PROJECT SUMMARY


The Abujar Gold Project is located approximately 30km from the major regional city of Daloa in central western Côte D’Ivoire. It is close to good regional and local infrastructure to facilitate exploration and development being only 15km from nearest tarred road and grid power. The Abujar Gold Project is comprised of three contiguous tenements, Middle, South and North tenement, with a total land area of 1,114km2, of which less than 10% has been explored. It features an NNE‐orientated gold corridor over 70km striking across three tenements.

MINERAL RESOURCE

In April, Tietto announced a substantial increase in the Mineral Resource for its Abujar Gold Project in Cote D’Ivoire, with Inferred gold resources increasing by 146% across the Abujar‐ Gludehi (AG) and Abujar Pischon‐Golikro (APG) deposits, including a higher‐grade zone of gold mineralisation of 15.7Mt at 2.1g/t Au for 1.06 million ounces of gold between sections L15 and L29 over 1.4km at AG (Figure 1 – Oblique long section view of the AG deposit).


The updated Mineral Resource Estimate has seen Tietto more than double its gold resources in just over a year since its Initial Public Offering and listing on the ASX in January 2018, driven by an aggressive resource drilling program across three Abujar tenements.The AG resource increased by 114% in overall contained ounces, with 1.38Moz gold within 26.4Mt including the high‐grade section of 1.06Moz gold.The APG deposit, which is 5km south of AG, has a resource of 11.2Mt at 1.0g/t Au for 350,000oz gold.Tietto has defined Mineral Resources over only a small portion (6.9km) of a 70km mineralised corridor across three Abujar tenements and plans to complete more than 20,000m of diamond drilling using its own rigs in 2019, with plans to update the Abujar resource again in late 2019.Currently the two company owned drill rigs are drilling beneath untested massive artisanal workings immediately north and south of the AG resource and has also scheduled additional drilling to target the 5km strike length between the AG and APG deposits where it has discovered high‐grade shoots in previous drilling.

RESOURCE DEFINITION DRILLING

Prior to the April 2019 Resource Estimate update, Tietto embarked on 30,000m of combined reverse circulation (RC) and diamond (DD) resource definition drilling at the Abujar Project during 2018, aiming to substantially grow the 2016 Resource Inferred Estimate of 10.4Mt @ 2.1g/t Au for 703,600oz (JORC 2012) Mineral Resource inventory at Abujar through:Extending the existing AG (Abujar‐Gludehi) deposit along strike and to a depth of 300m vertical (180m vertical in the 2016 resources);Extending the existing Abujar‐Pischon (AP) deposit along strike and at depth; andDefining a Maiden JORC Mineral Resource at AGO (Abujar‐ Golikro) and testing the southernTietto drilled 124 new holes (RC, DD, RD and AC) for 14,725m at AG since its maiden resource estimate in December 2016. More than 18 sections have been drilled as access allowed and the new drilling has successfully extended the limits of known gold mineralisation.Results from drilling at the AG deposit identified broad high‐grade gold mineralisation, confirming the deposit’s strike continuity and extension.

Results from Abujar‐Gludehi (AG)

Step‐back RC holes drilled at the AG Deposit returned wide intervals of high‐grade gold mineralisation. Tietto has intersected gold mineralisation at AG over a 3km strike using RC, RCD and DD drilling, with mineralisation open down‐dip and along strike. Diamond drilling in particular returned impressive results of:

– ZDD028: 18m @ 11.72 g/t Au from 39m including 10m @ 20.69 g/t Au from 39m inc. 1m @ 194.93 g/t Au from 40m
– ZDD029: 14m @ 5.57 g/t Au from 91m including 6m @ 12.30 g/t Au from 91m inc. 1m @ 17.23 g/t Au from 91m, 1m @ 19.77 g/t Au from 92m, 1m @ 16.74 g/t Au from 94m and 1m @ 19.68 g/t Au from 96m

Other recently reported results include:

−    ZRC180A: 18m @ 2.30 g/t Au from 248m inc. 4m @ 5.77 g/t Au

Results from Abujar‐Pischon‐Golikro

Shallow aircore holes (AC) and step‐back diamond holes drilled at the Abujar‐Pischon‐Golikro (APG) Deposit returned wide intervals of high‐grade gold mineralisation, with the following outstanding intercepts:

Pischon (AP): ZDD014 (Diamond): 21m @ 2.80 g/t Au from 147m including: 4m @ 2.34 g/t Au from 147m including 1m @ 7.3g/t Au from 149m; and 7m at 6.84 g/t Au from 160m including 2m @ 21.22 g/t Au from 165m which includes 1m @26.54 g/t Au from 166mZAC02 (Aircore): 42m @ 1.06 g/t Au from 8m including: 16m @ 1.99 g/t Au from 20mwhich included 2m @ 12.98 g/t Au from 32m (hole ended in mineralisation).

Golikro (AGO):ZDD015 (Diamond): 5.5m @ 2.78 g/t Au from 185m including 1m @ 13.81 g/t AuZAC29 (Aircore): 26m @ 1.06 g/t Au from 26m including 4m @ 4.24 g/t Au from 46mAP (Pischon) is 7km south of the high‐grade AG deposit which hosts an Inferred JORC 2012 Mineral Resource of 1.04Mt @ 1.7g/t Au for 57,600oz gold defined in 2016 from reverse circulation drilling over 400m strike down to 90m vertical depth.Gold mineralisation at AP and AGO has been intersected over a 4km strike using RC, DD and AC drilling.

AP (Pischon) is 7km south of the high‐grade AG deposit which hosts an Inferred JORC 2012 Mineral Resource of 1.04Mt @ 1.7g/t Au for 57,600oz gold defined in 2016 from reverse circulation drilling over 400m strike down to 90m vertical depth.

Gold mineralisation at AP and AGO has been intersected over a 4km strike using RC, DD and AC drilling.

Ongoing DD Drilling and Next DD Holes

Tietto’s two DD rigs are currently drilling step-back holes at Line 28 and Line 29 where the Company recently reported broad high‐grade intersections of ZDD027 (Line29): 36m @ 4.40 g/t Au from 52m inc. 1m @ 103.17 g/t Au and 1m @ 33.45 g/t Au (ASX 12 March 2019).

Following completion of the current holes, the DD rigs will move to section Lines 30, 31 and 32 to test the strike extension of the gold mineralisation exposed by extensive surface artisanal workings, as shown in Figure 4. Tietto will continue to report drilling results over the coming weeks and months as the Company accelerates its drilling efforts with its existing two DD rigs and upcoming third DD rig.

Tietto expects to deliver another resource update to its current JORC Mineral Resource Estimates for the AG and APG (Abujar‐Pischon‐Golikro) deposits in late 2019.
