Chalice Gold: Regional Exploration Program Ramps Up at Zara

Further Encouraging Results From Zara North; New Soil Anomaly Identified at Fah Prospect


- Further results from Zara North confirm strong stream sediment anomalism over 10km strike length

- Follow-up and infill sampling over this target well advanced with new areas of artisanal workings identified

- Soil sampling at Fah prospect defines extensive gold anomaly

- Large heliborne magnetic and radiometric survey underway

PERTH, WESTERN AUSTRALIA--(Marketwire - Dec. 20, 2010) - Chalice Gold Mines Limited (TSX:CXN)(ASX:CHN) today announced it is ramping up regional exploration at its Zara Gold Project in Eritrea, East Africa, with a focus on identifying new prospects to increase resources in the vicinity of its flagship Koka Gold Deposit, which hosts an indicated Mineral Resource of 840,000oz at a grade of 5.3g/t gold.

Follow-up geochemical sampling and geological mapping on the Zara North licence continues to confirm previously reported gold anomalism (see announcement to the ASX dated 22 July, 2010). Identifying the source of this anomalism will be a focus for intensive exploration over the coming months but work currently underway has identified several zones of previously unknown artisanal workings within the source area for the anomalies.

In addition, results from a soil sampling program at the Fah prospect, located 5 kilometres southeast of Koka, have revealed extensive high order gold anomalism.

Further, in order to better assess the exploration potential of the broader Zara licences, which encompass 615 sq km, a large heliborne magnetic and radiometric survey has commenced over the Zara licences with the objective of identifying alteration zones typically associated with Koka-style gold systems.

The Company is steadily increasing its exploration capability through the addition of resources and personnel and plans to use helicopter support to expand and accelerate these programs.

1. Koka North Stream Sediment Geochemistry

As reported the ASX on 22 July 2010, results from a reconnaissance Bulk Leach Extractable Gold (BLEG) drainage sampling program completed over the Zara North and Zara South Prospecting Licenses outlined an extensive zone of gold anomalism in the western half of the Zara North tenement.

Follow-up infill sampling using conventional stream sediment sampling has confirmed that this gold anomalism extends over a strike length of ~10 km (see Figure 1) with values of up to 876ppb gold recorded. Field checking has revealed artisanal workings in several of the anomalous drainages, often associated with a semi-continuous high-strain zone with intense carbonate-sericite alteration and quartz veining over a 30-50m wide zone that extends the length of the anomalous zone (see Figure 2). Such shearing and alteration is often related to gold systems such as Koka. Reconnaissance rock chip sampling along this zone has returned assays of up to 11 g/t gold in a grab sample.

Chalice has recently commenced a program of detailed geological mapping and soil sampling to identify both the source and extent of the anomalism in the Zara North tenements. This program will be a major focus over the coming months and the Company has assigned additional technical staff to expedite its progress.

2. Aeromagnetic and Radiometric Survey

An extensive airborne magnetic and radiometric survey covering the Zara North, South and Central properties has commenced and is progressing well.

This 12,750 line kilometre survey will help define the regional geological structure, alteration patterns and granitoid suites/phases that may be associated with gold (and possibly other) mineralisation.

3. Fah Soil Sampling

Results from a recent geochemical survey over the Fah prospect, located 5km southeast of Koka (see Figure 1), have been received. They reveal a robust gold-in-soil anomaly extending over a strike length exceeding 1 kilometre and exceeding 100ppb gold (see Figure 3). It encompasses the main historical artisanal workings at Fah and overlies an intensely altered and finely quartz stockworked microgranite suggestive of a strong mineralising system. Two scout holes drilled beneath the main artisanal workings intersected disseminated sulphides associated with multiple narrow quartz stringers as well as several larger metre-scale quartz-sulphide veins. Assays from these holes are currently pending.

About the Zara Gold Project

The Zara Project comprises four Exploration Licenses and two Prospecting Licenses (currently being converted to exploration licences) covering an area of 615km2 situated in northern Eritrea, approximately 160km northwest of Asmara city. Chalice currently holds a 100% interest in the project subject to the Eritrean Government's right to acquire a further 30% interest, at fair value, in any mining project in addition to a 10% carried interest.

The Zara Project encompasses a portion of the Arabian-Nubian Shield, which straddles the Red Sea. This area is highly prospective for gold and offers similar potential to some of the better-known parts of West Africa, such as Ghana and Burkina Faso, but is still very much in its infancy in terms of exploration. Mines and projects within the Arabian Nubian Shield include Sukari gold mine and the Bisha gold-copper-zinc VMS mine currently under construction. Most of Chalice's 615 square kilometre tenement package at Zara remains virtually untouched by modern exploration.

The Koka Gold Deposit, within the Zara Project, contains a Probable Mineral Reserve of 4.6 million tonnes grading 5.1 grams of gold per tonne and containing 760,000 oz of gold. This is contained within an Indicated Mineral Resource of 5.0 million tonnes grading 5.3 grams of gold per tonne containing 840,000 oz of gold.

As Chalice announced to the Australian Securities Exchange ("ASX") on 13 July 2010, key parameters of the project obtained from a Feasibility Study for the Koka Gold Deposit prepared by Lycopodium Minerals Limited and completed in July 2010 are as follows:

  • Average life-of-mine total cash operating costs* of US$338 per oz of gold;
  • After-tax net present value at a 5% discount rate of US$196 million, life-of-mine earnings before income taxes, depreciation and amortisation* of US$589 million and an after-tax internal rate of return of 35% at a gold price of US$1,200/oz;
  • Average annual gold production of approximately 104,000oz per year with gold production totalling 731,000oz;
  • Forecast mine life of seven years at a mill throughput of 600,000 tonnes per annum, rising to 700,000 tonnes per annum from year 5;
  • Estimated start-up capital cost of US$122 million.

Sampling Procedures and Quality Assurance

Soil samples are collected from sites located using GPS. Soil material is collected from a depth of 5-20cm with a plastic trowel and sieved to 180µm mesh using stainless steel sieves. Approximately 120 grams of material is placed into two small Kraft paper sample bags, sealed and tagged with a unique number, with both bags being numbered identically. One of these samples is sent to NATA-accredited Intertek-Genalysis Laboratories in Perth Western Australia for assay whilst the other sample is retained as a duplicate in the Chalice Eritrea sample storage.

Samples are analysed for multi-element suites using ICP-OES after aqua regia digest on a 25g sub-sample and vacuum filtering prior to voluming to preclude errors resulting from insoluble residues. Au is analysed as an additional element utilizing Graphite Furnace AAS. Chalice Gold Mines inserts field blanks, field duplicates, repeats and certified reference materials (CRMs) into its sample sequences sent to the routine and umpire laboratories to control the accuracy and reliability of the analytical results.

Blank samples are introduced at the rate of 1 per 20 to 25 routine samples to test contamination during sample preparation. Certified reference materials (CRMs) are submitted with all sample batches at the rate of 1 per 20-25 routine samples. The CRM's inserted have values ranging from very low to high grade.5% of the returned coarse reject samples are routinely submitted to an umpire laboratory (Ultra-trace Laboratories, Perth, Western Australia) to test the analytical precision of the principal laboratory. Standard samples are included at a rate of 1 per 20 routine samples and there is at least one standard per submission. The Company monitors the QA/QC information to ensure there are no systematic biases or overall analytical quality issues.

Rock-chip samples are collected and assayed in essentially the same manner except that the sieving step is omitted and 1-2 kg of sample is collected and bagged in a heavy-duty plastic bag before dispatch to Intertek-Genalysis Laboratories.
