Performance: Positive NAV TR in H120
Following a successful FY19, when BSRT reported c 30% NAV total return (TR) and outperformed the EMIX Global Mining Index (23% return), the fund looked to carry momentum forward into FY20, on the back of several potential NAV triggers. These included the conclusion of pre-feasibility (PFS) and definitive feasibility studies (DFS), granting mining licences by local authorities or launching production in certain venues, among others. However, early 2020 turned out to be a challenging period for the broad equity market due to the coronavirus outbreak, with BSRT’s performance also affected. We note, however, that the subsequent market rebound, coupled with BSRT’s positive organic developments, outweighed the initial impact of the pandemic.
Under ordinary circumstances, BSRT reviews the valuation of its unlisted investments twice a year, with a full review at the year-end and for interim financial statements. Having said that, this year the company decided to conduct a simplified portfolio revaluation as at end-March 2020, as well as providing the market with updated information on the COVID-19 impact. The procedure was not as comprehensive as the regular review, but based on the same methodology. Considering general market movements in mining equities, as well as company-specific factors and their potential impact on the carrying values of BSRT's unlisted holdings, the review resulted in a c 8.4% decline in NAV vs end February 2020 to 67.3p per share.
Subsequently, however, the regular interim review carried out at end-June 2020 resulted in a 10.3% NAV improvement vs end-May 2020, bringing the NAV per share to 77.2p. Consequently, BSRT’s performance in H120 was 4.5% NAV TR vs 5.8% posted by the EMIX Global Mining Index (not an official benchmark, but we use it as a broad reference for comparison). However, we note that the index (consisting of listed mining stocks) has enjoyed a stronger post-pandemic rebound since April, which has resulted in a c 40% increase over Q220 against just 14.4% recorded by BSRT.
BSRT has already announced its estimated NAV at end-July 2020, amounting to 75.5p per share, which constitutes a c 2.2% m-o-m decline. Given that BSRT conducts a more comprehensive portfolio valuation only twice a year, the monthly change in July was primarily driven by a 6% appreciation of sterling against the US dollar, in which around half of the company’s portfolio (including Bilboes and Polar Acquisition) is denominated. Simultaneously, the EMIX Global Mining Index went up by 6.6% in sterling terms in July. Consequently, one-year and three-year (annualised) NAV total returns at 31 July 2020 sit at 10.5% and 12.5%, respectively, vs 13.0% posted by the index in both periods. Expanding the analysed investment horizon further to five and 10 years reveals BSRT’s relatively weak performance in the early years since inception (28 April 2010), resulting in 13.3% and -2.4% annualised NAV total return, respectively, vs 19.6% and 1.2% demonstrated by the index.

The extent of downward revaluation at the end of March 2020, associated in particular with companies operating in the industrial metals and minerals sector, was partially mitigated by the relatively strong performance of gold mining companies, Bilboes and Polymetal. The latter initially recorded a c 19% share price fall between end January 2020 and mid-March 2020, but the subsequent rebound to end-March not only fully offset the earlier decline, but the continued rally also brought the share price to a record-high level in May 2020. This encouraged BSRT to sell almost all of its remaining holdings in Polymetal, bringing exposure to precious metals (including silver) to c 30% of the portfolio at end-May 2020, from c 35% at end-December 2019. The same applies to all listed shares in Ivanhoe Mines, which were also sold during May 2020. BSRT’s exposure to the precious metals sector increased to almost 40% at the end of July, on the back of improved valuations of unlisted holdings in this sector and the deployment of resources into highly liquid, listed precious metal shares, to provide working capital until these funds are reinvested in line with BSRT’s core strategy. As per our estimates, at end-H120 BSRT already held such equities valued at c £4.8m, which constituted c 5.8% of the portfolio. Following a strong rise of listed stocks over July 2020, their total value improved by over 28% to c £6.1m, reaching 7.6% share of the portfolio as at 31 July 2020.
Based on our calculations (including an adjustment for FX rate movements), we have identified five unlisted holdings, whose value has been cut by over 20% during the March review. The carrying value of Polar Acquisition (PAL), which holds a 0.9–1.8% royalty interest in the Prognoz Silver Project in Russia, has been reduced by c 22% in US$ terms. This was presumably attributable to the decline in the price of silver, which fell from US$16.39 per ounce at end February 2020 to just US$14.10 per ounce at end-March 2020, constituting a c 14% decrease. This has likely fed through to projected cash flows used in the royalties valuation model. We note that in FY19, PAL was subject to a c 50% upward revaluation in local currency on the back of revised estimates and production levels for the Prognoz project and an increase in silver prices. We also note, that on the back of the recent rebound in the silver price, which reached US$18.20/oz per ounce at 30 June 2020, an upward revaluation of this investment by c 25% (based on our estimations excluding FX impact) has been done during the interim review in June 2020.
Due to the unfavourable outlook for the global industrial sector, which affects the pricing of comparable listed companies, the valuations of BSRT’s investments from the segment: Cemos (cement producer and oil shale explorer), Anglo Saxony Mining (tin producer), Sarmin (potash) and PRISM (iron ore) have been reduced by 25% to 35% at end-March 2020. However, we note that in the same review, Futura Resources – a coking coal mining company – recorded only a 6.3% decrease in value (taking into account FX moves), with the approaching launch of first production at its mines possibly being a mitigating factor, as it would bring Futura further up the development curve to the production stage (see Exhibit 4). Futura expected to obtain licences for both of its mines, Wilton and Fairhill, in Q220 and start mining operations in H220. The terms remain unchanged for the former, while the licensing process has been postponed to Q320 for the latter.
Importantly, in the interim review, out of five companies listed above, only Cemos and Anglo Saxony Mining saw improved valuations (by c 16% and 35%, respectively). As per our estimates, however, neither of these has seen its valuations reaching pre-pandemic levels yet. In the latter case, the updated valuation reflects the PFS results, which was completed in April 2020.
Mines & Metals Peru’s valuation was revised downwards by 13.5% during the interim review, due to disruptions associated with the COVID-19 lockdown (Peru has been particularly severely hit by the pandemic). This has fully offset the improvement in carrying value reported in March 2020, resulting in a 9% net fair value decline in H120, as per our estimates. At the same time, the company expects to increase its production and start processing ore from its own concessions in Q420, rather than treating ore from third parties, which constitutes the main potential NAV trigger for the year. Once the reverse takeover of Zincore is complete, the company plans to relist on the TSX Venture Exchange (Toronto). This was initially planned for this year, but due to the current market turmoil, the process has been postponed until 2021, when market conditions might be more convenient.

