VANCOUVER, British Columbia, Dec. 16, 2021 (GLOBE NEWSWIRE) — Novo Resources Corp. (“Novo” or the “Company”) (TSX: NVO, NVO.WT & NVO.WT.A) (OTCQX: NSRPF) is pleased to advise that drilling has recently commenced (Figure 1) on a number of high-priority gold targets (Figure 2) at the Malmsbury Project (RL6587), approximately 50 km SSW of the high-grade Fosterville gold mine. Targeting has relied on significant exploration work conducted by the Novo/GBM team throughout 2021, including detailed 1:500 scale mapping, rock chip and grid soil sampling, 3D modelling and an airborne FALCON® gravity survey.
Novo acquired a 50% interest in the Malmsbury Project from ASX-listed GBM Resources Limited (ASX: GBZ) (“GBM”) in May 2021 and has the initial right to earn up to an additional 10% interest by incurring A$5 million in exploration expenditure over a four-year period2. GBM are currently managing the project.

Exploration Results and Summary from 2021
Mapping and Petrology – Detailed 1:500 scale mapping was conducted by Novo staff in the first half of 2021, aiding in defining the deep-seated regional Taradale Fault in the west of the Malmsbury Project, four main anticlinal structures trending the length of the project, zones of intense silicification, sulphidation and stockwork quartz veining, and the broad structural framework of the project area. Mapping (Figure 2) has highlighted significant anticlines and mineralized west dipping fault zones similar to the setting of the high-grade Fosterville deposit and extended the Leven Star mineralized trend to the SW of its previous known extent.
Coupled with mapping, historic workings (>1,000) and historic exploration costeans (>500) were field verified (GPS located) and accurately mapped with the aid of high-resolution LIDAR imagery acquired in 2020. Rock chip sampling also relied on mapping and historic workings location for selection criteria.
Importantly, mapping also defined a porphyritic monzogranite intrusion in the Belltopper Hill area with an outcrop expression over 340 m strike and up to 40 m width. The central portion of the granite, known as the Missing Link Granite, has incredible unidirectional solidification textures (“UST”) (Figure 3) typical in the carapace of IRG systems3 and these are overprinted by gold mineralized sheeted to stockwork quartz veins (Figure 3) and intense greisen style alteration defined by petrological studies. The intrusion will be targeted as an IRG system but also as a brittle host to orogenic vein style mineralization, similar to historic deposits including the Morning Star-Woods Point diorite-hosted ladder vein deposit owned by AuStar which produced over 800,000 oz of gold at 26.5 g/t Au tonne4.
One historic diamond drill hole (DDHMA3)5 intersected the Missing Link Granite, which was not recognized. Assaying of the hole by Novo/GBM, which was collared near the contact of the granite (top 18 m of hole missing as roller bit was used) yielded 23 m @ 0.46 g/t Au (at 0.1 g/t Au cut-off) from 18 m. Surface sampling yielded assay results up to 9.74 g/t Au from quartz veins within the granite.
Rock Chip Sampling – Results for 413 rock chip samples were received throughout the year, providing critical information on gold endowment and multielement associations and providing a useful targeting parameter. Over 17% of the samples assayed >1g/t Au with peak assay results of 27.1 g/t Au and 14.2 g/t Au on the Leven Star trend (Table 1).
Soil Sampling – Results for 474 grid soil samples taken in 2021 were recently received, with a further 150 results pending. Sampling was aimed at infilling older soils grids and expanding coverage across the RL. Approximately 11% of the samples assayed >100 ppb Au with a peak assay of 1.47 g/t Au and 89 ppm Sb. Soil sampling has provided an excellent vector for drill targeting with strong Au, As and Sb anomalies defining key targets (Figure 4). Soil sampling has also defined zoned multielement patterns around the Missing Link Granite with intrusion-related geochemical signatures, including a strong Mo core (Figure 4) zoning outward to Sn, Bi and W and potentially Sb and Au,
The aforementioned results are not necessarily representative of mineralization throughout the Malmsbury Project.
FALCON® Gravity – A FALCON® airborne gravity gradiometer and aeromagnetic survey was flown in May 2021, totalling 537.6 line kilometres. The gravity survey identified a large gravity low (1.5 x 0.8 km) potentially related to the monzogranite intrusion which crops out in the western edge of the gravity low feature. The Leven Star Lode lies on the edge of and is parallel to the gravity low (Figure 5).
Drilling Program 2021 – 2022
A minimum of 2,000 m of diamond drilling is planned during late 2021 and the first quarter of 2022 to test multiple high-ranking targets (Figure 2).
- Drilling will target a shoot on the Leven Star Lode where historic reverse circulation (“RC”) drilling intersected 7 m @ 4.84 g/t Au (LSCR014) including 3 m @ 9.38 g/t Au from 54 m1. Drilling will also test up and down dip positions adjacent to high-grade intersections on the main Leven Star Lode for deposit extension and metallurgical test work purposes.
- As a preliminary test, one 350 m drill hole will extend west along the Leven Star Lode to intersect the junction of a number of mineralized trends including Leven Star, Panama South and Missing Link (Figure 2). Surface mapping and soil and rock chip sampling have highlighted strong gold and multielement geochemistry and intense sheeted quartz veining and silica alteration are present at surface.
- The newly discovered Missing Link Granite, including Missing Link and Hanover West historic reefs (Figure 2) will be drill tested with one 400 m drill hole as an initial scout to identify the geometry and gold endowment of the monzogranite at depth. As stated above, the intrusion will be targeted as an IRG system but also as a brittle host to orogenic vein style mineralization.
- The Never Despair historic workings are centred on a convergence of four separate reefs. Rock chip sampling from waste rock spoils yielded consistent grades averaging 1.96 g/t Au and 260ppm Sb and peak results of 5.66 g/t Au. Drilling will aim to intersect the target down plunge at depth
- Drilling of two holes initially will test beneath the Queens-Egyptian and O’Connor’s Historic reefs to test down dip continuity of high-grade historic reefs.
The aforementioned results are not necessarily representative of mineralization throughout the Malmsbury Project.
Forward Work Program 2022
Subsequent to the 2,000 m drilling program, future work programs include a further second phase of drilling in late 2022, IP to define disseminated sulphide haloes around various gold targets including potential IRG mineralization, further expansion of systematic soil geochemistry, mapping and rock chip sampling.
Soil sampling is 20 to 60 cm depth B horizon sampling sieved to -80 mesh at the lab and analysed at ALS Brisbane for Au using four acid digest 30g charge fire assay with ICPAES finish (method Au-ICP21) and multielements using four acid digest Super Trace Lowest detection limit ICPMS (method ME-MS61L).
Rock chip samples and drill core is assayed at ALS Brisbane using the using four acid digest ore grade 30g charge fire assay with AA finish (method Au-AA25) and multielements using four acid digest ICPMS (method ME-MS61) after pulverization.
QAQC for soil samples is completed at the rate of 4 field duplicates, 2 standards and 2 blanks per 100 samples. QAQC for rock chip samples and drill core was completed at the rate of 3 standards and 3 blanks per hundred samples.
To date, there have been no limitations to the verification process and all relevant data has been verified by a qualified person as defined in NI 43-101 by reviewing analytical procedures undertaken by the various laboratories.
