Goldcliff Acquires Large Platinum-Gold Land Position

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 17, 2008) - George W. Sanders, President of Goldcliff Resource Corporation (TSX VENTURE:GCN), is pleased to report that Company has acquired a large platinum-gold land position in the Princeton mining region in south-central British Columbia. The Tulameen claims are 100%-owned by the Company and consist of one contiguous block that totals 45,245 hectares (111,755 acres). Located in the historical Princeton mining region, the Goldcliff claim area is situated between the Tulameen platinum district and the Copper Mountain district. The Tulameen platinum district was an important historic producer of placer platinum (20,000 ounces) and the Copper Mountain district was a significant producer of copper and gold (168 million tonnes).

The Goldcliff claims cover several of the historic placer producing platinum-gold creeks, copper-gold showings and outcrops of intrusive and country rocks that are favourable for mineral deposits in the Princeton mining region. The Tulameen platinum district, which contains several lode platinum occurrences (Minfile), has a reported historic placer platinum production of 20,000 ounces platinum. The potential economic platinum values associated with the lode occurrences range from 2.5 to 16.0 grams platinum per tonne. The Copper Mountain district has a historic production of 168 million tonnes of ore with an average grade of 0.46% copper and 0.14 grams per tonne gold.

The modern data base has enhanced the exploration potential of Goldcliff's claims in the Princeton mining region with respect to platinum, gold and copper. Readily accessed by road, the Goldcliff claims are ideally positioned for exploration in the Princeton mining region.

Tulameen Platinum District

From 1889 to 1936, the Tulameen platinum district was recognized as the most important producer of placer platinum and gold in North America. Several of the creeks in the Princeton mining region had 20,000 ounces of reported platinum production. The Goldcliff claims cover the majority of the creeks that produced placer platinum and gold.

Referred to as the Tulameen Complex, the lode platinum occurrences in the Tulameen platinum district are associated with ultramafic-mafic intrusive rocks. The Tulameen Complex contains several lode platinum occurrences that have platinum values ranging from 2.5 to 16.0 grams platinum per tonne. The placer platinum deposits in the creeks are the result of the de-gradation and erosion of the lode platinum occurrences in the Tulameen Complex.

Tulameen Claims Regional Geology

The Tulameen claims cover an area of 45,000 hectares of geology that is favourable for the exploration of platinum, palladium, gold and copper deposits. The claims have extensive overburden. The Tulameen platinum district is located to the northwest and the Copper Mountain copper-gold porphyry-deposits are located to the southeast of the claim block. In the Tulameen platinum district, the Tulameen Complex containing the lode platinum occurrences is partially exposed. There are similar Tulameen Complex rocks that occur on Goldcliff's claims.

The Tulameen Complex of ultramafic-mafic intrusive rocks is classified as an Uralian-Alaskan-type complex. The Uralian-Alaskan complexes are a major contributor of platinum group metals (PGM) in the world (Google).

In the Tulameen district, the platinum metal is a mineral alloy that was identified in 1974 as tulameenite (BC Geology). Tulameenite occurs in other Uralian-Alaskan complexes in the world that are associated with platinum production. Tulameenite is a ferronickelplatinum alloy with a mineralogical composition of Pt-Fe-Cu-(Ni).

World Platinum Producers

Globally, the Uralian-Alaskan complexes are a significant source of platinum group metals (PGM). In Alaska, the Goodnews Bay Complex had 647,500 ounces of platinum recovered from its placers. The Salt Chuck lode mine produced 661,771 ounces of platinum and palladium as a by-product of copper ore from the Salt Chuck Complex.

In Russia, the Ural region is a significant placer and lode producer of PGM from a Uralian-Alaskan complex. The placer deposits were discovered in the Ural Mountains in 1823 and have been producing PGM continuously up to the present. The historic PGM production from placer and lode deposits is not well documented but is considered significant. In the late 1980s, lode deposits reached peak platinum production of around 4.0 million ounces of palladium and 1.0 million ounces of platinum. In 2005, the lode deposits reported production of 751,000 ounces of platinum and 3,133 million ounces of palladium in the Ural region (Google).

The other important producers of PGM in the world are in South Africa (Bushveld Complex) and in the USA (Stillwater Complex). The South Africa grades of PGM metal are typically between 3 and 6 grams per tonne. The USA grades of PGM metal are typically between 10 and 20 grams per tonne (Google).

In the Princeton mining region, the Tulameen placer-platinum deposits have produced a reported 20,000 ounces of platinum. The lode platinum occurrences in the Tulameen platinum district range in values from 2.5 to 16.0 grams platinum per tonne.


The Goldcliff claims are located in the Princeton mining region which has favourable geology for multiple mineral deposits discoveries of platinum, gold and copper.

The Goldcliff claims in the Princeton mining region are 100%-owned and are readily accessed by road.

The Tulameen Project claim acquisition is consistent with Goldcliff's management policy to acquire high quality exploration projects.
