Tlamino Gold Project

100% Medgold Owned Project in Serbia

The Tlamino Project comprises a block of two contiguous licences granted in November 2016, Donje Tlamino and Surlica-Dukat, totalling 192 square km. The project is located in the southeast of the country, bordering Macedonia and Bulgaria. The Donje Tlamino licence hosts two main targets, Barje and Liska. The Surlica-Dukat licence includes the Karamanica target.

The licences are located in the Serbo-Macedonian Massif (“SMM”), a belt of greenschist to amphibolite metamorphic facies, Silurian-aged mid-crustal rocks that runs through Serbia along a north-south axis, extending southwards through Macedonia and Bulgaria and into Greece. In Serbia, the SMM lies west and sub-parallel to the upper Cretaceous Timok Belt, which hosts a number of copper-gold porphyry-epithermal deposits. The SMM is under-explored when compared to the Timok Belt, having seen lead and zinc exploration work by the Yugoslav government and Yugoslav state companies from the 1950s to the 1970s, but far less exploration post-2000. In Greece, the SMM hosts several well-known gold deposits including the Skouries high-grade Au-Cu porphyry and the Olympias Au-rich, polymetallic carbonate replacement deposit, both owned by Eldorado Gold.

Medgold’s licences are located along the Macedonian and Bulgarian borders, approximately 40 km southeast of the city of Vranje, in southeast Serbia. They cover areas of Paleozoic metasediments, including calcareous schists and marbles, which have been intruded by a series of Oligo-Miocence aged porphyritic felsic hypabyssal intrusives, volcano-clastics and dykes, and locally covered with recent alluvial sediments (conglomerates). Contact zones between the intrusive rocks and favourable country rock are responsible for the known base and precious metal showings within the licence areas. Fairly extensive exploration was completed by the Yugoslav government and Yugoslav state companies in the 1950s to 1970s for lead and zinc. Precious metals are often referenced in the historical and archival exploration documentation, but were not the focus of any exploration efforts, nor systematically documented. Today, it is recognized that these mineralized systems are structurally controlled, intermediate sulphidation epithermal in nature, and their lack of historical precious metal exploration presents significant exploration upside for Medgold.

The Tlamino Gold Project includes two historical showings: Liska and Barje. Both showings are associated with a regional east-west striking detachment fault, which in the vicinity of these showings has been overlain by conglomerates. Mineralization is located at the contact of the basement metamorphic rocks and the base of the conglomerate cover. Liska, located approximately 1.5 km to the southwest of Barje, was drilled in the 1950s and 1970s by Yugoslav state companies, and a lensoid-shaped mineralized volume of rock with 1-2 wt.% combined Pb-Zn was found to strike NE towards Barje. The mineralization at Liska is located at the base of the Miocene conglomerate and parallel to the slope of the detachment fault. Liska was found to contain little precious metals. At Barje, base metal contents are lower, but precious metals are found in much higher concentrations. The area between the two showings is overlain by a thin conglomerate cover likely in the range of 50 – 100 metres in thickness, and Medgold considers the exploration potential under the conglomerate, between the two showings, to be excellent.

It was recognised that the Liska-Barje prospect, is hosted by tectonic breccia developed along a regionally extensive, low-angle detachment fault.

The lead-zinc mineralization, especially the gold- and silver-rich zone at Barje is hosted by gneissic rocks immediately beneath Eocene conglomerate and intercalated sandstone. Inspection of the drill core recovered by Dundee Precious Metals group at Barje suggests that the fragmental host rock is a tectonic breccia formed along the Crnook detachment fault during the final brittle stages of core complex exhumation (Sillitoe, 2016). The observed breccia contains clasts of muscovite-rich gneissic granite, metamorphic quartz, amphibolite and perhaps other rocks, and is underlain by non-brecciated amphibolite, representing the top of the Crnook dome. The fragmental host rock to the lead-zinc mineralization at the nearby Liska prospect is likely to be a similar tectonic breccia.

Mineralization at Liska and Barje occurs as irregular veinlets and patches hosted in tectonic breccia which is partly silicified and sericitised. The sulphides are mostly dominated by pyrite, arsenopyrite, galena and sphalerite.

The Barje Zone is host to a large outcrop of intense brecciation and mineralization. The best results from surface channel sampling returned 84 m of 5.60 g/t Au and 105 g/t Ag (see Company press release on July 18, 2017). In 2017, an IP-Resistivity geophysical program undertaken by Medgold at the Barje Zone identified a large chargeability anomaly measuring approximately 1,000 m east-west by 400 m north-south, as well as a second-order anomaly with a NNE-axis overlying the Barje outcrop. The outcrop channel sampling and geophysical survey results were highly encouraging, and a first phase diamond drilling program was designed to test for the presence of a large shallow mineralized body associated with the Barje outcrop and chargeability anomaly.

