Gorubso-Kardzhali AD 30 % Indirect
Velocity Minerals Ltd. 70 % Indirect
In 2016, Gorubso won a competitive tender for exploration rights to the Tintyava Property. As part of an earnin option agreement, Velocity began exploration in July 2017 and in February 2018 the Tintyava Property was formally transferred from Gorubso to Tintyava Exploration EAD (“Tintyava Exploration”), the joint venture vehicle for Velocity and Gorubso. The participating interests of Velocity and Gorubso in the Tintyava joint venture are 70% and 30%, respectively, and both partners contribute pro rata to joint venture costs.

Deposit Type

  • Epithermal
  • Replacement
  • Vein / narrow vein


Summary:

Deposit Types
Rozino is a LSE gold deposit hosted within breccia and conglomerate Palaeogene sediments as disseminations, replacement and vein mineralization. The dominant mineralization strike is northwest, parallel to the regional extensional fault regime, with local mineralization development controlled by the intersection of steep structures sub-parallel to the bounding extensional faults, and gently dipping bedding.

Velocity’s exploration focussed on the dominant northwest trend of veins within the Palaeogene sediments. The veins appear to be controlled by steep structures interpreted to extend into the basement.

Drilling to date has not intersected significant gold mineralization within the basement. However, drilling has intersected crustiform gold and base-metal bearing, northwest striking LSE veins within the basement. These veins are generally narrow and rarely wider than 10 centimetres. The LSE hydrothermal fluids were confined within the impermeable basement and these non-reactive fluid pathways have very narrow alteration selvedges that are difficult to detect by drilling.

Upon reaching the basal unconformity the hydrothermal fluids would have de-pressurized and throttled boiling is the interpreted mechanism for gold deposition. The poorly consolidated breccia conglomerate sediments are interpreted to have been wet, further neutralizing the hydrothermal fluid, creating disseminated gold haloes peripheral to the boiling zones ........


Mining Methods

  • Truck & Shovel / Loader
  • Backfill


Summary:

The Rozino Gold Project comprises a single open pit utilizing standard mining equipment to selectively extract the ore over a nine year period (inclusive of a two year pre-stripping period). The pit will be mined in two phases utilizing a waste rock dumping and backfill strategy that provides a compact footprint. The mining is at extraction rates of up to 22,000 tpd using 90 tonne class excavators and 55 tonne capacity haul trucks. All material will require blasting. The schedule delivers higher grade ore directly to the plant in the initial five year period of the mine life at 5,000 tpd. Low-grade ore is stockpiled during this period and reclaimed for processing when the pit is exhausted. The resulting tailings from the low-grade ore are stored in the pit.

The mine plan has a pre-stripping period that is carefully balanced to produce waste rock for the construction of the water storage dam walls, the TMF embankment and ore stockpile pads. The pre-stripping period also delivers a small amount of ore that will enable the plant commissioning and start-up. Although the pre-stripping is over a two-year period, the first year entails mostly road building, clearing, grubbing and topsoil removal.

Mining will be by conventional open pit drill and blast followed by load and haul. The mining cycle commences with a grade control process that will utilizereverse circulation (RC) drilling on a 5 x 8 m pattern over 16 m of depth. The results of the grade control eval ........
