   Further High Grade Gold-Copper Intercepts Reported from both Infill and 
Extension Drilling at the Hot Maden Project, north east Turkey 
 
   Mariana Resources Limited ('Mariana' or 'the Company'), the TSX.V and 
AIM (MARL) listed exploration and development company with projects in 
Turkey, South America, and Ivory Coast, is pleased to provide the 
following update on the ongoing diamond drill program at the high grade 
Hot Maden gold-copper project in NE Turkey. 
 
   Results are reported for a total of 12 infill and extension drill holes 
(HTD-75 and HTD-77 to HTD-87), with drill log data provided for a 
further 6 holes (HTD-88 to HTD-93) for which assays are pending.  The 
infill drilling in the Main Zone resource area is focused on section 
lines 4,542,225N, 4,542,175N, and 4,542,125N.  This forms part of a 
program designed to uniformally reduce drill hole spacings to 25m x 25m 
and to provide both detailed geotechnical data and metallurgical samples 
for mine development studies. Only limited drilling was completed in the 
"Ridge" area (southern limit of the Main Zone resource) and the New 
Southern Vein Field discovery (Figures 1 & 2) during this reporting 
period. 
 
   Highlights: 
 
 
   -- Exceptional  gold-copper (Au-Cu) grades continue to be returned from 
      drilling along two infill cross sections (4,542,125N and 4,542,225N; 
      Figures 3 & 4). This infill drilling continues to confirm the internal 
      continuity of Au-Cu mineralisation, including the high  grade, within the 
      Main Zone resource area. Best results include: 
 
   Infill Section 4,542,125N 
 
   HTD-85*:             60.6 m @ 82.2 g/t Au + 1.44% Cu from 209.4m 
downhole**. 
 
   This mineralised zone (approximate true width 35m) is the best 
intersection to date and includes the following subintervals: 
 
   209.4-229m: 19.6m @ 248 g/t Au + 1.90% Cu ("Ultra high grade zone") 
 
   229-248m: 19m @ 3.4 g/t Au + 1.21% Cu ("Medium grade") 
 
   248-270m: 22m @ 1.6 g/t Au + 1.19% ("Low grade zone") 
 
   HTD-82                 31m @ 17.0 g/t Au + 1.70% Cu from 266m downhole. 
 
   And 37.5m @ 2.1 g/t Au + 1.49% Cu from 317m downhole. 
 
   (approximate true width of Au-Cu zone 38m) 
 
   Infill Section 4,542,175N 
 
   HTD-78:                79.0m @ 14.3 g/t Au +1.59% Cu from 294m downhole. 
 
   Including 18.0m @ 55.1 g/t Au + 1.58% Cu from 296m downhole. 
 
   (approximate true width of Au-Cu zone 30m) 
 
   Infill Section 4,542,225N 
 
   HTD-77:                90m @ 22.6 g/t Au + 4.39% Cu from 96m downhole. 
 
   Including 11m @ 30.9 g/t Au + 6.30% Cu from 99m downhole. 
 
   (approximate true width of Au-Cu zone 76m) 
 
   HTD-75:                62m @ 11.7 g/t Au + 1.43% Cu from 276m downhole. 
 
   Including 2.0m @ 250 g/t Au + 6.50% Cu from 282m downhole. 
 
   And 44.0m @ 1.05 g/t Au +1.46% Cu from 334m downhole. 
 
   (approximate true width of Au-Cu zone 40m) 
 
 
   -- Potential for the discovery of a deep (>250m), possible fault offset 
      block of Main Zone-type mineralisation beneath the "Ridge" area (southern 
      limit of the Main Zone resource) continues to be tested, with drill hole 
      HTD-80 successfully intersecting multiple zones of high grade Au and Cu 
      mineralisation at depth. Host rocks to this mineralization are brecciated 
      andesites - similar to the host rocks in the Main Zone resource - which 
      lie immediately to the east of the dominant dacitic breccias.  Key 
      results include: 
 
   HTD-80:                4.5m @ 16.3 g/t Au + 1.90% Cu from 177.5m 
downhole. 
 
   5.0m @ 8.4 g/t Au + 1.30% Cu from 194.0m downhole. 
 
 
   -- Encouraging assays continue to be returned from limited discovery 
      drilling in the Southern Vein Field. Highlights include 3m @ 9.6 g/t Au + 
      1.73% Cu in HTD-79 and 10.5m @ 4.9 g/t Au + 1.9% Cu in HTD-81. 
 
   -- The Preliminary Economic Assessment (PEA) is in the process of being 
      finalised with an anticipated completion date expected early in the New 
      Year. 
 
