The initial £1.5mln is being raised via a share subscription deed, with new shares to be issued in tranches over an eighteen-month period.
To land the £45mln facility the company is entering into a placing subscription facility (PSF) which will similarly make funds available against equity tranches, over a 60 month period, to support future project expenditures.
The company said that the PSF increases its funding flexibility as current commercial activities at Thar Block VI continue.
"We believe that the execution of a funding facility with the Investors arranged by Riverfort on such a scale should prove to be a crucial element in unlocking the potential for Oracle's long term growth,” chief executive Naheed Memon said in a statement.
“We continue to strive to expedite progress at the Thar Block VI Project in Pakistan and are committed to achieving project milestones in as short a timeframe as practicable.
“In parallel with this, the board remains aware of additional potential compelling opportunities, with the potential for a quick turnaround, to which we believe we can apply our experience and ability to develop lucrative power and natural resource projects.”
"We welcome the new investment in the company and consider it to reinforce the confidence in the quality of Oracle's existing interests and growth strategy and deliver high returns for all stakeholders," he added.