On the other hand, in the H120 portfolio review, BSRT has finally reflected the positive impact of the DFS on Bilboes’ Isabella-McCays-Bubi gold project in Zimbabwe, completed shortly after the FY19 year-end. We estimate that, as part of the interim review, Bilboes’ valuation in local currency improved by c 31.5%, supported by the appreciation of listed African gold mining peers.
Initially, the Bilboes project was expected to start production at c 100k ounces of gold per annum, and then expand on the back of generated cash flow. However, following completion of the DFS, BSRT now assumes it will operate at full capacity of c 170k annually, which is considered an optimal investment strategy. At a cash all-in sustaining cost of $791 per ounce, the company estimates the total funding requirement for the project at US$253m. At a gold price of $1,500/oz (currently more than $2,000/oz) and 10% discount rate, the project’s NPV is estimated at just over US$236m, generating a c 33% post-tax IRR with the payback period slightly exceeding one year since the start of production. Based on the ‘consensus pricing scenario’ (recently disclosed by the company) which used Bloomberg forward gold pricing (US$1,782/oz) and then available consensus data for 2023 and 2024, the investment economics of the project improve to a NPV of US$294m and IRR of 38%.
BSRT reported a stable fair value of its stake in Nussir, which completed a DFS in March 2020, after a six-month delay resulting from the decision to conduct additional drillings. Consequently, Nussir upgraded additional resources to the measured and indicated categories, significantly enhancing the project’s economics. As a result, the potential project’s NPV sits at US$189.8m, against the initial estimate of $132.6m at 23% IRR, calculated without the upside resulting from additional resources.
Finally, in the June NAV update, BSRT confirmed completion of the technical and economic update of Hemerdon Tungsten Mine (held by Tungsten West), which has not yet resulted in an upward revaluation of the holding, pending a potential fundraising. This could also be partially attributable to the preliminary character of the review, with the DFS planned for Q121. Based on the underlying assumptions of capital cost to restart the mine, amounting to £35m and a discount rate of 5%, the financial model used by BSRT indicates £306m of post-tax NPV and IRR of 111%.

The remaining NAV triggers, expected to materialise within the next 12 months, include the PFS on the Prognoz Silver Project (royalty held by Polar Acquisition) and a DFS on Sarmin, which should be completed in H220, according to the investment manager. With the completion of construction works in the first plant in Tarfaya in December 2018 and capacity of c 270k tonnes of cement pa, Cemos is already reporting positive cash flow from its operations (and targets a cash flow of €8–10m pa at full capacity utilisation). In June 2020, it reported record sales of c 23k tonnes of cement, representing 92% of installed capacities and supporting the decision to start exploring options to launch a second production line, which would double potential annual output. Futura, as mentioned above, is planning to commence production after receiving mining licences, both expected in H220.
