Stacked Zones of Gold Mineralisation Discovered at Rohav Mountain in Cambodia
Highlights
- Stacked zones of shallow-dipping gold mineralisation, hosted in a highly altered, >150m wide diorite intrusion, discovered under soil and basalt cover at Rohav Mountain Prospect at the Ngot Gold Project in Cambodia. Best results from Rohav Mountain include:
- 23 m @ 0.9 g/t gold from 120 m, including 6 m @ 1.9 g/t gold (26DDRM007)
-
1 m @ 7.9g/t gold from 33 m (26DDRM008)
-
Additional high-grade gold intersections received at Ngot Central Prospect in shallow-dipping, stacked veins also hosted in diorite. The best new intersections at Ngot Central lie along the same vein and include:
- 0.4 m @ 32.8 g/t gold from 41.7 m (26DDNC009)
-
0.7 m @ 14.3 g/t gold from 22.4 m (26DDNC012)
-
This high-grade vein shows strong continuity and has now been traced for >200 m down-dip.
-
The stacked, shallow-dipping, gold mineralisation at Ngot is similar to the Intrusion-Related Gold (IRG) style of mineralisation seen at the Okvau Mine ~2km to the north of the Ngot licence.
-
To date, the 8,000 m (50-hole) diamond drilling program is nearly 90% complete, with drilling presently underway on the Ngot NE Prospect, the closest prospect to the Okvau Mine. Assays have been received for approximately 40% of the drilling and are currently pending for 19 completed holes (Rohav Mountain, Srolao and Ngot NE prospects).

The newly reported intersection of 23 m @ 0.9 g/t gold ends at 143 m. Gold is closely associated with a later generation of vuggy quartz veins with strong poly-metallic sulphides (pyrite – arsenopyrite – sphalerite and lesser galena) which is indicative of an epithermal-style mineral assemblage. The photograph depicts the transition between strongly altered and gold mineralised diorite and weakly altered and unmineralised diorite.

Craig Mackay, Unity's Founder and Managing Director, said:
"We are excited about the discovery of broad zones of stacked stockwork vein gold mineralisation in a 150 m wide, highly altered, diorite intrusion at Rohav Mountain which lies under shallow soil and basalt cover. Unlike our other prospect areas at Ngot we had only patchy surface geochemistry to guide our drill targeting at Rohav Mountain so to hit significant mineralisation in our first holes is highly encouraging. It is still early days at Rohav Mountain. We have not yet determined the extent of the gold mineralisation, nor where it may be strongest, and we eagerly await the assays for additional holes we have completed at the prospect."
"We are also pleased with our new assays from Ngot Central and the strong continuity we are starting to see in the gold mineralisation. We now have intersections including 0.7 m @ 14.3 g/t gold, 4.9 m @ 3.2 g/t gold and 0.4 m @ 32.4 g/t gold in the same shallow-dipping, high-grade vein that has currently been defined from surface to >200 m down-dip."
Unity Metals Limited ("Unity" or "the Company") is pleased to announce diamond drilling results for an additional 15 holes from its Ngot Gold Project (Ngot) in Cambodia.

Rohav Mountain Prospect
Gold mineralisation at the Rohav Mountain Prospect is associated with stockwork quartz – pyrite – arsenopyrite +/- sphalerite – galena veins that extend beneath a shallow basalt cap. The best outcropping veins are exposed in bedrock artisanal workings (including the Vietnamese Adit) in the side of a creek cutting through the basalt (Figure 3). A rock chip sample from this mineralisation returned 24.7 g/t gold, 206 g/t silver, 0.9% lead, and 4.4% zinc (Figure 5). The creek that exposes the primary mineralisation drains to the west to the most extensive artisanal alluvial gold workings in the entire Ngot Gold Project area.
To date, Unity has drilled 13 diamond holes (26DDRM001 – 013) for 2,713.3 m at Rohav Mountain. Hole details are provided in Table 1 and hole locations are depicted in Figure 3. The drill holes were designed to test the high-grade gold bearing veins exposed in bedrock artisanal workings, the gold-in-soil anomalies associated with this area of workings and a number of strong Induced Polarisation chargeability anomalies that lie beneath the basalt cap and alluvial cover.

