Results from a further 51 holes to be returned in June and July for completion of an updated Mineral Resource Estimate planned for the September Quarter;
-
A diamond drill program for geotechnical, metallurgical and hydrogeological assessment as part of an open pit mining feasibility study to commence in July.
Yandal Resources Ltd (ASX: YRL , “Yandal Resources” or the “Company”) is pleased to report further 1m sample assay results from reverse circulation (“RC”) drilling at the Flushing Meadows prospect within the Ironstone Well gold project located in the highly prospective Yandal Greenstone Belt in Western Australia.
The drilling was completed in May 2020 to expand and upgrade the initial Mineral Resource Estimate[1] (“MRE”) and to support open pit mine development activities at the prospect. Flushing Meadows is located 60km south-east of the mining town of Wiluna and is within close proximity to a number of gold development projects and operating mines (Figure 1).
Gold assay results from 29 angled RC holes for 2,189m are reported above a 0.50g/t Au lower cut-off grade in Table 1 with important intervals highlighted in Figure 2.
Yandal Resources’ Managing Director; Mr Lorry Hughes commented:
“The aim of this program is to reduce the distance between drill holes in areas containing mineralisation that have potential to be included in an optimised open pit design. Reducing the distance between mineralised intervals coupled with consistent QA/QC sampling programs should improve confidence in the updated MRE when completed.
The upcoming diamond drill program will provide important information for the determination of key engineering parameters to be used in the pit design and the economic assessment of the deposit”.

Feasibility Study Activities
The Feasibility Study, Mining Proposal and Mine Closure Plan, contemplate construction of a conventional open pit (only) mining operation with road haulage to third party processing facilities conducted by contractors and managed by Yandal Resources. Work streams are to be conducted by a combination of Yandal Resources personnel and independent resource industry consultants.
Geology and Mineral Resource Estimates
The current JORC Code 2012 MRE for the Flushing Meadows deposit (Tables 1 and 2) was compiled in September 2019 by BM Geological Services Pty Ltd (“BMGS”) with the geological database supplied by Yandal Resources. An upgraded MRE is planned for completion in September Quarter 2020 and will include all prior drilling intended to upgrade a portion of Inferred Resources to Indicated Resources.
A close spaced RC drilling program will be designed to reduce assay data density in a number of key mineralised areas of the MRE both above and below the standing ground water table as part of ongoing QA/QC programs. The aim of the programs is to improve confidence in modelling parameters, grade estimation and grade continuity.
Table 1 – September 2019 Flushing Meadows Mineral Resource Estimate (0.5g/t Au Lower Grade Cut-off) – Refer to Yandal Resources Ltd ASX announcement dated 25 September 2019 for full details.

Geotechnical and Hydrogeological Study
Independent consultants have been awarded contracts for the completion of suitable geotechnical, groundwater and surface water studies to support the Feasibility Study and a number of work programs have commenced. Diamond drilling is planned to begin in the September Quarter to provide high quality geological and geotechnical data to assist with open pit mine design. Four angled HQ triple tube diamond core holes (470m) will be completed with a range of depth from 100-130m. The planned collar locations are shown in Figure 2.
The diamond drill holes are planned to be equipped as water monitoring bores to support hydrogeological assessment upon completion of coring activities.

Ore Processing
In the December Quarter 2019, the Company released the results of early stage metallurgical test work undertaken by ALS Metallurgical laboratories in Balcatta, Western Australia[1] . Results from composited RC drill hole samples representing oxide material above 80m vertical depth at a grind size of 106 microns, returned an average of 94.1% gold recovery from conventional gravity and cyanide leach processing.
A transitional RC drill sample from between 89-94m vertical depth ground to 75 microns returned 84% recovery with gold associated with ~4% pyrite and minor arsenopyrite.
The gravity and cyanide gold recoveries from mineralised oxide and transitional material at the grind sizes tested are acceptable for existing third party carbon-in-leach (“CIL”) processing plants in the region. Additional test work suitable for inclusion in the Feasibility Study will be completed on diamond core samples and be available in the June Quarter 2020.
During the December 2019 and March 2020 Quarters, additional metallurgical test work was conducted on three mineralised samples from primary zones (128 - 136m down hole depth) in order to determine if significant exploration at depth beneath the planned open pit is warranted in the short term.
Further metallurgical assessment is planned to be conducted on the drill core once geotechnical logging and sampling is complete.
Pit Optimisation and Mine Design
Pit optimisation studies, mine design and Ore Reserve Estimation are to be completed by Intermine Engineering Consultants and utilising information supplied by independent technical consultants, mining and haulage contractors and Yandal Resources.
Environmental, Permitting and Stakeholder Engagement
An initial flora and fauna survey was completed by Botanica Consulting in 2019, and they have been retained to complete Mining Proposal, Mine Closure Plan and Clearing Permit applications for the project.
The majority of the current MRE is within granted Mining Lease M53/1093, Yandal Resources has applied for a new Mining Lease M53/1108 adjoining M53/1093 to the north west along strike and within Exploration Licence E53/1963 (Figure 2).
The Flushing Meadows prospect is located within the Kultju (Aboriginal Corporation) RNTBC (“Kultju”), Kultju Determination. The Kultju Aboriginal Corporation is an incorporated body under the Corporations (Aboriginal and Torres Strait Islander) Act 2006 (Cth) and is the Registered Native Title Body Corporate determined to hold native title rights and interests on trust for the Kultju Native Title Holders. Central Desert Native Title Services Limited (“Central Desert”) has been authorised by Kultju Aboriginal Corporation to act as its agent in regards to land access negotiations and agreements.
The Company is in the early stages of engagement with Central Desert, the Shire of Wiluna and the Department of Mines, Industry, Regulation and Safety to work towards the completion of all statutory approvals to mine.
