COMMENTARY

Mr. Isenor, stated, "I am extremely pleased that we have been able to acquire such a large and strategic land position in west Mali, an area we know well. I have just returned from Mali, where I visited all of the permits and many of the orpailleaur workings and I am extremely impressed with the potential of the area. These permits have impressive potential for the discovery of large gold deposits, as demonstrated by the many producing mines, new deposits and recent discoveries in the area. This is an area where we have excellent relationships and have had great success in the past.

Our exploration teams are in the field and doing an excellent job. Exploration to date has been positive and detailed gridding of soil and termite sampling is in progress in selected areas. Several sites of artisanal workings have also been identified and will be locations of immediate interest".
