A new home for a proven approach?
City Natural Resources Growth and Income (CYN) transferred its management contract to Tufton Investment Management in September 2026. The move retains longstanding portfolio managers Keith Watson and Robert Crayfourd, while providing access to Tufton’s energy and shipping expertise.
CYN has delivered positive returns, with its NAV rising 28.8% and its share price 37.2%, both on a total return basis, over the year to 31 October 2026. The managers appear to have benefitted from their exposure to precious metals miners before rotating towards energy as they considered relative valuations to have become more attractive.
Alongside its performance, the measures introduced in 2025 appear to have attracted shareholders to the share register and helped narrow CYN’s discount. The shares have recently traded close to NAV and occasionally at a premium, which enabled CYN to issue stock. CYN continues to offer a combination of specialist natural resources exposure, capital growth potential and income.
Capital growth and income from mining & resources
CYN aims to provide investors with capital growth and income by investing in a portfolio that predominantly comprises mining and resource equities, as well as mining, resource and industrial fixed-interest securities.

Preserving the managers’ expertise
Watson and Crayfourd resumed responsibility for the portfolio in September
City Natural Resources Growth and Income (CYN) transferred its investment management mandate from Manulife | CQS to Tufton Investment Management on 14 September 2026, following the departure of its longstanding portfolio managers, Keith Watson and Robert Crayfourd, from CQS. The board believes its decision to follow the managers to Tufton preserves the expertise, investment approach and stock-picking philosophy that have underpinned the trust’s long-term performance. Watson and Crayfourd, who have managed CYN since 2013, resumed responsibility for the portfolio in September. The trust was subsequently renamed City Natural Resources Growth and Income, although its ticker (CYN) remains unchanged.
Tufton states that it provides a complementary source of specialist research
Tufton believes its expertise in energy and shipping provides a complementary source of specialist research, industry contacts and market intelligence that could enhance the managers’ ability to identify opportunities across the natural resources universe. This is relevant given CYN’s exposure to oil and gas and its growing interest in shipping companies, where Tufton believes its sector knowledge could provide a competitive advantage.
Manager’s view
Outlook for natural resources dominated by geopolitical tensions
CYN’s managers believe that the outlook for natural resources continues to be dominated by geopolitical tensions, particularly the conflict in the Middle East and its impact on global energy supplies. Although some oil shipments through the Strait of Hormuz have resumed, attacks on shipping and energy infrastructure continue to disrupt supply chains.
There is a shortage of refined products, notably diesel, where refining margins have risen. The managers believe that these disruptions could prove more persistent than markets anticipate, citing this view in support of their exposure to oil and gas producers. They are also positive on shipping companies, including Frontline and BW LPG, which they believe are benefitting from longer shipping routes, reduced vessel availability and higher freight rates.
Precious metals remain a key area of conviction for the managers. Although higher energy prices appear to have increased inflationary pressures and pushed up interest rate expectations, potentially creating near-term headwinds for gold, the managers believe that the longer-term investment case remains compelling. High government indebtedness, currency debasement concerns and geopolitical uncertainty may support demand for gold, while producers appear to benefit from historically elevated margins. The managers favour gold mining equities, which they consider attractively-valued despite their strong performance and inherent volatility. They also believe these companies are better placed to absorb rising energy costs than many industrial miners.
By contrast, the managers remain cautious on copper and other base metals, where they believe demand is more exposed to a slowing global economy, particularly China. Although the expansion of AI data centres may provide an additional source of copper demand, they regard its contribution as relatively small compared with traditional uses such as construction and manufacturing. The portfolio remains positioned principally towards precious metals, energy and shipping, with relatively limited exposure to more economically sensitive commodities.
Asset allocation
Diversified portfolio that is biased to mid-caps and producers
As illustrated in Figures 1 and 2, CYN provides investors with natural resources exposure. The portfolio has a bias towards mid-cap stocks, but with limited exposure to exploration. CYN’s managers prefer companies that are cash-flow-generative and that they believe can sustain themselves through the cycle.
CYN’s portfolio has a bias towards mid-cap stocks and away from explorers.
The names of CYN’s top 10 holdings (see Figure 3) may be familiar to regular followers of the trust, which would seem to reflect the managers’ long-term approach to portfolio turnover (typically around 50% per annum, but much of this may involve trimming stocks which are approaching their target price, and adding to holdings where the managers see a better risk-reward).
Figure 1: Sectoral allocation as at 30 September 20261

Figure 2: Geographic allocation as at 30 September 20261,2

Over the past six months, sectoral allocation changes were +2.5% for shipping; -2.0% for oil and gas; and -2.4% for uranium. The main geographical allocation changes – reflecting the location of a company’s principal operations – were +4.0% to global; +0.8% to Asia; +1.8% to Australia; -4.9% to Africa; -1.1% to UK/Europe; and -0.7% to Latin America.
Top 10 holdings

