This week Blackham settled a rights issue which raised $35.9 million through the issue of 897.6 million shares and 448.8 million options.
The funds place Blackham in a strong position to execute on its free milling mine plan at the Matilda-Wiluna Gold Operation in Western Australia.
This plan includes exploration focused on growing free milling mine life.
Drilling to start next week
For this purpose, Blackham intends to start an initial drilling program next week.
Drilling will focus on growing free milling reserves through resource conversion and identifying additional mineralisation to maintain a free milling mine life greater than five years.
