Tanami Gold NL commenced open pit mining at Coyote in 2006 and continued intermittently to 2008 when a portal was developed and underground mining commenced. Open pit mining briefly commenced again in 2009 before it was again halted. Underground production continued until June 2013 when the mine was placed on care and maintenance due to a significant fall in the gold price. Tanami Gold NL subsequently sold its combined Western Tanami Operation assets, which includes Coyote, to Northern Star in late 2017. Western Tanami Operation assets were acquired on 15 June 2022 by Black Cat Syndicate Limited.
As of January 16, 2023, Current Resources at Coyote Gold Operation of 645koz @ 5.5g/t Au are expected to grow with ongoing updates as drilling progresses. |

Summary:
Coyote and Bald Hill lie toward the western end of The Granites - Tanami Inlier, which is a highly deformed and metamorphosed Palaeoproterozoic block, approximately 250 km long and 100 km wide.
The basement was subjected to the Barramundi Orogeny prior to the deposition of the overlying sediments. Post-Barramundi rifting led to deposition of mafic volcanics, volcaniclastics and clastics and calc-silicatesof the McFarlane Peak Group. This was succeeded by the deposition of the Tanami Group in a passive marine environment.
The Coyote Deposit is hosted within folded turbidite clastic sediments of the Lower Proterozoic Killi Killi Beds. These sediments consist of dominantly well-sorted, coarse to very coarse greywackes, sandstones and siltstones, with variable but generally very weak carbonaceous content. A sub- marine fan setting, proximal to the sediment source was suggested, with sandstone thought to be deposited within sub-marine canyons eroding the clastic fan.
Quartz veining occurs in several different structural settings but the orebodies are generally associated with finely disseminated or coarsely crystallised arsenopyrite mineralisation with only traces of other sulphides or of carbonates.
Parallel thrust faults that ramp through the bedding, such as the Gonzalez Thrust Zone, occur on both the south and north limbs but are more common on the south limb. Thicker (10 to 30 centimetres (cm)) parallel quartz veins form as a result ........

Summary:
Bald Hill is comprised of two small open pits (Kookaburra and Sandpiper), one rehabilitated pit (Osprey), a WRL, low-grade and mineralised waste stockpiles, ROM pads, an evaporation dam, a haul road to Coyote and basic mining support infrastructure.
Current open pit resources have been mined out, although there is still a resource of approximately 600,000 t of ore at approximately 6 g/t remaining under the pits that has underground potential. Modifications to the mill at Coyote are required to process this resource, as there are metallurgical recovery issues related to grind of the slightly refractory ore.
The underground workings provide access to further resource base with underground development outlined in mine planning at the time Coyote went into Care and maintenance.