   * Twin of HTD-71

   Chief Executive Officer Glen Parsons today commented: 
 
   "The continuity of these additional drill results at Hot Maden add 
further confidence in the main zone, with the 25m infill holes further 
support continuity of the high grade gold and copper mineralisation. 
These results all build into the Preliminary Feasibility Study model 
which is due for completion around mid next year, ultimately paving the 
way for mine development. 
 
   "Encouragingly the growth potential for the further extension to the 
main zone in of the offset block to the south as well as further 
interesting intercepts in the Sourthern Vein Field discovery area 
continues to be enhanced. 
 
   "Planned budgeted drilling for 2017 of 20,000m will be focussed on the 
areas that have  been delivering to date, as well as the untested area 
to the south, the "Russian Mining  area". 
 
   "The much anticipated PEA, although slightly delayed, is nearing 
completion and is expected to be delivered early in the New Year. I 
look forward to updating the market as soon as it is available." 
 
   Hot Maden Gold-Copper Project Update 
 
   Approximately 18,500 m of diamond drilling has been completed at the Hot 
Maden Project during 2016 (Figure 1 and 2).  Recent drilling activities 
have dominantly focused on: - 
 
 
   -- Infill drilling on 25m centres along sections 4,542,125N, 4,542,175N, and 
      4,542,225N. Selected holes have been utilised for geotechnical studies 
      and metallurgical testwork. 
 
 
   -- Deeper "step out" drilling to the east in the so-called "Ridge" area, 
      which is located at the current southern limit of the Main Zone resource, 
      and scout drilling of the Southern Vein Field (the northern extension of 
      the area mined by Russian interests pre-1923). 
 
 
   No significant work has yet been undertaken in the area of the former 
Russian mines (Figure 1). 
 
   Main Resource Area - Infill Drilling 
 
   Drilling advanced on 25m centres along infill cross sections 4,542,125N, 
4,542,175N and 4,542,225N, within the Main Zone resource area, with the 
program being designed to confirm internal continuity of the high-grade 
Au-Cu mineralisation. Certain holes were also selected for further 
geotechnical logging and metallurgical sampling. 
 
   On section 4,542,225N (Figure 3), HTD-77 returned high grade Au-Cu 
mineralisation (90m @ 22.6 g/t Au + 4.39% Cu from 96m downhole), from an 
upper massive sulphide (pyrite-chalcopyrite) zone and lower multiphase, 
chalcopyrite-pyrite-hematite-jasper-bearing breccia. The deeper hole 
HTD-75 returned two mineralised intervals (62m @ 11.7 g/t Au + 1.43% Cu 
from 276m downhole and 44m @ 1.0 g/t Au + 1.46% Cu from 344m downhole), 
both intercepts in multiphase, 
chalcopyrite-pyrite-hematite-jasper-bearing breccias. On section 
4,542,175N, drill hole HTD-78 also intersected an impressive 79m @ 14.3 
g/t Au +1.59% Cu from 294m downhole, with mineralisation being 
associated with multiphase, sulphide-bearing breccias. 
 
   Initial drilling along infill section 4,542,125N (Figure 4) included 
holes HTD-82 and HTD-85. Exceptional Au-Cu grades were returned from 
HTD-85, which intersected 60.6m of 82.2 g/t Au + 1.44% Cu from 209.4m 
downhole in multiphase, chalcopyrite-pyrite-hematite-jasper-bearing 
breccias. This mineralised interval includes an "Ultra high grade zone" 
of 19.6m @ 248.3 g/t Au + 1.90% Cu from 209.4m downhole, a "Medium 
grade" zone of 19m @ 3.4 g/t Au + 1.21% Cu for 229m downhole, and a "Low 
grade zone" of 22.0m @ 1.6 g/t Au + 1.19% Cu from 248m downhole.  This 
was drilled as a twin of HTD-71 for metallurgical sampling.  Drill hole 
HTD-82 intersected two main mineralised intervals: 31m @ 17.0 g/t Au + 
1.70% Cu from 266m downhole and 37.5m @ 2.1 g/t Au + 1.49% Cu from 317m 
downhole. 
 
   Main Resource Area - Extension Drilling ("Ridge" Area) 
 
   Two new drill holes (HTD-80 and HTD-86) were completed in the "Ridge" 
area, located at the southern limit of the Main Zone resource); HTD-80 
successfully intersected high grade Au-Cu mineralization at depth 
whereas HTD-86 remained in the adjacent zinc zone. High grade Au-Cu 
intervals returned from HTD-80 include: 4.5m @ 16.3 g/t Au + 1.90% Cu 
(177.5-182m), 1m @ 6.4 g/t Au + 0.30% Cu (189-190m), and 5m @ 8.4 g/t Au 
+ 1.30% Cu (194-199m). The target here continues to be a block of fault 
offset, Main Zone-type mineralisation located to the east of the 
existing drilling, and this hypothesis will be tested as a priority in 
future drilling. 
 
