5.7g/t gold from only 2 metres deep. Individual metre assays within the intercept were up to 12.3g/t gold.
R drilling to date has indicated the presence of substantial intervals of gold mineralisation associated with gold n soil anomalism lying to the east of the main Mertondale Shear Zone. Additional drilling is required to thoroughly test the gold mineralisation to determine orientation, geometry and strike continuity. The occurrence of such shallow gold intercepts is regarded as extremely beneficial in seeking to delineate resources amenable to open pit exploration.

- Extensive infill required
The initial resource for Golden Terrace South calculated in mid 2008, was 16,000 tonnes @ 3.3g/t gold, for 44,000 ounces (Indicated and Inferred).This is based entirely on Pacrim drilling since discovery where no past mining has been carried out. Subsequent RC drilling has outlined a mineralised zone that continues at depth and to the south and remains open in those directions.
Pacrim Energy Ltd completed an RC programme in the March 2009 Quarter consisting of several holes aimed at testing the southern extension and a trial re-entry of an earlier RC hole where a previous contractor failed to attain the required depth. Drilling undertaken outlined further significant mineralisation including 7 metres @ 3.70g/t and 4 metres @ 3.58gt gold. Plus 10 gramme x metre intercepts shown emboldened on the following table.

The southern continuations of the gold mineralisation and deeper drilling have the potential to considerably expand upon the initial resource estimate.
RC drilling program
Subsequent to the data utilised for resource estimation, Pacrim Energy has completed additional RC drilling at the Golden Terrace South and Barry Prospects.
The drilling at Golden Terrace South was successful in extending the mineralised zone to the south to approximately 150 metres beyond the previously known mineralised zone (GTRC89-97). Results included 6 metres @ 3.15g/t, 7 metres @ 2.74g/t, 3 metres @ 4.60g/t, 3 metres @ 9.48g/t, and 4 metres @ 5.09g/t gold. Deeper drilling under the resource model also provided further encouragement with intercepts including 11 metres @ 3.13g/t and 10 metres @ 2.00g/t gold.
In addition to this work, further infill RC drilling has been carried out with better intercepts including 19 metres @ 5.57g/t, 8 metres @ 3.54g/t, 6 metres @ 4.57g/t and 3 metres @ 12.67g/t gold.
A re-interpretation of the initial resource estimate shell outlines has been in initiated and preliminary metallurgical test work has shown excellent characteristics with gold recoveries ranging from 90 to 100% from composite samples above the transition zone. Detailed geological mapping and extensions to the ground magnetic survey initiated early in 2008 were completed in December 2008.

NAMBI AREA PROSPECTS
The Nambi deposit is a robust silica/sulphide lode system that displays excellent continuity. The deposit is a series of north-south striking sub-vertical lodes that extend to a depth of 200 metres, open to the south and at depth. The estimate for the Nambi deposit reported 559,000 tonnes @ 2.9g/t gold, with 52,000 contained ounces (Indicated & Inferred).
Confirmation of the pit extents through further surveying may permit these resources to be increased in future estimates.
- Detailed mapping carried out over Nambi area
- 90,000 ounces produced from several open pits
- RC & diamond drilling of many targets carried out and to continue
Pacrim’s previous RC drilling confirmed the existence of substantial gold mineralisation at the Redcliffe Pit prospect with the better intercepts being 8m @ 4.09g/t, 6m @ 4.46g/t, and 4m @ 3.65g/t gold from above the base of oxidation. Intercepts of 4m @ 3.10g/t and 5m @ 2.05g/t gold were returned from fresh rock with associated traces of fresh sulphides. The mineralisation lies beneath, and along strike from the former shallow open pit and occurs in both mafic and felsic lithologies with silica/sericite/biotite alteration over a strike length in excess of 300 metres.
Results from further RC drilling at West Lode and Redcliffe Pit were compiled during the March 2008 quarter. The best result from the drilling at West Lode was 17m @ 2.84g/t gold. A gold bearing quartz zone south of the Redcliffe Pit returned results of 3m @ 10.44g/t and 2m @ 9.07g/t. This new zone is open in all directions.
- Previous open pit in oxide zone
- Multiple gold lodes
- PRE RC intercepts: 8m @ 4.09g/t, 6m @ 4.46g/t, 4m @ 5.16g/t gold
- Initial PRE resource 31,000oz
WEST LODE
- Previous shallow pits – average grade of 3.2g/t gold
- Multiple gold lodes
- PRE RC intercepts: 17m @ 2.84g/t, 3m @ 13.57g/t gold
- Initial PRE resource 15,000oz
RC drilling is planned at the Nambi South Pit, approximately 400 metres along strike from the main Nambi Pit.
A detailed programme of rock chip channel sampling has revealed numerous highly mineralised gold zones assaying up to 34.2 g/t gold.
The Nambi South Pit was excavated as a test pit during the time of operation of the main Nambi Pit. The target zone was only partially delineated by drilling and included an intercept of 30m @ 4.88g/t gold. Work carried out by Pacrim has demonstrated that a substantial portion of the mineralised zone remains in situ.
Twenty two samples taken from the walls of the bottom of the pit averaged 5.03 g/t gold. These included weighted averages of 7m @ 8.64g/t, 8m @ 3.61g/t, 5.5m @ 8.54g/t, 7.3m @ 5.00 g/t gold.
- Previous RC drilling 30m @ 5g/t
- Pacrim channel sampling confirms in-situ mineralisation: 8.7m @ 4.52g/t, 7.6m @ 4.17g/t and 6.0m @ 5.90g/t
- Cross structure controlled shoot
- Further drilling planned
- Expect extensive down plunge continuity
The mineralised zone exposed in the Nambi Pit is sub-vertical and consists of a silica/pyrite/pyrrhotite/biotite lode with variable, amphibole, chlorite & sericite.
Pacrim’s first round of RC drilling in mid 2007 tested a 370 metre strike length below the pit floor to a depth of around 110 metres where results included, 10m @ 8.45g/t, 6m @ 6.66g/t, 5m @ 8.02g/t gold.
A second round of drilling, consisting of 9 deeper RC holes demonstrated continuation of the gold mineralised silica/sulphide lode to approximately 160 metres vertical depth (~100 metres below the pit floor).
A south plunging shoot of higher grade mineralisation is interpreted and has returned better intercepts of 7m @ 6.12g/t, 5m @ 5.63g/t, and 4m @ 4.11g/t gold.
Two additional mineralised zones have been discovered toward the northern end of the pit. The zones, referred to as E1 and E2, lie to the east of the main lode and have enhanced the gold potential of the Nambi Pit environs and they indicate the likely presence of further high grade shoots.
The second round of RC drilling intersected the E1 & E2 zones at shallow depths in several holes with results including 2m @ 12.70g/t, 3m @ 4.90g/t, and 2m @ 7.92g/t gold.
A third round of drilling is to test the zone at greater depth and to provide diamond core for preliminary metallurgical test work including rock density measurements.
- 32,500oz historically mined
- Strong silica sulphide lode
- Best intercept 10m @ 8.45g/t gold
- Continuous down to 200m. Still open
- 400m strike length
- Initial PRE resource 52,000oz (559,000t, @ 2.9g/t gold)
Two diamond drill holes were designed to test the main zone at a greater depth and to provide diamond core for preliminary metallurgical test work. Two diamond tails were drilled for 331.4 metres carrying on from 100 metre deep RC pre-collars. Holes have been geologically logged, and density work has been completed. Both the main lode and the E1 lode were intercepted in the holes, indicating the ore body continues at depth to vertical depth of 200 metres.

