Saracen Managing Director Raleigh Finlayson said the latest results highlighted the significant growth potential at the Company's existing assets.
"Our organic growth strategy continues to deliver exceptional returns on our investment by any measure," he said. "There is still immense potential to grow production and mine life at our assets, which also allows us to capitalise on our existing infrastructure. This combination of extremely low discovery costs and access to existing infrastructure ensures we generate outstanding returns on our capital, which is our overall objective."
More growth in FY20
Western Australian gold miner Saracen Mineral Holdings (ASX: SAR) is pleased to report another round of strong drilling results.
Saracen's increased exploration spend in recent years has past three years (after mining depletion) to a record 3.3Moz increase of 800,000oz despite 330,000oz mining depletion.

Carosue Dam Operations - Drilling update
Karari - Dervish underground
The Karari - Dervish underground mine comprises two sister deposits, Karari and Dervish, adjacent to the Carouse Dam mill.
Karari drilling has focused on infill grade control following a significant increase in Ore Reserves at 30 June 2019. Drilling has continued with two underground rigs from the 1940 and 1916 drill drives. Multiple thick high grade results have confirmed the increasing grade profile with depth.
Significant results include 51m @ 8.5g/t, 33m @ 7.5g/t and 24m @ 14.3g/t. The high grade shoots remain open at depth and will be tested further during FY20.
Figure 3 - Karari Long Section, New Drill Results (Karari-Dervish mine)
Drilling will revert to extensional exploration and Resource definition early in the March quarter 2020, when the new 1805 drill drive is fully developed. This will be located 135m below the existing drill platform to facilitate the next phase of Reserve growth, weighted to FY21. This will be counterbalanced by enhanced contributions in FY20 from other areas within the portfolio.
Below is a table of significant Karari infill intercepts:

At the sister Dervish deposit, drilling in the south has continued to define the thick high grade shoot bound by the Osman Fault, with strong results including 17.0m @ 4.0g/t, 26.1m @ 3.5g/t and 13.9m @ 3.6g/t.
Drilling in the north similarly has defined thick high grade mineralisation within the current Ore Reserve. Significant new results include 20.3m @ 4.6g/t, 20.7m @ 4.5g/t and 10.2m @ 7.9 g/t.
Figure 4 - Dervish Long Section, New Drill Results (Karari-Dervish mine)
Extensional drilling from the existing drill platform is largely complete, with a hiatus planned in the June half 2020 whilst drilling capacity is deployed to Deep South to commence infill drilling ahead of ore development.
The next extensional exploration and Resource definition program at Dervish will commence when a new drill drive is established at depth, anticipated late in the June quarter 2020.

Thunderbox Operations - Drilling update
Thunderbox underground
Recent drilling has been testing the margins of the mineralisation to optimise the extents of the Ore Reserve ahead of underground mining. The latest results have continued to demonstrate the consistent and persistent nature of the Thunderbox mineralisation, boding well for future underground stoping.
Significant new A Zone underground results include 89m @ 2.0g/t and 72m @ 2.4 g/t.
Figure 5 - Thunderbox Long Section, New Drill Results
Thunderbox D Zone
A small surface RC program has been completed in the D Zone to increase the definition of the high grade shoot. Previous drilling highlighted the prominence of the shoot with the new drilling adding further confidence.
Significant new D Zone open pit results include 86m @ 1.7g/t and 72m @ 2.4 g/t.

Otto Bore
Extensional infill RC drilling has resumed at Otto Bore following the successful maiden Ore Reserve of 950kt at 2.0g/t for 60,000 ounces at 30 June 2019. The extensional drilling has focused on further defining the high grade shoots proximal to the Ore Reserve.
The recent drilling has further demonstrated the growth potential of the project with some impressive results being returned.
Significant new Otto Bore results include 8m @ 27.2g/t, 13m @ 7.8g/t and 16m @ 6.1 g/t.
Figure 6 - Otto Bore Long Section, New Drill Results
The recent program is only partially complete, with drilling set to resume when the Thunderbox D Zone program is finished later this month. The program will then focus on testing north of the Ore Reserve.

Regional Exploration - Update
Atbara (Carosue Dam Corridor)
Drilling along the highly prospective Carosue Dam Corridor has delivered early success, with a significant discovery at Atbara (announced in November 2018), only 4km north of the mill.
Broad 160m x 160m framework drilling has recently been completed, aimed at understanding the size of the system. A large system has been identified, with the majority of the mineralisation occupying a strike length of 860m between two major post mineralisation Proterozoic dykes. The system remains open at depth.
Significant new framework results include 122m @ 1.1g/t and 89m @ 1.1 g/t.
Figure 7 - Atbara Long Section, New Drill Results
Following completion of the framework drilling, a tight spaced 20m x 20m program has commenced. This program will assess the close space variability and continuity of the mineralisation, and assist in optimising the drill spacing required to define and build a future Mineral Resource estimate.
Detailed re-logging of the copper-molybdenum minerals with respect to gold has not identified any direct correlations, indicating the gold and copper-molybdenum may be from separate mineralising events. Recently over 15,000 pulp samples have been submitted for copper and molybdenum assay to determine if the copper-molybdenum is a key element of the overall system.

Carosue Dam Seismic Project
Completion of the 3D seismic survey data processing is anticipated in the current December quarter.
The high-resolution fully nodal acquisition recorded 263 million traces of seismic data over 50km2 including Karari, Dervish and Atbara. This is the highest resolution hard rock survey in Australia and the second largest by area to date. The majority of the survey has a 400-fold cover in a 7.5m x 7.5m bin size. Each depth slice of the final 3D cube will have about 1 million data points. Early indications suggest resolution of geological features in the 3D cube will be excellent.
Early review of the processed data confirms the high geological resolution that has been mapped by the survey. The fine detail that will be resolved will facilitate the construction of a highly definitive 3D geology model. This model will be extremely valuable when defining new drilling targets proximal to the existing mines and along the Carosue Dam corridor north to Atbara.

Mt Celia
Broad pattern drilling (900m x 100m) has continued to progress south along the previously unexplored corridor proximal to the Pinjin Fault (approximately 80km north of the Carosue Dam mill).
The aircore drilling which commenced in FY19 has successfully identified a large anomaly (Okavango) to the west of Safari Bore. This significant anomaly is now defined over a strike length of 6.0km and is up to 1.2km wide. The Okavango prospect is a strong basement anomaly that is coincident with albite-sericite alteration and key pathfinder elements including; As, Bi, Mo, Sb, Te and Ce.
The aircore drill spacing at Okavango will be closed in to 200m lines during the remainder of the December quarter to better understand the geology and define the core of the anomaly. This will then form the basis of the initial deep test for primary mineralisation.
The recent wide spaced air core drilling further south has identified a new anomaly that strikes north-northwest between the Two Lids Fault and the Pinjin Fault. This new anomaly has been defined over a strike length of 6km.
Figure 9 - Mt Celia, Air core drilling results
Further air core drilling is planned during FY20 to complete the full program to the south and infill significant zones of anomalism defined during FY19 and FY20.