| Total of top 103 | 36.4 | 36.6 | (0.2) | ||
| Total of top 203 | 59.0 | 58.0 | 1.0 |
Tamboran Resources (4.7%) has reached a milestone in developing Australia’s Beetaloo Basin, delivering its first gas into the Northern Territory market in September 2026. The Shenandoah South pilot project is now being commissioned, while further drilling and testing may help establish the commercial potential of the resource. The company also completed its acquisition of Falcon Oil & Gas in May, expanding its position in the basin.
NexGen Energy (4.6%) made progress towards developing its high-grade Rook I uranium project in Saskatchewan, Canada, when the Canadian Nuclear Safety Commission granted a site preparation and construction licence in March 2026. This may reduce regulatory uncertainty and allow the project to progress towards construction. Rook I may provide exposure to the longer-term demand outlook for nuclear fuel, although development and financing risks remain.
BW LPG (4.0%) has likely benefitted from freight market conditions as disruption to Middle Eastern shipping routes may have tightened vessel availability. Second-quarter 2026 shipping earnings averaged $74,000 per available day, with approximately 92% of third-quarter capacity fixed at an average rate of $88,000 per day. The company declared a $0.95 quarterly dividend.
Emerald Resources (4.0%) continues to generate cash flow from its Okvau gold mine in Cambodia, producing 20,280 ounces during the September quarter. The company has maintained FY2027 production guidance of 100,000–115,000 ounces and is progressing developments at Dingo Range in Australia and Memot in Cambodia. These projects may support its ambition to become a multi-mine producer of more than 300,000 ounces annually.
Spartan Delta Corp (3.9%), the Canadian oil and gas producer, continues to expand its production base, particularly through its Duvernay assets in Alberta. Second-quarter 2026 production increased 37% year-on-year to 52,818 barrels of oil equivalent per day, alongside an increase in full-year guidance. The company considers its growing liquids exposure particularly attractive in the current energy market, although natural gas prices may influence earnings.
PDI Gold (3.7%), formerly Predictive Discovery, completed its April 2026 merger with Robex Resources. The combination brings together the producing Kiniéro and Nampala gold mines with PDI’s Bankan development project in Guinea. The enlarged group reported total gold ore reserves of 4.8 million ounces in September. Securing the necessary approvals to develop Bankan remains outstanding.
Talon Metals Corp (3.2%) is advancing its Tamarack nickel-copper-cobalt project in Minnesota, which could become a domestic source of critical minerals for the US. Recent drilling has identified high-grade intersections, while the company has selected the Humboldt Mill in Michigan as its proposed processing location. Environmental assessment work is progressing, but the project remains pre-production and exposed to permitting and financing risks.
Ora Banda Mining (2.9%) is pursuing an expansion of its Davyhurst gold operations in Western Australia. The company produced 33,305 ounces during the September quarter, although weather disruption and mill downtime may have contributed to higher costs. Development of the Waihi underground mine has commenced, while construction of a new three-million-tonne-per-annum processing plant is progressing. The company considers both central to its longer-term production growth plans.
West African Resources (2.8%) continues to increase production from its Sanbrado and Kiaka gold operations in Burkina Faso. September-quarter output reached a record 127,950 ounces, taking production for the first nine months of 2026 to 360,857 ounces. The company appears on course to achieve its full-year guidance of 430,000–490,000 ounces, although explosives availability at Kiaka appears to remain an operational constraint.
Frontline (2.6%), the crude oil tanker operator, appears to have benefited from the disruption to global shipping routes associated with the Middle Eastern conflict. It reported record second-quarter 2026 net profit of $659.2m, with its largest tankers earning average spot rates of $152,700 per day. The company declared a $2.61 quarterly dividend, reflecting its cash generation, although tanker earnings remain cyclical.
Performance
As discussed in previous notes, CYN’s managers tactically adjust the allocations to different resource areas depending on their expectations of how these may perform, while expressing them through allocating to their preferred ideas on a bottom-up basis. CYN’s managers consider this process to have been successful over the long term, with CYN’s NAV and share price outperforming the commodities indices, and global equities more generally, for most of the longer-term periods of three years and above.
Figure 4: CYN NAV/MSCI World Metals and Mining and CYN NAV/MSCI World Energy Sector – rebased to 100 over 10 years to 31 October 2026

Looking at more recent performance, CYN’s managers describe its performance between March 2025 and March 2026 as particularly strong, attributing this principally to its substantial exposure to precious metals miners, which they believe benefitted from an environment characterised by geopolitical uncertainty, concerns over government indebtedness, persistent inflationary pressures and growing demand for gold as a safe-haven asset. CYN’s managers favoured gold mining equities over the physical metal, which may have allowed the trust to capture the operational leverage that rising gold prices could provide to producers’ earnings and cash flows.

This contrasted with an apparently more challenging backdrop for industrial commodities and conventional energy, where the managers maintained a lower exposure. CYN appears to have benefitted as weakness in China’s property market and concerns over global economic growth may have weighed on demand expectations for base metals, while increasing OPEC production may have dampened the outlook for oil. Whilst the managers initially recycled capital within the gold mining portfolio – seemingly taking profits in companies that have rerated and reinvesting in smaller, less well-researched businesses where they see greater upside – from December 2025 through to March 2026, they reduced the trust’s exposure to gold and silver miners, reflecting these sectors’ performance, and increased exposure to energy where they saw more attractive valuations. This timing may have benefitted the trust, given the change in the energy price following the outbreak of war in Iran and the subsequent fall in the gold price as the market appeared to factor in higher interest rates.

CYN seeks to deliver both capital growth and income from a portfolio focused predominantly on mining and resource equities, complemented by selected mining, resource and industrial fixed income securities. The managers target companies that they believe are undervalued by the market and capable of generating attractive income relative to risk, potentially providing scope for capital appreciation over time. The portfolio has a mid-cap bias, which the managers believe offers more idiosyncratic exposure than large-cap-focused peers and a differentiated profile versus major resource indices and sector ETFs.