Assays have been received for 5 holes (26DDRM001, 26DDRM005 - 008) and significant results are provided in Table 2. Stacked zones of shallow-dipping gold mineralisation, hosted in a diorite intrusion, were discovered under soil and basalt cover in holes 26DDRM006 - 008. The best gold intersections received in these holes include:
23 m @ 0.9 g/t gold from 120 m, including 6 m @ 1.9 g/t gold (26DDRM007); and
1 m @ 7.9g/t gold from 33 m (26DDRM008) (Figures 2 & 4).
The diorite intrusion is more than 150 m wide, vertically dipping and surrounded by hornfelsed sediments (Figure 2). The intrusion is currently interpreted to be 700 m long and its full extent is currently unknown (Figure 3). To the north, the diorite extends under shallow basalt cover.
Figure 4: Photograph of diamond drill hole 26DDRM008 from 32.60 m to 37.15 m (downhole) at Rohav Mountain, showing the highly altered diorite host rock, the multi-generational stock work quartz veins and the newly reported intersection of 1 m @ 7.9 g/t gold from 33 – 34 m. Intensely mineralised zones of stockwork veins and strong alteration occur throughout the diorite, however gold is closely associated with a later generation of vuggy quartz veins with strong poly-metallic sulphides (pyrite – arsenopyrite – sphalerite and lesser galena).
Within the diorite there are multiple generations of stockwork veins and breccia. There is an earlier generation of strong phyllic alteration (quartz – sericite – pyrite) and an intense quartz vein stockwork with weak – moderate sulphides and then a later overprinting generation of an intense quartz vein stockwork, some veins replacing bladed calcite, with strong poly-metallic sulphides (pyrite – arsenopyrite – sphalerite and lesser galena). The later veins being indicative of an epithermal-style mineral assemblage (Figures 1 & 4). The gold mineralisation seems to be predominantly related to these epithermal veins. Whilst mainly confined to the diorite, the mineralisation does extend into the surrounding hornfels for up to 25 m.
The gold mineralisation discovered in the altered diorite lies around 400 m directly upstream from the area of alluvial artisanal mining where the miners are currently recovering angular gold nuggets from alluvium to 2 m depth (Figure 3). Some gold nuggets are attached to angular quartz vein fragments. The angular nature of the nuggets and the quartz fragments suggests they haven't travelled far from the source.
Assays are pending for the remaining 8 holes completed at Rohav Mountain.

Ngot Central Prospect
At the Ngot Central Prospect a strong and coherent gold-in-soil anomaly (>10 ppb; maximum 5,390 ppb gold) is associated with a 1.5 km x 1 km diorite intrusion. There are multiple historical and active artisanal mine pits within the diorite which have exposed gold-bearing sheeted and stockwork quartz +/- arsenopyrite, pyrite, pyrrhotite veins. These veins have yielded rock chip assays up to 64.9 g/t gold.
To date, Unity has drilled 16 diamond holes (26DDNC001 – 016) for 2,530.3 m at Ngot Central. Hole details are provided in Table 1 and hole locations are depicted in Figures 6 & 7. The drill holes were designed to test the strongest portions of the gold-in-soil anomaly, high-grade gold bearing veins exposed in artisanal workings, and a number of strong Induced Polarisation chargeability anomalies that lie beneath.
Assay results for 6 holes were reported previously. Assays have been received for the remaining 10 holes (26DDNC005, 007 – 009, 011 – 016) and significant gold intersections are provided in Table 2.
Additional high-grade gold intersections have been received in the eastern portion of the prospect area in shallow-dipping, stacked quartz – pyrite – arsenopyrite veins hosted in diorite. The best new intersections at Ngot Central lie along the same vein and include:
- 0.4 m @ 32.8 g/t gold from 41.7 m (26DDNC009); and
- 0.7 m @ 14.3 g/t gold from 22.4 m (26DDNC012) (Figure 6).
This high-grade vein shows strong continuity and has now been traced for >200 m down dip.

