TVN Corporation (ASX: TVN) has been granted a trading halt by the ASX pending an announcement 'relating to material results of the company's current drilling program and associated assay results', with the shares placed in pre-open.
Investor interest in the stock was sparked earlier in the month, and for good reason, with the intersection of a 137 metre thick coal system in a down hole at the Nuurst project in central Mongolia.
The result - a 74% share spike on the day.
What helped boost investor interest is the exploration target at Nuurst of 50 to 100 million tonnes assumed a coal thickness of just eight metres.
Nuurst is statically located six kilometres from existing rail infrastructure, providing low cost access to the key coal export markets of China, South Korea and Japan.
What is so fascinating about exploration and geological understanding in Mongolia is the lack of it, with an estimation that only three quarters of the country has been mapped to a scale of 1:200,000.
The underdeveloped and general lack of infrastructure in the country won't present much of a problem for TVN Corporation at this exploration stage.
Boosting the coal possibilities even higher for Mongolian focused companies, the country has coal reserves estimated at over 150 billion tonnes.
