2019 Results   

Annual Report & Accounts

Griffin Mining Limited ("Griffin" or the "Company") has today published its annual report and financial statements for the year ended 31 December 2019 which are available on the Company's web site wwww.griffinmining.com. The release of these were delayed by travel restrictions within and to China imposed by authorities to contain the Coronavirus pandemic preventing Company personnel and the auditors completing their work at Caijiaying.

In 2019, the Company and its subsidiaries (together the "Group") recorded;

·    Revenues of $82,267,000 (2018: $99,067,000);

·    Operating profit of $14,225,000 (2018: $35,555,000);

·    Profit before tax of $11,712,000 (2018: $34,798,000);

·    Profit after tax of $6,084,000 (2018: $25,477,000); and

·    Earnings of 3.52 cents per share (2018: 14.83 cents).

Lower profits in 2019 were primarily caused by falling zinc prices and significantly higher smelter treatment charges resulting in lower zinc metal in concentrate prices received by the Group.

Despite greater quantities of zinc metal in concentrate being produced and sold, zinc metal in concentrate sales before royalties and resource taxes in 2019 amounted to $55,627,000 compared with $78,821,000 in 2018. Lead and precious metal in concentrate sales amounted to $29,850,000 compared with $24,920,000 in 2018.

In 2019, metal in concentrate sales were:

·    Zinc 37,811 tonnes (2018: 36,672 tonnes);

·    Gold 17,712 ounces (2018: 16,206 ounces);

·    Silver 333,093 ounces (2018: 279,632 ounces); and

·    Lead 1,221 tonnes (2018: 1,027 tonnes).

Average prices achieved in 2019 were:

·    Zinc metal per tonne of $1,471 (2018: $2,149);

·    Gold metal per ounce of $1,318 (2018: $1,173);

·    Silver metal per ounce of $13.8 (2018: $12.60); and

·    Lead metal per tonne of $1,575 (2018: $2,250).

Cost of sales of $48,609,000 in 2019 were up 6.1% on that incurred in 2018 of $45,798,000. This increase may be attributed higher mining costs with additional rock bolting and meshing costs and additional depreciation provisions reflecting increased costs capitalised being depreciated. Haulage costs were broadly in line with that incurred in 2018 and processing (milling) costs were marginally down on that incurred in 2018.

Administration expenses (including those of the Caijiaying Mine) rose $1,719,000 (9.7%) from $17,714,000 in 2018 to $19,433,000 in 2019. This increase arises mainly from inflationary increases;  the pursuit of the mining licence over Zone II; levies and  other costs in complying with Chinese health, safety and environmental requirements; and the expansion of activities of China Zinc in investigating potential ventures elsewhere in China.

Foreign exchange losses of $93,000 (2018: gains $42,000) were recorded in 2019.

Interest of $171,000 (2018: $223,000) was received on bank deposits in 2019 whilst $51,000 (2018: $Nil) was paid on short term bank loans.

Losses on the disposal of fixed assets of $305,000 (2018: $939,000) were recorded.

Provision of $1,985,000 (2018: $Nil) has been made to fully provide against the costs capitalised in respect of Hebei Sino Anglo's exploration licence area. Griffin intends to agree a contractual right to the licence to be transferred to Griffin's joint venture partner, prior to expiry of the licence in July 2020.

Finance costs on the lease of the dry tailings facility at Caijiaying Mine and the London and Perth offices totalling $326,000 (2018: $283,000) were incurred.

Income taxes of $5,628,000 (2018: $9,321,000) have been charged in 2019. This includes a deferred taxation charge of $380,000 (2018: credit $343,000).

Basic earnings per share in 2019 was 3.52 cents (2018: 14.83 cents) and diluted earnings per share was 3.24 cents (2018 13.35 cents).

Cash generated from operations of $21,639,000 (2018:  $20,439,000) have been used in further developing the Caijiaying Mine and facilities.

Attributable net assets per share at 31 December 2019 was $1.24 (2018: $1.22)

Chairman's Statement:

Although 2019 turned out to be a successful year operationally for the Company, very low commodity prices coupled with very high treatment charges produced a below average financial result.  In addition, as has been the case for far too many years to remember, any success was overshadowed by the continuing failure of regulatory authorities in China to issue the Company with its new mining licence over Zone II at the Caijiaying Mine.

Production of zinc, gold, silver and lead all increased in 2019 but prices received for zinc, gold and lead all decreased sharply leading to a 17% fall in revenue and a subsequent 60% fall in operating profit. For anyone who has ever read one of my Annual Report missives, my standard comment every year is that mining is a fixed cost business. Provided we can control our costs and maintain our production, we are at the vagaries of world commodity prices for our financial success, and even more importantly, to treatment charges offered by smelters in China.  Unfortunately, 2019 was a particularly bad year for both.

