VANCOUVER, British Columbia, Dec. 17, 2021 -- Osino Resources Corp. (TSXV:OSI) (FSE:RSR1) (OTCQX:OSIIF) ("Osino" or "the Company") is pleased to provide an update on the ongoing development studies and project de-risking activities aimed at fast-tracking Osino's Twin Hills gold project in Namibia.

Twin Hills is a PEA-stage open pit gold development project with a mineral resource prepared in accordance with National Instrument 43-101 of 0.43Moz @ 1.00g/t in the Indicated category and 1.47Moz at 1.08g/t in the Inferred category at a cut-off grade of 0.5g/t. The Twin Hills maiden resource was released on April 12, 2021.

Heye Daun, Osino's Co-founder and President & CEO commented: "It is very pleasing to again be part of an exciting mine development project in Namibia. We have made significant progress in de-risking the project through the advancement of various technical studies in 2021. Much progress has been made with proving up or procuring the key utilities, namely power and water. Metallurgical variability testing has advanced to the point where we will soon be able to determine the optimal processing plant parameters, which will enable us to soon commence with feasibility studies. The ESIA and public participation process has also advanced substantially, thereby supporting a likely permitting decision that could set the project up for commencement of early works during the end of 2022."

Permitting Process and Environmental and Social Impact Assessment (ESIA)

Under Namibia's Environmental Management Act, the permitting system requires several steps toward approval of the mining license which the Company applied for in August 2021. These steps are regulated by Namibia's Environmental Management Act (2007) and the Minerals (Prospecting and Mining) Act (1992).

The most important of these steps are the completion and approval of the ESIA, including public consultation, and the compilation of an EMP. Once these are approved, the Namibian Ministry of Environment, Fisheries and Tourism (MEFT) issues an Environmental Clearance Certificate (ECC) which is generally the precursor to the granting of a mining license by the Ministry of Mines & Energy (MME).

There are a range of additional, secondary approvals, most of which are usually obtained subsequent to the granting of a mining license.

There are no prescribed timelines, but mining licenses are commonly granted after the completion of the ESIA process.

The following tasks have been completed to-date:

  • Project registration and Environmental Scoping Study (ESS) report submission
  • Baseline specialist study compilation
  • Public participation meetings and feedback documentation
  • EMP submission
  • Public review of ESS and EMP

Stakeholder engagement meetings were completed in September 2021 drawing key figures and representatives from local communities. The general commentary in the meetings was one of support for the project based on an expectation that the proposed mine would provide employment and stimulate the economy on a local as well as national level.

The next step of the approval process is now underway to produce an ESIA which will be reviewed by the MME who make recommendations to the MEFT to issue an ECC. The certificate is normally issued if no significant risk has been identified, and approval is normally expected within two to three months of submission of the ESIA.

The following permits are expected to be applied for during 2022:

  • Land clearing permit
  • Accessory works permit
  • Bulk fuel storage permit
  • Explosives storage and usage permit
  • Water extraction permit
  • Tailings waste disposal permit
  • Heritage permit

The process of applying for these secondary approvals will commence once the Mining License has been issued.

Mining and Optimisation

A phase one geotechnical program consisting of three preliminary holes was completed during 2021 which has guided the current pit design and slope angles. A follow up program consisting of four further holes in the Twin Hills Central pit and three holes in the previously untested Clouds pit will be drilled in Q1 2022 to provide a level of confidence to the pit design suitable for future work towards a Bankable Feasibility Study.

Plant Metallurgy Test Work

A fourth phase of metallurgical test work was started in the final quarter of 2021 designed to do variability testing suitable for future work towards a Bankable Feasibility Study. The test work is designed to target the optimal grind size and costs for a 4.5mtpa processing plant.

The program progressed according to schedule in Q4 2021 with the following items being completed:

  • Comminution
  • Thickening
  • Filtration
  • Gravity separation
  • Heap leach test work

The remaining program and test work in progress are:

  • Cyanide leaching targeting optimal grind size
  • Flotation concentrate and grind size variability test work

The initial results are looking positive and indicate that the processing parameters used thus far will be confirmed and will enable optimization of the processing layout. This metallurgical testwork program is expected to be completed in January 2022 and the results thereof will be integrated into an updated processing plant design to be published during Q1 2022.

