               Zheng Guang to Produce High Grade Zinc Concentrate

Leyshon Resources Limited ("Leyshon") (ASX & AIM: LRL) is pleased to announce
that it expects to produce a high grade zinc concentrate as well as gold and
silver at its Zheng Guang project in Heilongjiang, northeast China.

This comes a fortnight after Leyshon announced a significantly increased and
upgraded resource estimate at Zheng Guang.

Independent metallurgical consultancy Metallurg of Australia has reported on a
testwork programme undertaken by AMMTEC (Australian Metallurgical & Mineral
Testing Consultants) of Western Australia.

The report concludes that the treatment of the Zheng Guang ore can produce gold
and silver metal through a conventional carbon in leach circuit and a high grade
zinc concentrate through the addition of a flotation circuit.

Gold and silver recoveries in the carbon in leach circuit are expected to be 89%
and 74% respectively and 84% and 74% in the flotation circuit. Zinc recovery of
over 90% is expected producing a saleable concentrate assaying over 45% Zinc.

Managing Director Paul Atherley said today "We are delighted with these testwork
results and the rapid development of a process route which will significantly
increase project revenues through the sale of a high grade zinc concentrate."

The proposed process route designs are based on a 1.5 million tonne per annum
plant which will treat the near surface oxide and transition ores through a
conventional carbon in leach circuit producing around 75,000 ounces of gold and
210,000 ounces of silver per annum.

The proposed flotation circuit will be added to treat the zinc-rich deeper
sulphide ores. The circuit will comprise whole of ore flotation to produce a
combined metal concentrate which will be reground and then leached to produce
around 100,000 ounces of gold and 220,000 ounces of silver metal and then
refloated to produce 17,000 tonnes of zinc concentrate containing 7,000 tonnes
of zinc.

Work has commenced on the optimization of these process routes focusing on the
improvement of gold and silver recoveries and optimising grind size and reagent
consumption and the application of flotation to very low zinc grade ores. The
results of this work together with mine design and the overall project economics
will be reported in due course.

Leyshon's strategy is to rapidly bring Zheng Guang into production and to
increase the joint venture's exploration licence holdings over an area it
believes to be host to a large mesothermal and epithermal gold system which has
yielded considerable alluvial and surface gold, but as yet has been unexplored
by modern exploration methods.

Background Information

Leyshon

Leyshon is rapidly advancing the Zheng Guang gold zinc project to production
status and is aiming to jointly develop it as the first ever Sino Foreign owned
mine in the mineral rich province of Heilongjiang.

In March 2007 independent resource consultancy Hellman and Schofield Pty Ltd of
Australia made a recoverable resource estimate of 1.21 million ounces of gold,
3.72 million ounces of silver and 94,000 tonnes of zinc.

Leyshon's partner, the Qiqiha'er Brigade of the Heilongjiang Bureau of Geology
and Mineral Resources, one of the largest organizations of its kind in China, is
providing a range of services to the joint venture from its complement of 4,000
technical staff, drill rigs, laboratory and other technical facilities. This
valuable support is enabling the project to rapidly move ahead on an extremely
cost effective basis.

Leyshon has completed its expenditure requirements to earn its 70% interest and
has recently entered into a 20 year agreement with Qiqiha'er Brigade for the
financing, development and mining of the project.

Leyshon has its main operating office in Beijing and is one of the very few
foreign mining companies with its Chairman, Managing Director and Chief
Operating Officer all based in China.

AMMTEC

AMMTEC, Australian Metallurgical & Mineral Testing Consultants based in Western
Australia is one of the world's largest metallurgical and mineral testing
consultancies with a clientele that includes some of the world's major mining
groups.