Operationally, the focus was on developing Zone III for greater, and more efficient, production and that was achieved by the continued development and linking of the North and South Declines and associated infrastructure down to the 1000mRL; the development of the South Haulage Drive in preparation for the commencement of development into Zone II; significant mine ventilation improvements including two new 5 metre diameter ventilation shafts developed from surface together with an underground 5 metre diameter ventilation shaft down to the 1175mRL level and the completion of three ventilation shafts (the Underground Fresh Air Shaft totalling 126 metres, the Main Exhaust Ventilation Shaft totalling 305 metres and the Central Fresh Air Shaft totalling 176 metres) significantly improving ventilation and the working environment underground.

Geologically, the resource base continued to expand. Even more astonishingly, the conversion rate at the Caijiaying Mine from an Inferred to a Measured or Indicated Resource is effectively 157% based on a comparison of previous and current Mineral Resource Estimate reports. This means that exploration and resource definition drilling is not only successfully converting existing Inferred mineralisation to higher categories, but also defining new Measured or Indicated mineralisation. This is an extraordinary statistic and gives enormous comfort for the ultra-long mine life the Company will enjoy at the Caijiaying Mine.

In addition, ongoing exploration has utilised knowledge gained from the evolving structural model at Zone III to enable re-interpretation of structure in the adjacent zones. This is allowing the resource models for Zones II and VIII to be more accurately measured, leading to the probability of new resource estimates to be released in 2020 for these zones.

Yet, in light of all the above progress, 2019 has been overshadowed by the extraordinary beginning to 2020, the effects which remain with us still and will do for at least the next decade and perhaps forever. At the Company level, the declaration of a pandemic by the government of the People's Republic of China on the 24 January 2020 due to the Coronavirus COVID-19 outbreak forced mining and underground development operations not to restart after the traditional 2 week mining shutdown for the Chinese New Year holidays. Ore stockpiled at surface was processed until exhausted on the 30 January 2020, at which time the mill was placed on care and maintenance. Operations restarted on the 21 February 2020. Underground mining operations reached 100% of planned rates by the 13 March 2020 and, with a new supply of ore, processing operations by late March 2020.  Nevertheless, international travel restrictions remain in place preventing foreign personnel returning to the Caijiaying due to the prohibition of entry into China to anyone other than Chinese citizens and permanent residents. This is currently having only a limited impact upon operations at the Caijiaying Mine.

At the operational level, we are grateful that we find our operations based in north-west China where COVID-19 virtually did not appear nor did it severely disrupt economic activity.  Further, we operate, and our commodities are sold, in China where the economy has virtually returned to full production, albeit not with the projected economic growth estimated in 2019.  It has been particularly pleasing to see the treatment charges start to fall significantly in the last 2 months, inevitably due to the lack of imports of foreign sourced concentrates by Chinese smelters.

At the Company level, thanks must be extended to the prudency of the directors with their long experience in the mining sector and the nature of the cyclical nature of commodities who only allowed debt to be incurred at the operational level to build or expand the operations at the Caijiaying Mine.  Retained earnings, which also could have been paid out in dividends, were retained for the same capital needs.  In addition, borrowings were never taken at the Griffin holding company level to buy back stock, something which will not only bankrupt a multitude companies, but also many industries, including the US Airline industry, without massive government assistance.

The COVID-19 crisis, debt laden balance sheets and the continuing low commodity price environment has shown the words of Warren Buffet to be truer than ever, "Only when the tide goes out do you discover who's been swimming naked."  The last 3 months has seen a large closure of marginal zinc mines and world zinc production falling by at least 10%.  This trend will inevitably get worse before it gets better, but it bodes well for the zinc price.

With the expectation of the granting of the new mining licence and the doubling of production, the Company appointed a new Nominated Advisor and Broker, Numis Securities Limited.  We look forward to a long and successful relationship as the Company takes the next giant step in its growth.

Penultimately, it's my privilege to thank the people who have gone, and continue to go, the extra yard to maintain the Company's status as the only foreign owned mining company operating in China.  That is an achievement almost none can imagine in its complexity, intricacy, difficulty and exhausting nature.  It deserves all of our thanks.  From the truly outstanding Company directors, our Chinese joint venture directors, our senior foreign staff, our Chinese operational staff, our contractors, consultants, Chinese government officials, spouses, partners and their children, I thank you for your time, excellence and dedication on behalf of the shareholders.  You have been extraordinary.

INCOME TAX EXPENSE (continued)

The parent company is not resident in the United Kingdom for taxation purposes.  Hebei Hua-Ao paid income tax in the PRC at a rate of 25% in 2019 (25% in 2018) based upon the profits calculated under Chinese generally accepted accounting principles (Chinese "GAAP").