Pacrim’s exploration has identified a possible 20 kilometre strike length of an ultramafic rock sequence prospective for nickel. The zone lies within the Redcliffe Project tenements, to the east of, and approximately paralleling, the Mertondale Shear Zone. Announced in the December 2008 quarterly activity report, Pacrim’s initial RC drilling in late 2008 returned an impressive intercept of 98 metres @ 0.40%Ni, including 7 metres @ 1.05% nickel.
The RC drilling has confirmed the existence of a substantial zone of nickel mineralisation with a true width of approximately 75 metres delineated by concentrations of nickel in excess of 1000ppm. Within this zone, two higher grade zones of 2500ppm nickel occur.

Petrological work on drill chips was carried out to assist in geological interpretation of the nickel mineralisation. The work has confirmed the presence of sulphide mineralisation including chalcopyrite and nickel-cobalt sulphides (millerite).
Field investigations in the March Quarter have included reconnaissance mapping, collection of further samples for geochemical analysis and selected petrography to build detailed geological knowledge of the considerable strike length. Targets generated from this work will be prioritised and future proposed exploration programmes will be designed to include extensive geophysical surveying to seek disseminated and massive sulphide deposits.
IN ADDITION TO THE ADVANCED PROSPECTS WITH DEMONSTRATED RESOURCE POTENTIAL, THERE ARE NUMEROUS ATTRACTIVE EXPLORATION TARGETS WITHIN THE REDCLIFFE GOLD PROJECT.
- Targets for further drilling as defined by previous drill hole chemistry
- Much of the drilling was shallow, in depletion zone
- Any gold anomalism is important and worthy of follow up
- Surface depletion and extensive cover ensures subtle gold anomalism is important in target definition
- Many targets to be tested
- Interpretation shows Mertondale Shear Zone
- Importance of cross structures evident (M3/4 & M5)
- Further targets from geophysics combined with soil geochemistry and drill hole gold geochemistry
BARRY & KELLY
RC drilling at the Barry Prospect followed up historic anomalous drill intercepts of 4 metres @ 3.47g/t, 2 metres @ 1.49g/t and 6 metres @ 3.03g/t gold. Anomalous gold intercepts were returned from two interpreted sub-vertical parallel zones of mineralisation, striking north-south over 160 metres.
One of the zones is proximal to a graphitic shale unit, with the best intercept of 3 metres @ 3.90g/t gold. The geology of the Barry Prospect is similar to Pacrim’s Golden Terrace North and Golden Terrace South prospects and clearly warrants the drilling of further holes.

- Extensive gold anomalism outlined by previous drilling
- Similar in character to GTS
- Many targets show potential for additional resource definition
THE HUB
The Hub prospect consists of projected continuations of the Mertondale Shear Zone extending between the Nambi and Golden Terrace prospect groups within Pacrim’s tenements. Recent interpretation of magnetic data by Pacrim suggests favourable structural settings exist, with several disruptive cross-cutting features. RAB drilling has intersected projected trends of the same suite of lithologies that are host to gold mineralisation elsewhere along the Mertondale Shear Zone. Several plus 1g/t intercepts have been returned from drilling and require additional RAB drilling to expand the target gold definition.