   Southern Vein Field / HTD 27 Area 
 
   Only two drill holes were completed in the Southern target area (the 
northern extension of the area mined by Russian interests prior to 1923) 
during this reporting period, with encouraging values continuing to be 
returned from quartz-sulphide veinlet/breccia zones hosted in dacitic 
breccias and volcanic rocks. Highlights from the current drilling 
include: 3m @ 9.6 g/t Au + 1.73% Cu (144-147m) and 9m @ 3.6 g/t Au + 
0.77% Cu (185-194m) in HTD-79, and 2m @ 5.4 g/t Au (128-130m) and 10.5m 
@ 4.9 g/t Au + 1.90% Cu (184.5-195m) in HTD-81.

   Quality Control and Assurance 
 
   Mineralised intervals presented in Table 1 are drill intersection widths 
and may not represent true widths of mineralisation. Drill core obtained 
from the diamond drill program was dominantly HQ-sized core with the 
remainder being PQ-sized core. All drill core was photographed and quick 
logged prior to sampling. Standard sampling protocol involved the 
halving of all drill core and sampling over generally 1 m intervals (in 
clearly mineralised sections) or 2 m intervals (elsewhere), with one 
half of the core being placed in a sealed sample bag and dispatched to 
the analytical laboratory for analysis. Samples have been analysed at 
ALS Laboratories' facility in Izmir, western Turkey. All samples have 
been analysed for gold using a 30g Fire Assay with AAS finish (or Screen 
Fire Assay for higher grade samples), in addition to a 32 element 
ICP-AES analysis of an aqua regia digest.  Samples in which ICP analyses 
returned greater than the maximum detection limit for the elements Ag 
(10 ppm), Cu (10,000 ppm), Fe (15%), Pb (10,000 ppm), and Zn (10,000 
ppm) were reanalysed using the AAS analytical technique, Standards and 
blanks were inserted in to the analytical sequence on the basis of one 
standard for every 20 samples, two blanks in every batch, and one 
duplicate every 40 samples. 
 
   Health, Safety, and Environment (HSE) 
 
   No HSE incidents have been reported during the current diamond drill 
program.

   About Mariana Resources 
 
   Mariana Resources Ltd is an AIM (MARL) and TSXV (MRA) quoted exploration 
and development company with an extensive portfolio of gold, silver and 
copper projects in South America and Turkey. 
 
   Mariana's most advanced asset is the Hot Maden gold-copper project in 
north east Turkey, which is a joint venture with its Turkish JV partner 
Lidya (30% Mariana and 70% Lidya) and rapidly advancing to development. 
An updated mineral resource estimate (detailed table below) of 3.43 Moz 
gold Equivalent (Indicated Category) and 0.09 Moz gold Equivalent 
(Inferred Category) (100% basis) in the main resource zone as well as a 
maiden 351,000 Moz gold Equivalent (Inferred Category) (100% basis) in 
the new southern discovery zone was reported for Hot Maden on July 25, 
2015. Elsewhere in Turkey, Mariana holds a 100% interest in the Ergama 
gold-copper project. 
 
   In southern Argentina, the Company's core gold-silver projects are Las 
Calandrias (100%), Sierra Blanca (100%), Los Cisnes (100%), Bozal 
(100%). These projects are part of a 160,000+ Ha land package in the 
Deseado Massif epithermal gold-silver district in mining-friendly Santa 
Cruz Province. 
 
   In Suriname, Mariana has a direct holding of 10.2% of the Nassau Gold 
project. The Nassau Gold Project is a 28,000 Ha exploration concession 
located approximately 125 km south east of the capital Paramaribo and 
immediately adjacent to Newmont Mining's 4.2Moz gold Merian project. 
 
   In Peru and Chile, Mariana is focusing on acquiring new opportunities 
which complement its current portfolio.

   *Au Equivalence (AuEq) calculated using a 100 day moving average of 
$US1,215/ounce for Au and $US2.13/pound for Cu as of May 29, 2016. No 
adjustment has been made for metallurgical recovery or net smelter 
return as these remain uncertain at this time. Based on grades and 
contained metal for Au and Cu, it is assumed that both commodities have 
reasonable potential to be economically extractable. 
 
 
   1. *-The formula used for Au equivalent grade is: AuEq g/t = Au + [(Cu % x 
      22.0462 x 2.13)/(1215/31.1035)] and assumes 100 % metallurgical recovery. 
 
   2. **-Au equivalent ounces are calculated by mulitplying Mineral Resource 
      tonnage by Au equivalent grade and converting for ounces. The formula 
      used for Au equivalent ounces is: AuEq Oz = [Tonnage x AuEq grade 
      (g/t)]/31.1035