In May 2018 Medgold commenced its inaugural drill program at the Barje zone, aiming to test the up-dip continuity of mineralization to the north-north of the main Barje outcrop, and to test mineralization potentially associated with the large-scale chargeability anomaly. Assays have been received for the four holes, and have returned broad intersections of near-surface gold and silver mineralization:

  • BAR001:  30.82 m of 2.06 g/t Au and 54.7 g/t Ag from 2.38 m to 33.20 m
  • BAR002:  34.65 m of 3.11 g/t Au and 27.5 g/t Ag, from 13.35 m to 48.00 m (including 2.00 m of 23.88 g/t Au and 340 g/t Ag)
  • BAR003: 26.10 m  @ 2.44 g/t Au and 219 g/t Ag, from 2.0 m to 28.1 m (including 6.0 m of 4.20 g/t Au and 754 g/t Ag from 3.6 m to 9.6 m)
  • BAR004: 22.10 of 1.83 g/t Au and 109 g/t Ag, from 2.2 m to 24.3 m


BAR001 is collared approximately 70 m north of the Barje outcrop (which assayed up to 84 m of 5.6 g/t Au and 105 g/t Ag in surface channel samples; see Company news release of July 18, 2017), and was designed to confirm that mineralization extends in a third dimension along a north-northeast axis from the outcrop. BAR002 is collared approximately 300 m north-northeast of the Barje outcrop and was designed as an up-dip step-out from the outcrop and BAR001. BAR003 and BAR004 are both collared on the same pad as BAR001. All drill holes have successfully intersected significant near-surface mineralization; a summary of assay results is given in Table 1, and hole locations are given in Table 2. Drill collar location map and schematic cross-section is shown below. The results to date support Medgold’s interpretation of the Barje mineralization as being associated with a flat-lying regional detachment fault.

Project History

Medgold Resources Corp. TSX.V: MED

The Tlamino Project area was explored in the latter half of the 20th century by the Yugoslav national geological survey and by Yugoslav state exploration companies for their lead and zinc potential. Liska returned higher base metal values and was explored more comprehensively, but it appears neither showing was systematically evaluated for gold and silver. The lead-zinc mineralization at Liska was drilled by Yugoslav state companies in the 1960s and 1970s. The mineralization at Liska was found to consist of an elongate lensoid body approximately 30 m in thickness, located at the base of the conglomerate and trending to the NNE towards the Barje showing.

In the mid 2000s, Avala Resources (now Dundee Precious Metals; DPM) explored the area and completed multiple geochemical surveys and rock chip sampling and trenching near Barje.

A total of 4 diamond drill holes, for 831.2 m, were completed by Avala Resources in 2007 in the vicinity of the Barje showing. Medgold recently acquired a dataset from DPM, containing regional exploration data covering our recently granted licences as well as the drilling data from Barje.

One drill hole targeted the Barje outcrop, but Medgold considers that it was collared in a down-faulted block below Barje and consequently missed the Barje mineralization. A further three drill holes were completed by DPM, located to the east of the Barje outcrop. These intersected sequences of tectonic breccias considered by Medgold to represent the Crnook detachment fault, as at Barje, but considered to be a parallel detachment zone below the hangingwall zone typified by the Barje outcrop and which hosts the high-grade mineralization.



In June 2016, Medgold completed a $1.5 million private placement to Fortuna Silver Mines (“Fortuna”) by way of the issuance of 10.0 million units at $0.15 per unit.  Each unit consists of one common share and one warrant $0.15 for one year from closing. Using the placement funds, Fortuna and Medgold commenced with a Strategic Alliance, to generate new gold and silver targets in Serbia. The generative exploration work focused on the Oligo-Miocene igneous belt of Central and Southern Serbia. In addition, Medgold granted Fortuna the option to enter into an option agreement to earn up to a 70% interest of a Selected Project, by spending US $8 million in qualifying expenditures over 6 years.

In late 2016, Medgold received its first exploration licences in Serbia, resulting from target generation work, and which included the Donje Tlamino licence. Immediately following the licence issuance, Medgold undertook a program of channel-chip sampling at the Barje prospect, located within the Donje Tlamino licence, and yielded a best result of 40 m of 8.32 g/t Au and 193 g/t Ag.

In March 2017, following the completion of 12 months of generative work, Fortuna elected to option the Tlamino Project (comprised of the Donje Tlamino and Surlica-Dukat licences), and thus has the right to incur expenditures of US$3.0 million to acquire 51% of the project within 3 years, and have the second option to earn a further 19% over 3 years, by spending US $5 million and completing a Preliminary Economic Assessment (PEA).

