Velocity has an option agreement with Bulgarian partner, Gorubso Kardzhali A.D., to earn a 70% interest in the Nadezhda property, which includes the Makedontsi gold project with a geological resource registered on the Bulgarian State balance. Velocity can earn the interest by delivering a mineral resource estimate prepared under National Instrument 43-101. The Makedontsi deposit is located in southeast Bulgaria, approximately 10km by road from Gorubso’s modern CIL processing plant.
The deposit is open for expansion and requires systematic exploration to investigate its full potential and to deliver a mineral resource estimate prepared under NI 43-101. Concurrent with and building upon Velocity’s Rozino project prefeasibility activities, a program of modern integrated exploration is planned at Makedontsi in order to assess ‘blind’ mineralization amenable to open pit mining under a thin post mineralization limestone cover sequence.
The resource which is registered with the Ministry of Energy in Bulgaria is based on historical exploration, including approximately 250 drill holes (11,500m) and 5,000m of trenching completed by Gorubso.
Historical Resources for Makedontsi1, calculated by Gorubso using the Bulgarian classification system. Please review cautionary language below with respect to Historical Resources.
|Cut-off Grade (g/t gold)||Tonnes (Mt)||Gold Grade (g/t gold)||Contained Gold (ounces gold)||Bulgarian Resource Category|

Note 1. Historical resources at Makedontsi were calculated by Gorubso using the Bulgarian classification scheme, based on manual polygonal methods of resource classification. Resources were submitted to and accepted by the Bulgarian government, Dragiev H, 2013 "Mlechino Prospecting License, Geological Report at the Nadezhda Prospect, with Resource and Reserve Recalculations of ‘Au Ores’ at the Makedontsi, Dangovo and Kalina deposits”. Additional work will be required in order to verify historical resources and any potential additional resources and to complete a mineral resource estimate consistent with NI-43-101 standards of disclosure.
The Company cautions that it is not treating the historical resources as current mineral resources and/or mineral reserves. Historical resources are not consistent with the standards of disclosure defined by NI 43-101 and may not necessarily be consistent with CIM best practice with respect to reporting mineral resources and reserves. The historical resources are included because they are considered relevant by the Company as they confirm the presence of significant gold mineralization on the property which has not been fully delineated. The inclusion of historical resource estimations provides information as to the potential size and nature of the immediate exploration targets within the Makedontsi Property.
Mineralization is outcropping locally, but elsewhere the prospective sediments are covered by a thin veneer of post-mineral limestone estimated to range from 10 to 30m thickness. Consequently, the initial work program will focus on surface geochemistry and gradient array induced polarization (IP) surveys. The mineralization appears to be closely associated with silicification and it is expected that the planned IP geophysical survey will help locate prospective silicified zones if they exist below the limestone cover. Limited historical drilling indicates that locally mineralization does exist below the cover sequence.
In tandem with the above work Velocity plans to assess the reliability of historical drill results with angled heel-to-toe drilling (approximately 22 drill holes for an expected total of 1,000m). This initial phase will be completed on one drill section through the existing Bulgarian-registered historical resource area. The aim of the drill campaign is to verify mineralization intersected by historical drill holes, infill untested portions of the mineralized body, as well as increased understanding of geometry, continuity of mineralization, and geotechnical and hydrogeological aspects of the deposit.
Selection of rocks outcropping at Makedontsi. A. Low sulfidation epithermal (LSE) stockwork and silicification. B. Epithermal quartz banded vein. C. Composite LSE vein and silicification with abundant iron oxides after pyrite. D. Silicified polymictic breccia-conglomerate.
Discovery History at Makedontsi
The Makedontsi gold project was initially discovered in 1998 by Velocity’s VP Exploration as part of a regional surface geochemical survey (BLEG) undertaken by a subsidiary of Anglo American plc, Minorco SA. The discovery was interpreted by Minorco as “potentially epithermal gold occurrence hosted by terrigenous sediments in a favorable geologic-structural position similar to the epithermal Au mineralization at Perama Hill Deposit in Northern Greece”. As well as regional BLEG sampling, Minorco completed geological mapping, soil geochemistry, rock chip sampling and trenching.
A Bulgarian explorer (Gramex OOD) completed additional detailed mapping and drilled a single drill hole in 2001 intersecting firstname.lastname@example.org/tAu(incl. email@example.com/tAu). Gorubso acquired the project in 2005 and between 2007-2008 and 2012-2014 completed significant exploration including 5,115m of trenching and 252 drill holes for a total of 11,530m, and established a mineral resource estimate within the Bulgarian classification system.