Tailings Storage Facility

Design work has begun to develop a suitable tailings disposal strategy according to the Global Industry Standards for Tailings Management (GISTM) of August 2020. Geochemical Acid Rock Drainage (ARD) test work has indicated that the tailings material is not expected to be problematic due to its low acid generating potential and the high acid neutralizing potential of the host rock and regolith. As a result, it is likely that co-disposal and engineered lining will be optimal for the dry-stacked tailings deposition strategy. Test work and modelling of the geochemical results are ongoing and the updated strategy will be reflected in the next form of technical report.

Power Supply

Initial estimates from completed comminution test work, including crushing and milling tests, indicate a minimum power requirement of 16MW with a potential for further power up to 20MW. NamPower has performed a network analysis on the local grid and recommended developing a new dedicated 66kV feeder bay from the planned NamPower Erongo Substation. The new substation is to be constructed near the town of Karibib, which is situated approximately 15km southwest of the proposed mine site. An offer from NamPower to supply 16MVA via a 66kV overhead line to a metering substation at the mine site has been accepted by Osino, with the option to update the requirement before signing the final agreement based on the confirmed power demand calculations.

Discussions are now underway with NamPower to finalise the power supply agreement and determine options to fast track the development of the substation and transmission infrastructure.

Power supply cost analysis has determined grid power to be the most cost-effective source at an estimated NAD2.07/kWh over the life of mine taking both capital and operating costs into account. A cost-benefit analysis has shown the potential of implementing a hybrid system including solar power generation to reduce the cost to NAD1.73/kWh, and to supplement energy demand in a sustainable manner.

Mine Water Balance and Water Supply Options

Osino's mine water supply strategy is designed to develop a diversified mine water supply which will rely on three alternative supply options. 1) own supply from groundwater 2) additional potential supply from Khan River sand aquifers augmented through the construction of ground weirs and 3) supply from Namibia's national water utility, NamWater, through the national water grid.

The 4.5mtpa processing plant is estimated to require 5.5Mm3pa and filtration test work results at 63micron grind size indicate a 23% moisture content in the filter cake, resulting in a plant make-up water requirement of 1.3Mm3pa.

Field work during the year has been focused on advancing each of the strategies:

  • Water supply borehole drilling has successfully identified two different areas of groundwater along a marble syncline. The southern area has been drilled and pump tested with a proven sustainable yield of ~1Mm3pa. Drilling is currently targeting the northern limb and drill rig blow yields have already shown the potential for a further 0.5Mm3pa.
  • The Khan River ground weir study was progressed with a geophysical study confirming the potential for between 0.5Mm3 and 1Mm3 of water storage, and drilling will now confirm the aquifer dimensions.
  • As further de-risking, an application has been made to Namwater to secure a backup source of up to 1Mm3pa via a pipeline connection to Karibib. Under this scheme raw water would be sourced from the Swakoppoort dam supply.

Planned Project Schedule

Following a successful year of project development studies, Osino will continue to fast-track the development of the Twin Hills Gold Project. The company is working towards publishing a new technical report with an updated mineral resource estimate in Q2 2022 intended as a pre-feasibility study which is aiming to reflect improved project economics resulting from 1) project optimization 2) a larger mineral resource and 3) a substantial increase in processing plant capacity.

The next intended pre-feasibility study technical report is then also intended to be followed by a definitive, or bankable feasibility study and advancement of the constituent specialist studies to bankable level of detail by the end of Q3 of 2022. Based on that timeline, and subject to a positive bankable feasibility study, and project financing and permitting being in place by the end of Q3 2022, early works could commence towards the end of 2022. The Company presently only has a preliminary economic assessment technical report (the "PEA") entitled, "Amended and Restated Twin Hills Gold Project, Namibia, Preliminary Economic Assessment, National Instrument 43-101 Technical Report" dated effective July 14, 2021. The PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