In addition, Fortuna exercised their warrants in February 2017, for total proceeds of $1.5 million, and secured 24% of the capital of Medgold. The proceeds were used within the Strategic Alliance, for a further 12 months, aiming to generate new projects in Central and Southern Serbia. Fortuna was granted the right to option a second project, on the same terms of the first, whereby they can earn up to a 70% interest of a second Selected Project, by spending US $8 million in qualifying expenditures over 6 years.



Medgold has completed three phases of saw-cut surface channel samples over the outcrop at Barje.

Results from the first two phases of sampling (CH_BAR_01-11) creates a contiguous channel interval of 84 metres at 5.6 g/t Au and 105.2 g/t Ag.

The third phase of channel sampling (CH_BAR_12-14) was from an adit at Barje was excavated by a Yugoslav state company in the 1950s as part of their regional exploration for Pb-Zn mineralization. The composited grade of the adit was 2.20 g/t Au and 88 g/t Ag, with 36 out of 52 samples assaying greater than 1 g/t Au, a minimum grade of 0.49 g/t Au, and a maximum grade of 25.3 g/t Au.

From these three phases of channel sampling a total of 298 samples were collected, which includes 41 Quality Assurance samples (blanks, standards and field duplicate).

Following a detailed structural interpretation of the geology between the Barje and Liska prospects, the Company has completed an Induced Polarization / Resistivity (IP-Res) geophysical study which has identified a high chargeability anomaly which extends to the west of the Barje outcrop under cover for over 1 kilometre.

The objective of the 39 line-kilometre IP-Resistivity program was to analyse an area covering 4 square kilometres, focusing on the Barje-Liska prospects, for near-surface sulphide-rich mineralization.  The program commenced at the Liska prospect, which has been historically drill-tested for Pb-Zn mineralization by the former Yugoslav state companies in the 1950s and 1970s, and results from both the drilling and IP-Resistivity survey support the geological model of relatively flat-lying mineralization at the contact of the basement rocks and the overlying schists.

At Barje, located 1.5 kilometres to the northeast of Liska, a large high-chargeability anomaly was identified just west of the Barje outcrop.  The anomaly measures approximately 1 kilometre east to west and approximately 400 metres north to south.  The southern limit of the anomaly appears to track a large-scale regional detachment fault, which has been assumed to be a principal control on mineralization at both Barje and Liska, and its surface expression trends east-west.  The anomaly continues northwards, which is considered to be the northerly extension of the same detachment fault, but beneath cover and steepening topography.  Interestingly, the high-grade saw-cut channel sampling completed at the main Barje outcrop is located on the eastern flank of the chargeability anomaly.  At this stage, it is unknown whether the chargeability anomaly is directly related to gold mineralization; however, it is clear that the surface rocks exposed in the area of the chargeability anomaly consist of schists which display similar alteration and mineralization as seen in the schist stratigraphically overlying the mineralization at Barje. The Barje outcrop itself is observed in the chargeability data as a weaker NNE trending corridor; this also constitutes an exploration target to be followed up.


The Karamanica prospect is located in the Surlica-Dukat Licence, and is located approximately 8 km to the west of Barje, The Karamanica target is located on the southwestern margin of the Crnook dome, hosted by upper crustal schists of the Vlasina unit. Karamanica is dominated by a series of large-scale northwest-trending faults, which cut packages of schists, highly deformed calc-schists, and quartz-feldspar porphyry dykes.

Medgold has completed a program of detailed mapping and rock sampling, plus grid-soil sampling,at Karamanica, with samples collected on a 200m by 50m grid. Initial reconnaissance work has identified strongly altered and brecciated felsic volcanics, locally significant calcareous schists, graphitic schists, limestones, and zones of galena-sphalerite and pyrite-silica mineralization. Despite poor outcrop exposure in the area, a total of 129 rock chip samples have been collected to date on the prospect, with 14 returning assays greater than 1 g/t Au. The rock chip samples returned highs of 11.1 g/t Au, 7.1 g/t Au and 5.5 g/t Au, typically associated with the pyrite-silica mineralization.

Assays from a recent soil sampling campaign define two large anomalies with consistent soil geochemistry with > 50 ppb Au-in-soil, within which are significant linear zones of >100 ppb Au. The highly anomalous soil geochemistry and favourable lithological units and fault structures demonstrate the high prospectivity of the Karamanica Prospect.

The first soil anomaly extends over an area of approximately 1 km by 1 km, and is associated with a regional northwest-trending fault, which offsets felsic volcanic rocks from basement schists and calcareous schists. The second, located approximately 1 km north of the first anomaly, extends over approximately 800 m by 600 m. Mineralization appears to be associated with of the presence of disseminated to massive sulphides within the host calcareous schists. The same fault structure hosts blind massive carbonate-replacement Pb-Zn-Ag mineralization.
