Crepulje is a zinc-lead exploration project located approximately 17km west of the town of Mitrovica in northwestern Kosovo. It is approximately 20 kilometres to the west of the most prolific mining area in the region, the Trepça Belt, a series of historically mined deposits that extends for some 80 kilometres in northern and northeastern Kosovo and is considered to be within the same geologic belt. The property consists of an exploration license of 9.82 square kilometres.

Crepulje was originally investigated by the Yugoslav State Trepça Company in the 1950’s. In 2007, an Exploration License, which at that time covered an area of 59.1 square kilometres , was awarded to Lydian International Limited (Lydian) over the Crepulje prospect. Altair obtained the license covering Crepulje by purchasing 90% of the ownership shares of A.GJ.A SH.P.K. (AGJA), a limited corporation existing under Kosovo law. AGJA holds the 100% of the exploration license covering the Crepulje property.

Historical soil sampling defined a north-south oriented zone 5km long by 200-500m wide  with continuous zinc and patchy lead anomalies. Four adits and six trenches were  excavated  around 1974. Several of these encountered zones of gossanous oxide mineralization.  Trenching demonstrated that zinc-rich mineralized zones occur as veins, fractures and cavity fillings ,and as breccia patches in a limestone karst terrane. Soil sampling  by Lydian in September 2007 confirmed the previously reported Yugoslav geochemical anomalies, with some exceptionally elevated values. Lydian also reopened the historic trenches and completed a program of seven diamond drill holes in 2008.

Current exploration by Altair has focused on  numerous high-grade zinc and lead occurrences  within a target zone measuring 500 metres by 300 m.  Several surface trenches here exhibit high grade zinc-lead mineralization zones running between 17 to 35 per cent zinc plus lead over 2 to 4 m widths within broader mineralized zones. These zones lie within the pronounced zinc and lead geochemical anomaly defined by earlier work.

A field program in 2016  by Altair  re-excavated  and extended three existing trenches and completed five new trenches. That work not only confirmed the high lead and zinc values reported during previous work but also discovered high-grade mineralization in four new areas. These new discoveries extended the zone of high-grade lead-zinc mineralization by an additional 300 metres to 450 metres.

Results from the five new trenches (No. 8 through No. 12) ,and one addition sample (No. 19) collected from a newly discovered outcrop,  are presented in the following table:

Portions of trenches 1, 2 and 3, which were originally excavated in 1974, were re-opened, deepened and widened. Nine samples were collected during the 2016 program with results presented in the following table:

In 2017 Altair is undertaking a diamond drilling program to test for extensions of high grade zinc-lead-silver mineralization encountered in previous trenching and drilling of the original mineralization. Drilling will also target gravity anomalies outlined by a gravity survey. The zone of high grade zinc-lead mineralization in Trench 2-1a was extended down dip in hole CRP008 which intersected excellent zinc values as shown in the following table:
