possible reason for the spike

It is clear now why the share price has surged in the past 2 days.

I believe that the following comments from the article in the Australian dated 7 April has also had a positive impact.

Here is an extract from the article.

"With the exhaustion of Soviet bloc stockpiles of uranium, the growing nuclear power industry is facing real problems getting its hands on regular supplies
of yellowcake.

This quandary has been exacerbated by the fact that, because of the collapse of the uranium price in the 1980s and its persistence through the 1990s, very little exploration was done in that period. Ukraine, for example, has just announced that it plans to triple uranium production from the present 1000 tonnes a year so its nuclear power plants will be self-sufficient.

Expecting to be part of that is Perth-based Uran, which has picked up exploration projects in the former soviet republic."
