Ora Banda Mining Ltds (ASX:OBM) has received a positive definitive feasibility study (DFS) for the Davyhurst Gold Project in WA which managing director David Quinlivan told Proactive provided a solid case to re-start operations with a 5-year mine life.
The DFS released today confirms strong returns for a technically robust Davyhurst re-start.
Strong financial returns
As the culmination of an extensive 12-month work program to pursue a rapid and low-capex path to production, the DFS has confirmed that the project will generate strong cash flows and financial returns.
This will come from six distinct mining operations – Riverina, Missouri, Sand King, Waihi and Callion open pits and the Golden Eagle underground.
These six deposits that will feed the Davyhurt Processing Plant (within 50 kilometres of the plant) have estimated ore reserves of 6.1 million tonnes of ore grading 2.4 g/t for 460,000 ounces of contained gold over five years of mine life.
Opportunity to expand resource
Quinlivan said the company completed the DFS at a “very conservative” gold price of A$2,100 per ounce, while the price was approaching A$2,600.
“There is a 22 to 23% margin in the price we have used from where our benchmark case was.
“A lot of the higher grade areas from underground mines werent included in this first round so there is quite a lot of opportunity to expand this resource base and the reserve base over the course of the next five years.”
Pre production capital costs
“This is a low capital re-start – if someone was to build a new mining centre they would be looking at something north of $200 million to get it running by the time you put in access roads, airstrips, camp, offices and water supply bores.
“Our capital cost to get the whole thing restarted is quite small and modest in comparison to what it would be if you had to put a brand-new operation in.”
Underpinned by pre-existing infrastructure, including a conventional CIP process plant, the DFS estimates for the project show a pre-tax, free cashflow of A$175 million over a 5.2-year mine life using a A$2,100/ounce gold price.
Life of mine average annual gold production is 81,000 ounces with low C1 cost of A$1,427/ounce and all-in sustaining costs of A$1,566/ounce.
This includes an average estimated pre-tax annual free cash flows of A$33.6 million (A$68.8 million at A$2,550/ounce), following a 7 to 14 month payback period further leveraged by carried forward tax-losses of A$258 million.
Unlocking “significant value”
Quinlivan said the DFS confirmed that the existing infrastructure would enable Ora Banda to pursue a rapid path to production, with the first gold pour targeted for January 2021.
“The DFS also marks an important step in the companys evolution towards its ultimate objective of unlocking the significant value we believe is held in Ora Bandas strategic and prospective landholding.”
Quinlivan said funding was the companys next near-time priority, the board having approved the immediate commencement of the first phase of development activities, which would be funded by current cash reserves.
The company will consider financing the remaining pRead More – Source
