Continental Minerals Corporation and Great China Mining Inc.: Drilling Continues to Expand Xietongmen Deposit

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 30, 2006) - Continental Minerals Corporation (TSX VENTURE:KMK)(OTCBB:KMKCF) and Great China Mining Inc. (OTCBB:GCHA) announce the results from twenty-eight (28) additional core holes drilled in 2006 at the Xietongmen copper-gold deposit, located 240 kilometres west of Lhasa in Tibet, People's Republic of China.

Drilling in 2005 outlined a significant porphyry copper-gold deposit, with excellent potential for expansion. The objectives of the comprehensive 2006 program are to fully assess the resource potential of the project and initiate programs for a feasibility study and environmental and social impact assessments. The studies are targeted for completion in 2007.

Eight rigs are currently active at site in the planned 22,000-metre program, testing the extensions of the Xietongmen deposit. Long intervals with excellent grades of copper and gold continue to be intersected. The current drilling is testing all sides of the deposit, defining the eastern and southern limits as well as stepping out further to the north and to the west.

In the east, drill hole 6087, section 3249200N, intersected 180.5 metres grading 0.85% copper equivalent (CuEQ), including a higher-grade section of 92 metres averaging 1.09% CuEQ. In the same area on section 3249100N, holes 6094 and 6098 intersected wide intervals of excellent grade. Hole 6094 intersected 165 metres averaging 0.98% CuEQ, including two high-grade 30 metre sections of greater than 1.40% CuEQ. This section has extended the deposit a further 100 metres to the east.

In the south, significant intersections were made along a fence of four holes on section 3248800N, extending the deposit a further 100 metres south. Holes 6100, 6103, 6106, and 6110 intersected high grade copper mineralization over 300 metres along the section. The best intersections were in hole 6100 with an interval of 64 metres averaging 0.93% CuEQ and 100 metres to the west, hole 6110 intersected 51.9 metres averaging 0.92% CuEQ.

In the north, hole 6096 on section 3249350N has extended the deposit for another 50 metres to the north, where the deposit remains open. Hole 6096 intersected an interval of 160.3 metres averaging 0.62% CuEQ.

In the west, holes 6084, 6093, 6095, 6097, 6101 and 6102, all intersected mineralization and extended the deposit to the west by 150 metres with the best intersection in hole 6093 with an interval of 130.8 metres averaging 0.77% CuEQ.

A Table of Assay Results is attached. A Property Location Map, a Drill Hole Plan and Cross Sections are posted on the websites: www.continentalminerals.com & www.greatchinamining.com.

In conjunction with the targeted technical programs, an expanded community engagement program is underway. A community relations manager and staff from Tibet have been hired to advance this important work. The objectives are to describe and discuss the project, to get input on it, and to explore opportunities for direct, tangible benefits for local residents and communities. Hence, active dialogue with the local residents in the Tibetan villages and the various authorities in the region will be ongoing in order that the project proceeds in a manner that respects local socio-economic priorities and incorporates a high standard of environmental management.

Continental and Great China Mining recently announced preliminary agreements between Continental and certain principal Great China Mining shareholders, whereby the companies will be merged to unify 100% ownership in the Xietongmen property in Continental (see joint news release April 13, 2006). Completion of the merger is subject to a number of conditions including the execution of definitive merger documentation, and shareholders and regulatory approvals, and is likely to complete in the third quarter of 2006.

Mark Rebagliati, P.Eng., a Qualified Person as defined under National Instrument 43-101, is supervising the drilling program and quality assurance and quality control ("QAQC") programs on behalf of Continental Minerals Corporation. The program includes rigorous QAQC procedures. Acme Analytical Laboratories of Vancouver, BC, an ISO 9001:2000 accredited laboratory, performs the sample preparation and assaying for the project. Gold analysis is by 30 g Fire Assay fusion with an Inductively Coupled Plasma-Emission Spectroscopy (ICP-ES) finish. Copper assays are done by four acid digestion with an ICP-ES/ICP-Mass Spectroscopy finish. Continental includes standards, blanks and duplicates in addition to the laboratory's internal quality control work.

(1) Copper and gold equivalent calculations use metal prices of
US$1.25/lb for copper and US$450/oz for gold.
Adjustment factors to account for differences in relative
metallurgical recoveries for gold and copper will depend upon
the completion of definitive metallurgical testing.
CuEQ equals Cu % + (Au g/t x 14.47/27.56)
AuEQ equals (Cu % x 27.56/14.47) + Au g/t