EARNINGS PER SHARE

Reconciliation of the earnings and weighted average number of shares used in the calculations are set out below:

				2019						2018
	Earnings $000			Weighted Average number of shares		Per share amount (cents)		Earnings $000		Weighted Average number of shares		Per share amount (cents)
Basic earnings per share
Earnings attributable to ordinary shareholders	6,084			172,748,831		13.52		25,477		171,842,166		14.83
Dilutive effect of securities
Options	-			15,107,500		(0.28)		-		16,494,541		(1.30)
Diluted earnings per share	6,084			187,856,331		3.24		25,477		188,336,707		13.53

The calculation of the basic earnings per share is based on the earnings attributable to ordinary shareholders divided by the weighted average number of shares in issue during the year. The calculation of diluted earnings per share is based on the basic earnings per share on the assumed conversion of all dilutive options and other dilutive potential ordinary shares.

Mineral interests comprise the Group's interest in the Caijiaying ore bodies including costs on acquisition, plus subsequent expenditure on licences, concessions, exploration, appraisal and construction of the Caijiaying mine including expenditure for the initial establishment of access to mineral reserves, commissioning expenditure, and direct overhead expenses prior to commencement of commercial production and together with the end of life restoration costs.

Property, plant and equipment includes $1,997,000 (2018: $15,034,000) of assets under construction yet to be depreciated.

The offices, office furniture and equipment disclosed above relates solely to the fixed assets of the Company and China Zinc  Pty Limited.

Property, plant and equipment (continued)

During 2013 plant and equipment with a value of $11,381,000, revalued in 2019 to $14,150,000, were acquired under a finance lease, upon which depreciation of $5,123,000 (2018: $4,035,000) has been provided. At 31 December 2019 the net carrying amount of this equipment was $9,027,000 (2018: $7,534,000).  In 2019 the Company's London office lease was capitalised to comply with IFRS 16 with a value of $371,000 upon which depreciation of $114,000 has been provided in 2019. At 31 December 2019 the net carrying amount of this office was $247,000. 

The Group assesses the carrying value of the mineral interests, mill and mobile mine equipment at least annually, and more frequently in the event of any indications of impairment, most notably metal prices, by reference to discounted cash flow forecasts of future revenue and expenditure for each business segment.  These forecasts are based upon both past and expected future performance, available resources and expectations for future markets.

The directors have reassessed the net carrying value of capitalised costs at 31 December 2019, particularly in view of the decline in metal prices for zinc and smelter treatment charges experienced in 2019. In estimating the discounted future cash flows from the continuing operations at the Caijiaying mine the following principal assumptions were made:

·    Future market prices for zinc of $2,425 per tonne, gold of $1,500 per troy ounce and silver of $15 per troy ounce;

·    Zinc treatment charges of 30% of market prices;

·    Extraction of measured and indicated resources at Zone III at Caijiaying of 30 million tonnes with ore mined and processed at a rate of 1.2 million tonnes of ore per annum;

·    Operating costs, recoveries and payables based upon past performance and that budgeted for 2020;

·    Capital costs based upon that initially scheduled with sustaining capital based on future scheduling:

·    Discount interest rate of 10%; and

·    Continued maintenance and grant of applicable licences and permits. This assumes that Hebei Hua Ao will be converted to an equity joint stock company with an indefinite life without compensation to the Chinese Joint Venture Partner and that the business licence will be renewed at no significant cost.

Intangible Assets

China - mineral exploration interests

					$000

Intangible assets represent cost on acquisition, plus subsequent expenditure on licences, concessions, exploration, appraisal and development work in respect to regional exploration in China. Where expenditure on an area of interest is determined as unsuccessful such expenditure is written off to profit or loss. The recoverability of these assets depends, initially, on successful appraisal activities, details of which are given in the report on operations. The outcome of such appraisal activity is uncertain. Upon economically exploitable mineral deposits being established, sufficient finance will be required to bring such discoveries into production.  At 31 December 2019 impairment charges of  $1,985,000 (2018: $Nil) had been provided and charged to the income statement in respect of the above exploration costs previously capitalised by Hebei Sino Anglo. Griffin intends to agree a contractual right to transfer the exploration licence to Griffin's joint venture partner, Yuanrun, prior to expiry of the licence.

POST BALANCE SHEET EVENTS

Since the year end operations at Caijiaying were suspended for a month from 24 January to comply with restrictions instigated by the PRC authorities to contain the COVID 19 pandemic. Operations at Caijiaying recommenced on 21 February 2020 and have since steadily increased such that underground mining operations reached 100% of planned rates by mid-March and processing operations by late March. Since the re-commencement of operations at Caijiaying, restrictions in place to contain the coronavirus pandemic throughout China have relaxed, and as a result Hebei Hua Ao has been able to sell its output. As a result of these events, production and sale of metals in concentrate, and profitability was impacted in the first quarter of 2020, but has returned to planned levels subsequently.

As at 31 December 2019 there were no adjusting post balance sheet events (2018: none).