Srolao Prospect
Gold mineralisation at the Srolao Prospect is associated with sheeted quartz – arsenopyrite veins hosted in sediments. In general, the gold-bearing veins at the Srolao Prospect are some of the thickest (up to 0.5 m wide) discovered within the Ngot Gold Project to date. Several small diorite intrusions lie immediately to the east of the prospect area.
Unity Metals has observed gold prospecting pits and trenches on the Srolao Prospect. The main area of these previous workings extends over 600 m, with a series of workings along parallel gold-bearing veins within an 80 m wide corridor. The Company believes this work was conducted by the previous licence holder over the Ngot Licence area, China Forwin Co., Ltd.. Unity Metals' rock chip samples from this mineralisation have been consistently high grade, with assays up to 27.4 g/t gold.
A series of stacked gold-in-soil anomalies (>10 ppb gold) have been outlined by Unity Metals. Each of these anomalies extend over 1 km in length. The peak assay from the soil sampling is 5,910 ppb gold (Figure 8).
To date, Unity has drilled 9 diamond holes (26DDSL001 – 009) for 1,238.3 m at Srolao. Hole details are provided in Table 1. The drill holes were designed to test the high-grade gold bearing veins exposed in bedrock artisanal workings and the gold-in-soil anomalies associated with this area of workings.
Narrow (<1 m wide) mineralised zones with laminated quartz – arsenopyrite veins have been observed in the drilling to date.
Assays for all holes at Srolao are pending.
Ngot NE Prospect
The Ngot NE Prospect is the closest prospect to the Okvau Mine (Figure 8). Outcrop is very sparse. Gold mineralisation is associated with quartz ± arsenopyrite veins and vein breccias that are hosted in diorite and the western diorite/sediment contact and observed in a few scattered and small artisanal pits. Rock chip samples from this mineralisation returned assays up to 2.2 g/t gold.
A coherent gold-in-soil anomaly (>10 ppb gold) with a peak assay of 1,000 ppb gold covers an area of 2 km x 0.7 km and extends up to the boundary of Unity Metals' Ngot Gold Project and Emerald's adjoining mining licence (Figure 9). A feature of the Ngot NE Prospect is that it is partly defined by the largest and strongest arsenic-in-soil anomaly within the Ngot Project area. The maximum arsenic-in-soil assay is 763.4 ppm. The arsenic in soil anomalies is closely associated with the gold-in-soil anomaly.
To date, Unity has drilled 2 diamond holes (26DDNE001 – 002) for 323.8 m at Ngot NE and currently a further 7 holes are planned. Hole details are provided in Table 1. The drill holes were designed to test gold-in-soil and arsenic-in-soil anomalies.
Arsenopyrite-rich veins, forming continuously mineralised intervals up to 3 m wide, have been observed in the drilling to date.
Assays for all holes at Ngot NE are pending.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques | Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.Aspects of the determination of mineralisation that are Material to the Public Report.In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. | Diamond core was sampled as per industry standard, using half-core where the core is cut in half down the longitudinal axis and sample intervals were determined by the geologist based on lithological contacts, with most of the sample intervals being 1 metre in length. Minimum sample interval was 30cm.Sample size is nominally 2 to 3 kilograms.Samples were submitted to the ALS laboratory in Phnom Penh, Cambodia for analysis. The sample preparation was conducted in Phnom Penh where the entire samples were fine crushed (CRU3-1) and pulverised to a nominal 85% passing -75μm (PUL-21). A 100g pulp split (SPL-22Y) was then sent to ALS laboratories in Vientiane, Laos for gold analysis via 50g charge fire assay with Atomic Absorption Spectrometry (AAS) finish (AU-AA26). Any fire assays over 30,000ppb gold are check assayed via gravimetric analysis (AU-GRA22). A second 100g pulp split will be returned for multi-element work with the company's pXRF unit. |
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). | For drill holes 26DDNC001 - 003, 005, 007, 009, 011, 014, 016, 26DDSL001 - 009, 26DDNE001 - 002 DDA track mounted HYDX-A diamond drilling rig was used to drill the holes reported in this release. Drilling commenced in the soil and weathered zone with PQ (85mm) diameter drill core. When fresh, competent rock was encountered the drilling was changed to HQ3 (63mm) diametre drill core.For drill holes 26DDNC004, 006, 008, 010, 012-013, 015, 26RH001 - 013 a man - portable diamond drilling rig was used to complete these drill holes. Drilling began in HQ (63) and when competent ground was reached the drilling changed to NTW3 (56.11 mm) diametre diamond core. NTW3 is a triple tube designation that indicates the use of an additional inner split tube. This reduces the final core diameter slightly but significantly improves core recovery and protection in fractured or soft |

| The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. | Exploration and mining is permitted within these protected areas subject to government approval. Exploration in the Unity licences was approved by the Ministry of Mines and Ministry of Environment following the completion of an Interim Environmental & Social Impact Assessment (IESIA). Government approval for mining is subject to the submission of an acceptable Definitive Feasibility Study and Final Environmental & Social Impact Assessment (FESIA). Emerald Resources NL's Okvau Gold Mine was approved in a protected area. A portion of the protected area was excised for the mining licence. | |
| Exploration done by other parties | Acknowledgment and appraisal of exploration by other parties. | Unity's Cambodian licences have seen very limited previous mineral exploration. |
| Geology | Deposit type, geological setting and style of mineralisation. | The Cambodian licences are prospective for intrusion-related gold ("IRG") and porphyry copper-gold mineralisation. Unity's Ngot and O'Phlay licences lie 2.5km south and 63km east-northeast respectively of the Okvau Gold Mine operated by Emerald Resources NL (ASX:EMR). |

If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. | Appropriate locality maps and tabulated collar data for the drill holes are provided in the body of the report or in Table 1. Details of significant drilling results are shown in Table 2. There has been no exclusion of information. |

| Relationship between mineralisation widths and intercept lengths | These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known'). | All reported intersections are down hole lengths. True widths are unknown and vary depending on the orientation of target structures. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. | Appropriate maps and sections are included in the body of this release. |
| Balanced reporting | Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. | All significant drilling results being intersections with a minimum 1 gram metre values are reported in Table 2. Soil and rock chip geochemical anomalies are depicted on the attached maps with sample points locations denoted and soil and rock chip symbols coloured by gold levels. |
| Other substantive exploration data | Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. | Surface geological mapping and Dipole-Dipole Induced Polarisation survey results have helped inform the geological models. |
